  separator was missing.
* Added a better error message for when `body` is provided as an array. Please
  use `form_params` or `multipart` instead.
* Various doc fixes.

## 6.0.0 - 2015-05-26

* See the UPGRADING.md document for more information.
* Added `multipart` and `form_params` request options.
* Added `synchronous` request option.
* Added the `on_headers` request option.
* Fixed `expect` handling.
* No longer adding default middlewares in the client ctor. These need to be
  present on the provided handler in order to work.
* Requests are no longer initiated when sending async requests with the
  CurlMultiHandler. This prevents unexpected recursion from requests completing
  while ticking the cURL loop.
* Removed the semantics of setting `default` to `true`. This is no longer
  required now that the cURL loop is not ticked for async requests.
* Added request and response logging middleware.
* No longer allowing self signed certificates when using the StreamHandler.
* Ensuring that `sink` is valid if saving to a file.
* Request exceptions now include a "handler context" which provides handler
  specific contextual information.
* Added `GuzzleHttp\RequestOptions` to allow request options to be applied
  using constants.
* `$maxHandles` has been removed from CurlMultiHandler.
* `MultipartPostBody` is now part of the `guzzlehttp/psr7` package.

## 5.3.0 - 2015-05-19

* Mock now supports `save_to`
* Marked `AbstractRequestEvent::getTransaction()` as public.
* Fixed a bug in which multiple headers using different casing would overwrite
  previous headers in the associative array.
* Added `Utils::getDefaultHandler()`
* Marked `GuzzleHttp\Client::getDefaultUserAgent` as deprecated.
* URL scheme is now always lowercased.

## 6.0.0-beta.1

* Requires PHP >= 5.5
* Updated to use PSR-7
  * Requires immutable messages, which basically means an event based system
    owned by a request instance is no longer possible.
  * Utilizing the [Guzzle PSR-7 package](https://github.com/guzzle/psr7).
  * Removed the dependency on `guzzlehttp/streams`. These stream abstractions
    are available in the `guzzlehttp/psr7` package under the `GuzzleHttp\Psr7`
    namespace.
* Added middleware and handler system
  * Replaced the Guzzle event and subscriber system with a middleware system.
  * No longer depends on RingPHP, but rather places the HTTP handlers directly
    in Guzzle, operating on PSR-7 messages.
  * Retry logic is now encapsulated in `GuzzleHttp\Middleware::retry`, which
    means the `guzzlehttp/retry-subscriber` is now obsolete.
  * Mocking responses is now handled using `GuzzleHttp\Handler\MockHandler`.
* Asynchronous responses
  * No longer supports the `future` request option to send an async request.
    Instead, use one of the `*Async` methods of a client (e.g., `requestAsync`,
    `getAsync`, etc.).
  * Utilizing `GuzzleHttp\Promise` instead of React's promise library to avoid
    recursion required by chaining and forwarding react promises. See
    https://github.com/guzzle/promises
  * Added `requestAsync` and `sendAsync` to send request asynchronously.
  * Added magic methods for `getAsync()`, `postAsync()`, etc. to send requests
    asynchronously.
* Request options
  * POST and form updates
    * Added the `form_fields` and `form_files` request options.
    * Removed the `GuzzleHttp\Post` namespace.
    * The `body` request option no longer accepts an array for POST requests.
  * The `exceptions` request option has been deprecated in favor of the
    `http_errors` request options.
  * The `save_to` request option has been deprecated in favor of `sink` request
    option.
* Clients no longer accept an array of URI template string and variables for
  URI variables. You will need to expand URI templates before passing them
  into a client constructor or request method.
* Client methods `get()`, `post()`, `put()`, `patch()`, `options()`, etc. are
  now magic methods that will send synchronous requests.
* Replaced `Utils.php` with plain functions in `functions.php`.
* Removed `GuzzleHttp\Collection`.
* Removed `GuzzleHttp\BatchResults`. Batched pool results are now returned as
  an array.
* Removed `GuzzleHttp\Query`. Query string handling is now handled using an
  associative array passed into the `query` request option. The query string
  is serialized using PHP's `http_build_query`. If you need more control, you
  can pass the query string in as a string.
* `GuzzleHttp\QueryParser` has been replaced with the
  `GuzzleHttp\Psr7\parse_query`.

## 5.2.0 - 2015-01-27

* Added `AppliesHeadersInterface` to make applying headers to a request based
  on the body more generic and not specific to `PostBodyInterface`.
* Reduced the number of stack frames needed to send requests.
* Nested futures are now resolved in the client rather than the RequestFsm
* Finishing state transitions is now handled in the RequestFsm rather than the
  RingBridge.
* Added a guard in the Pool class to not use recursion for request retries.

## 5.1.0 - 2014-12-19

* Pool class no longer uses recursion when a request is intercepted.
* The size of a Pool can now be dynamically adjusted using a callback.
  See https://github.com/guzzle/guzzle/pull/943.
* Setting a request option to `null` when creating a request with a client will
  ensure that the option is not set. This allows you to overwrite default
  request options on a per-request basis.
  See https://github.com/guzzle/guzzle/pull/937.
* Added the ability to limit which protocols are allowed for redirects by
  specifying a `protocols` array in the `allow_redirects` request option.
* Nested futures due to retries are now resolved when waiting for synchronous
  responses. See https://github.com/guzzle/guzzle/pull/947.
* `"0"` is now an allowed URI path. See
  https://github.com/guzzle/guzzle/pull/935.
* `Query` no longer typehints on the `$query` argument in the constructor,
  allowing for strings and arrays.
* Exceptions thrown in the `end` event are now correctly wrapped with Guzzle
  specific exceptions if necessary.

## 5.0.3 - 2014-11-03

This change updates query strings so that they are treated as un-encoded values
by default where the value represents an un-encoded value to send over the
wire. A Query object then encodes the value before sending over the wire. This
means that even value query string values (e.g., ":") are url encoded. This
makes the Query class match PHP's http_build_query function. However, if you
want to send requests over the wire using valid query string characters that do
not need to be encoded, then you can provide a string to Url::setQuery() and
pass true as the second argument to specify that the query string is a raw
string that should not be parsed or encoded (unless a call to getQuery() is
subsequently made, forcing the query-string to be converted into a Query
object).

## 5.0.2 - 2014-10-30

* Added a trailing `\r\n` to multipart/form-data payloads. See
  https://github.com/guzzle/guzzle/pull/871
* Added a `GuzzleHttp\Pool::send()` convenience method to match the docs.
* Status codes are now returned as integers. See
  https://github.com/guzzle/guzzle/issues/881
* No longer overwriting an existing `application/x-www-form-urlencoded` header
  when sending POST requests, allowing for customized headers. See
  https://github.com/guzzle/guzzle/issues/877
* Improved path URL serialization.

  * No longer double percent-encoding characters in the path or query string if
    they are already encoded.
  * Now properly encoding the supplied path to a URL object, instead of only
    encoding ' ' and '?'.
  * Note: This has been changed in 5.0.3 to now encode query string values by
    default unless the `rawString` argument is provided when setting the query
    string on a URL: Now allowing many more characters to be present in the
    query string without being percent encoded. See http://tools.ietf.org/html/rfc3986#appendix-A

## 5.0.1 - 2014-10-16

Bugfix release.

* Fixed an issue where connection errors still returned response object in
  error and end events event though the response is unusable. This has been
  corrected so that a response is not returned in the `getResponse` method of
  these events if the response did not complete. https://github.com/guzzle/guzzle/issues/867
* Fixed an issue where transfer statistics were not being populated in the
  RingBridge. https://github.com/guzzle/guzzle/issues/866

## 5.0.0 - 2014-10-12

Adding support for non-blocking responses and some minor API cleanup.

### New Features

* Added support for non-blocking responses based on `guzzlehttp/guzzle-ring`.
* Added a public API for creating a default HTTP adapter.
* Updated the redirect plugin to be non-blocking so that redirects are sent
  concurrently. Other plugins like this can now be updated to be non-blocking.
* Added a "progress" event so that you can get upload and download progress
  events.
* Added `GuzzleHttp\Pool` which implements FutureInterface and transfers
  requests concurrently using a capped pool size as efficiently as possible.
* Added `hasListeners()` to EmitterInterface.
* Removed `GuzzleHttp\ClientInterface::sendAll` and marked
  `GuzzleHttp\Client::sendAll` as deprecated (it's still there, just not the
  recommended way).

### Breaking changes

The breaking changes in this release are relatively minor. The biggest thing to
look out for is that request and response objects no longer implement fluent
interfaces.

* Removed the fluent interfaces (i.e., `return $this`) from requests,
  responses, `GuzzleHttp\Collection`, `GuzzleHttp\Url`,
  `GuzzleHttp\Query`, `GuzzleHttp\Post\PostBody`, and
  `GuzzleHttp\Cookie\SetCookie`. This blog post provides a good outline of
  why I did this: http://ocramius.github.io/blog/fluent-interfaces-are-evil/.
  This also makes the Guzzle message interfaces compatible with the current
  PSR-7 message proposal.
* Removed "functions.php", so that Guzzle is truly PSR-4 compliant. Except
  for the HTTP request functions from function.php, these functions are now
  implemented in `GuzzleHttp\Utils` using camelCase. `GuzzleHttp\json_decode`
  moved to `GuzzleHttp\Utils::jsonDecode`. `GuzzleHttp\get_path` moved to
  `GuzzleHttp\Utils::getPath`. `GuzzleHttp\set_path` moved to
  `GuzzleHttp\Utils::setPath`. `GuzzleHttp\batch` should now be
  `GuzzleHttp\Pool::batch`, which returns an `objectStorage`. Using functions.php
  caused problems for many users: they aren't PSR-4 compliant, require an
  explicit include, and needed an if-guard to ensure that the functions are not
  declared multiple times.
* Rewrote adapter layer.
    * Removing all classes from `GuzzleHttp\Adapter`, these are now
      implemented as callables that are stored in `GuzzleHttp\Ring\Client`.
    * Removed the concept of "parallel adapters". Sending requests serially or
      concurrently is now handled using a single adapter.
    * Moved `GuzzleHttp\Adapter\Transaction` to `GuzzleHttp\Transaction`. The
      Transaction object now exposes the request, response, and client as public
      properties. The getters and setters have been removed.
* Removed the "headers" event. This event was only useful for changing the
  body a response once the headers of the response were known. You can implement
  a similar behavior in a number of ways. One example might be to use a
  FnStream that has access to the transaction being sent. For example, when the
  first byte is written, you could check if the response headers match your
  expectations, and if so, change the actual stream body that is being
  written to.
* Removed the `asArray` parameter from
  `GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
  value as an array, then use the newly added `getHeaderAsArray()` method of
  `MessageInterface`. This change makes the Guzzle interfaces compatible with
  the PSR-7 interfaces.
* `GuzzleHttp\Message\MessageFactory` no longer allows subclasses to add
  custom request options using double-dispatch (this was an implementation
  detail). Instead, you should now provide an associative array to the
  constructor which is a mapping of the request option name mapping to a
  function that applies the option value to a request.
* Removed the concept of "throwImmediately" from exceptions and error events.
  This control mechanism was used to stop a transfer of concurrent requests
  from completing. This can now be handled by throwing the exception or by
  cancelling a pool of requests or each outstanding future request individually.
* Updated to "GuzzleHttp\Streams" 3.0.
    * `GuzzleHttp\Stream\StreamInterface::getContents()` no longer accepts a
      `maxLen` parameter. This update makes the Guzzle streams project
      compatible with the current PSR-7 proposal.
    * `GuzzleHttp\Stream\Stream::__construct`,
      `GuzzleHttp\Stream\Stream::factory`, and
      `GuzzleHttp\Stream\Utils::create` no longer accept a size in the second
      argument. They now accept an associative array of options, including the
      "size" key and "metadata" key which can be used to provide custom metadata.

## 4.2.2 - 2014-09-08

* Fixed a memory leak in the CurlAdapter when reusing cURL handles.
* No longer using `request_fulluri` in stream adapter proxies.
* Relative redirects are now based on the last response, not the first response.

## 4.2.1 - 2014-08-19

* Ensuring that the StreamAdapter does not always add a Content-Type header
* Adding automated github releases with a phar and zip

## 4.2.0 - 2014-08-17

* Now merging in default options using a case-insensitive comparison.
  Closes https://github.com/guzzle/guzzle/issues/767
* Added the ability to automatically decode `Content-Encoding` response bodies
  using the `decode_content` request option. This is set to `true` by default
  to decode the response body if it comes over the wire with a
  `Content-Encoding`. Set this value to `false` to disable decoding the
  response content, and pass a string to provide a request `Accept-Encoding`
  header and turn on automatic response decoding. This feature now allows you
  to pass an `Accept-Encoding` header in the headers of a request but still
  disable automatic response decoding.
  Closes https://github.com/guzzle/guzzle/issues/764
* Added the ability to throw an exception immediately when transferring
  requests in parallel. Closes https://github.com/guzzle/guzzle/issues/760
* Updating guzzlehttp/streams dependency to ~2.1
* No longer utilizing the now deprecated namespaced methods from the stream
  package.

## 4.1.8 - 2014-08-14

* Fixed an issue in the CurlFactory that caused setting the `stream=false`
  request option to throw an exception.
  See: https://github.com/guzzle/guzzle/issues/769
* TransactionIterator now calls rewind on the inner iterator.
  See: https://github.com/guzzle/guzzle/pull/765
* You can now set the `Content-Type` header to `multipart/form-data`
  when creating POST requests to force multipart bodies.
  See https://github.com/guzzle/guzzle/issues/768

## 4.1.7 - 2014-08-07

* Fixed an error in the HistoryPlugin that caused the same request and response
  to be logged multiple times when an HTTP protocol error occurs.
* Ensuring that cURL does not add a default Content-Type when no Content-Type
  has been supplied by the user. This prevents the adapter layer from modifying
  the request that is sent over the wire after any listeners may have already
  put the request in a desired state (e.g., signed the request).
* Throwing an exception when you attempt to send requests that have the
  "stream" set to true in parallel using the MultiAdapter.
* Only calling curl_multi_select when there are active cURL handles. This was
  previously changed and caused performance problems on some systems due to PHP
  always selecting until the maximum select timeout.
* Fixed a bug where multipart/form-data POST fields were not correctly
  aggregated (e.g., values with "&").

## 4.1.6 - 2014-08-03

* Added helper methods to make it easier to represent messages as strings,
  including getting the start line and getting headers as a string.

## 4.1.5 - 2014-08-02

* Automatically retrying cURL "Connection died, retrying a fresh connect"
  errors when possible.
* cURL implementation cleanup
* Allowing multiple event subscriber listeners to be registered per event by
  passing an array of arrays of listener configuration.

## 4.1.4 - 2014-07-22

* Fixed a bug that caused multi-part POST requests with more than one field to
  serialize incorrectly.
* Paths can now be set to "0"
* `ResponseInterface::xml` now accepts a `libxml_options` option and added a
  missing default argument that was required when parsing XML response bodies.
* A `save_to` stream is now created lazily, which means that files are not
  created on disk unless a request succeeds.

## 4.1.3 - 2014-07-15

* Various fixes to multipart/form-data POST uploads
* Wrapping function.php in an if-statement to ensure Guzzle can be used
  globally and in a Composer install
* Fixed an issue with generating and merging in events to an event array
* POST headers are only applied before sending a request to allow you to change
  the query aggregator used before uploading
* Added much more robust query string parsing
* Fixed various parsing and normalization issues with URLs
* Fixing an issue where multi-valued headers were not being utilized correctly
  in the StreamAdapter

## 4.1.2 - 2014-06-18

## 4.1.0 - 2014-05-27

* Added a `json` request option to easily serialize JSON payloads.
* Added a `GuzzleHttp\json_decode()` wrapper to safely parse JSON.
* Added `setPort()` and `getPort()` to `GuzzleHttp\Message\RequestInterface`.
* Added the ability to provide an emitter to a client in the client constructor.
* Added the ability to persist a cookie session using $_SESSION.
* Added a trait that can be used to add event listeners to an iterator.
* Removed request method constants from RequestInterface.
* Fixed warning when invalid request start-lines are received.
* Updated MessageFactory to work with custom request option methods.
* Updated cacert bundle to latest build.

4.0.2 (2014-04-16)
------------------

* Proxy requests using the StreamAdapter now properly use request_fulluri (#632)
* Added the ability to set scalars as POST fields (#628)

## 4.0.1 - 2014-04-04

* The HTTP status code of a response is now set as the exception code of
  RequestException objects.
* 303 redirects will now correctly switch from POST to GET requests.
* The default parallel adapter of a client now correctly uses the MultiAdapter.
* HasDataTrait now initializes the internal data array as an empty array so
  that the toArray() method always returns an array.

## 4.0.0 - 2014-03-29

* For more information on the 4.0 transition, see:
  http://mtdowling.com/blog/2014/03/15/guzzle-4-rc/
* For information on changes and upgrading, see:
  https://github.com/guzzle/guzzle/blob/master/UPGRADING.md#3x-to-40
* Added `GuzzleHttp\batch()` as a convenience function for sending requests in
  parallel without needing to write asynchronous code.
* Restructured how events are added to `GuzzleHttp\ClientInterface::sendAll()`.
  You can now pass a callable or an array of associative arrays where each
  associative array contains the "fn", "priority", and "once" keys.

## 4.0.0.rc-2 - 2014-03-25

* Removed `getConfig()` and `setConfig()` from clients to avoid confusion
  around whether things like base_url, message_factory, etc. should be able to
  be retrieved or modified.
* Added `getDefaultOption()` and `setDefaultOption()` to ClientInterface
* functions.php functions were renamed using snake_case to match PHP idioms
* Added support for `HTTP_PROXY`, `HTTPS_PROXY`, and
  `GUZZLE_CURL_SELECT_TIMEOUT` environment variables
* Added the ability to specify custom `sendAll()` event priorities
* Added the ability to specify custom stream context options to the stream
  adapter.
* Added a functions.php function for `get_path()` and `set_path()`
* CurlAdapter and MultiAdapter now use a callable to generate curl resources
* MockAdapter now properly reads a body and emits a `headers` event
* Updated Url class to check if a scheme and host are set before adding ":"
  and "//". This allows empty Url (e.g., "") to be serialized as "".
* Parsing invalid XML no longer emits warnings
* Curl classes now properly throw AdapterExceptions
* Various performance optimizations
* Streams are created with the faster `Stream\create()` function
* Marked deprecation_proxy() as internal

  clobbering everything).
* Merging URLs will now use the query string object from the relative URL (thus allowing custom query aggregators)
* Query strings are now parsed in a way that they do no convert empty keys with no value to have a dangling `=`.
  For example `foo&bar=baz` is now correctly parsed and recognized as `foo&bar=baz` rather than `foo=&bar=baz`.
* Now properly escaping the regular expression delimiter when matching Cookie domains.
* Network access is now disabled when loading XML documents

## 3.7.0 - 2013-06-10

* See UPGRADING.md for more information on how to upgrade.
* Requests now support the ability to specify an array of $options when creating a request to more easily modify a
  request. You can pass a 'request.options' configuration setting to a client to apply default request options to
  every request created by a client (e.g. default query string variables, headers, curl options, etc.).
* Added a static facade class that allows you to use Guzzle with static methods and mount the class to `\Guzzle`.
  See `Guzzle\Http\StaticClient::mount`.
* Added `command.request_options` to `Guzzle\Service\Command\AbstractCommand` to pass request options to requests
      created by a command (e.g. custom headers, query string variables, timeout settings, etc.).
* Stream size in `Guzzle\Stream\PhpStreamRequestFactory` will now be set if Content-Length is returned in the
  headers of a response
* Added `Guzzle\Common\Collection::setPath($path, $value)` to set a value into an array using a nested key
  (e.g. `$collection->setPath('foo/baz/bar', 'test'); echo $collection['foo']['bar']['bar'];`)
* ServiceBuilders now support storing and retrieving arbitrary data
* CachePlugin can now purge all resources for a given URI
* CachePlugin can automatically purge matching cached items when a non-idempotent request is sent to a resource
* CachePlugin now uses the Vary header to determine if a resource is a cache hit
* `Guzzle\Http\Message\Response` now implements `\Serializable`
* Added `Guzzle\Cache\CacheAdapterFactory::fromCache()` to more easily create cache adapters
* `Guzzle\Service\ClientInterface::execute()` now accepts an array, single command, or Traversable
* Fixed a bug in `Guzzle\Http\Message\Header\Link::addLink()`
* Better handling of calculating the size of a stream in `Guzzle\Stream\Stream` using fstat() and caching the size
* `Guzzle\Common\Exception\ExceptionCollection` now creates a more readable exception message
* Fixing BC break: Added back the MonologLogAdapter implementation rather than extending from PsrLog so that older
  Symfony users can still use the old version of Monolog.
* Fixing BC break: Added the implementation back in for `Guzzle\Http\Message\AbstractMessage::getTokenizedHeader()`.

## 3.6.0 - 2013-05-29

* ServiceDescription now implements ToArrayInterface
* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters
* Guzzle can now correctly parse incomplete URLs
* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
  CacheControl header implementation.
* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate

* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
  directly via interfaces
* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
  but are a no-op until removed.
* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
  `Guzzle\Service\Command\ArrayCommandInterface`.
* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
  on a request while the request is still being transferred
* The ability to case-insensitively search for header values
* Guzzle\Http\Message\Header::hasExactHeader
* Guzzle\Http\Message\Header::raw. Use getAll()

* POST requests using a custom entity body are now treated exactly like PUT requests but with a custom cURL method. This
  means that the redirect behavior of POST requests with custom bodies will not be the same as POST requests that use
  POST fields or files (the latter is only used when emulating a form POST in the browser).
* Lots of cleanup to CurlHandle::factory and RequestFactory::createRequest

## 3.3.1 - 2013-03-10

  additional properties also support locations and can be used to parse JSON responses where the outermost part of the
  JSON is an array
* Added support for nested renaming of JSON models (rename sentAs to name)

# Guzzle, PHP HTTP client

[![Latest Version](https://img.shields.io/github/release/guzzle/guzzle.svg?style=flat-square)](https://github.com/guzzle/guzzle/releases)
[![Build Status](https://img.shields.io/github/workflow/status/guzzle/guzzle/CI?label=ci%20build&style=flat-square)](https://github.com/guzzle/guzzle/actions?query=workflow%3ACI)
[![Total Downloads](https://img.shields.io/packagist/dt/guzzlehttp/guzzle.svg?style=flat-square)](https://packagist.org/packages/guzzlehttp/guzzle)

Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
trivial to integrate with web services.

- Simple interface for building query strings, POST requests, streaming large
  uploads, streaming large downloads, using HTTP cookies, uploading JSON data,
  etc...
- Can send both synchronous and asynchronous requests using the same interface.
- Uses PSR-7 interfaces for requests, responses, and streams. This allows you
  to utilize other PSR-7 compatible libraries with Guzzle.
- Abstracts away the underlying HTTP transport, allowing you to write
  environment and transport agnostic code; i.e., no hard dependency on cURL,
  PHP streams, sockets, or non-blocking event loops.
- Middleware system allows you to augment and compose client behavior.

```php
$client = new \GuzzleHttp\Client();
$response = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle');

echo $response->getStatusCode(); # 200
echo $response->getHeaderLine('content-type'); # 'application/json; charset=utf8'
echo $response->getBody(); # '{"id": 1420053, "name": "guzzle", ...}'

# Send an asynchronous request.
$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
$promise = $client->sendAsync($request)->then(function ($response) {
    echo 'I completed! ' . $response->getBody();
});

$promise->wait();
```

## Help and docs

We use GitHub issues only to discuss bugs and new features. For support please refer to:

- [Documentation](https://docs.guzzlephp.org)
- [Stack Overflow](https://stackoverflow.com/questions/tagged/guzzle)
- [#guzzle](https://app.slack.com/client/T0D2S9JCT/CE6UAAKL4) channel on [PHP-HTTP Slack](https://slack.httplug.io/)
- [Gitter](https://gitter.im/guzzle/guzzle)


## Installing Guzzle

The recommended way to install Guzzle is through
[Composer](https://getcomposer.org/).

```bash
# Install Composer
curl -sS https://getcomposer.org/installer | php
```

Next, run the Composer command to install the latest stable version of Guzzle:

```bash
composer require guzzlehttp/guzzle
```

After installing, you need to require Composer's autoloader:

```php
require 'vendor/autoload.php';
```

You can then later update Guzzle using composer:

 ```bash
composer update
 ```

No system CA bundle could be found in any of the the common system locations.
PHP versions earlier than 5.6 are not properly configured to use the system's
CA bundle by default. In order to verify peer certificates, you will need to
supply the path on disk to a certificate bundle to the 'verify' request
option: http://docs.guzzlephp.org/en/latest/clients.html#verify. If you do not
need a specific certificate bundle, then Mozilla provides a commonly used CA
bundle which can be downloaded here (provided by the maintainer of cURL):
https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt. Once
you have a CA bundle available on disk, you can set the 'openssl.cafile' PHP
ini setting to point to the path to the file, allowing you to omit the 'verify'
request option. See http://curl.haxx.se/docs/sslcerts.html for more
information.

Guzzle Upgrade Guide
====================

5.0 to 6.0
----------

Guzzle now uses [PSR-7](http://www.php-fig.org/psr/psr-7/) for HTTP messages.
Due to the fact that these messages are immutable, this prompted a refactoring
of Guzzle to use a middleware based system rather than an event system. Any
HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be
updated to work with the new immutable PSR-7 request and response objects. Any
event listeners or subscribers need to be updated to become middleware
functions that wrap handlers (or are injected into a
`GuzzleHttp\HandlerStack`).

- Removed `GuzzleHttp\BatchResults`
- Removed `GuzzleHttp\Collection`
- Removed `GuzzleHttp\HasDataTrait`
- Removed `GuzzleHttp\ToArrayInterface`
- The `guzzlehttp/streams` dependency has been removed. Stream functionality
  is now present in the `GuzzleHttp\Psr7` namespace provided by the
  `guzzlehttp/psr7` package.
- Guzzle no longer uses ReactPHP promises and now uses the
  `guzzlehttp/promises` library. We use a custom promise library for three
  significant reasons:
  1. React promises (at the time of writing this) are recursive. Promise
     chaining and promise resolution will eventually blow the stack. Guzzle
     promises are not recursive as they use a sort of trampolining technique.
     Note: there has been movement in the React project to modify promises to
     no longer utilize recursion.
  2. Guzzle needs to have the ability to synchronously block on a promise to
     wait for a result. Guzzle promises allows this functionality (and does
     not require the use of recursion).
  3. Because we need to be able to wait on a result, doing so using React
     promises requires wrapping react promises with RingPHP futures. This
     overhead is no longer needed, reducing stack sizes, reducing complexity,
     and improving performance.
- `GuzzleHttp\Mimetypes` has been moved to a function in
  `GuzzleHttp\Psr7\mimetype_from_extension` and
  `GuzzleHttp\Psr7\mimetype_from_filename`.
- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query
  strings must now be passed into request objects as strings, or provided to
  the `query` request option when creating requests with clients. The `query`
  option uses PHP's `http_build_query` to convert an array to a string. If you
  need a different serialization technique, you will need to pass the query
  string in as a string. There are a couple helper functions that will make
  working with query strings easier: `GuzzleHttp\Psr7\parse_query` and
  `GuzzleHttp\Psr7\build_query`.
- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware
  system based on PSR-7, using RingPHP and it's middleware system as well adds
  more complexity than the benefits it provides. All HTTP handlers that were
  present in RingPHP have been modified to work directly with PSR-7 messages
  and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces
  complexity in Guzzle, removes a dependency, and improves performance. RingPHP
  will be maintained for Guzzle 5 support, but will no longer be a part of
  Guzzle 6.
- As Guzzle now uses a middleware based systems the event system and RingPHP
  integration has been removed. Note: while the event system has been removed,
  it is possible to add your own type of event system that is powered by the
  middleware system.
  - Removed the `Event` namespace.
  - Removed the `Subscriber` namespace.
  - Removed `Transaction` class
  - Removed `RequestFsm`
  - Removed `RingBridge`
  - `GuzzleHttp\Subscriber\Cookie` is now provided by
    `GuzzleHttp\Middleware::cookies`
  - `GuzzleHttp\Subscriber\HttpError` is now provided by
    `GuzzleHttp\Middleware::httpError`
  - `GuzzleHttp\Subscriber\History` is now provided by
    `GuzzleHttp\Middleware::history`
  - `GuzzleHttp\Subscriber\Mock` is now provided by
    `GuzzleHttp\Handler\MockHandler`
  - `GuzzleHttp\Subscriber\Prepare` is now provided by
    `GuzzleHttp\PrepareBodyMiddleware`
  - `GuzzleHttp\Subscriber\Redirect` is now provided by
    `GuzzleHttp\RedirectMiddleware`
- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in
  `GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone.
- Static functions in `GuzzleHttp\Utils` have been moved to namespaced
  functions under the `GuzzleHttp` namespace. This requires either a Composer
  based autoloader or you to include functions.php.
- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to
  `GuzzleHttp\ClientInterface::getConfig`.
- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed.
- The `json` and `xml` methods of response objects has been removed. With the
  migration to strictly adhering to PSR-7 as the interface for Guzzle messages,
  adding methods to message interfaces would actually require Guzzle messages
  to extend from PSR-7 messages rather then work with them directly.

## Migrating to middleware

The change to PSR-7 unfortunately required significant refactoring to Guzzle
due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event
system from plugins. The event system relied on mutability of HTTP messages and
side effects in order to work. With immutable messages, you have to change your
workflow to become more about either returning a value (e.g., functional
middlewares) or setting a value on an object. Guzzle v6 has chosen the
functional middleware approach.

Instead of using the event system to listen for things like the `before` event,
you now create a stack based middleware function that intercepts a request on
the way in and the promise of the response on the way out. This is a much
simpler and more predictable approach than the event system and works nicely
with PSR-7 middleware. Due to the use of promises, the middleware system is
also asynchronous.

v5:

```php
use GuzzleHttp\Event\BeforeEvent;
$client = new GuzzleHttp\Client();
// Get the emitter and listen to the before event.
$client->getEmitter()->on('before', function (BeforeEvent $e) {
    // Guzzle v5 events relied on mutation
    $e->getRequest()->setHeader('X-Foo', 'Bar');
});
```

v6:

In v6, you can modify the request before it is sent using the `mapRequest`
middleware. The idiomatic way in v6 to modify the request/response lifecycle is
to setup a handler middleware stack up front and inject the handler into a
client.

```php
use GuzzleHttp\Middleware;
// Create a handler stack that has all of the default middlewares attached
$handler = GuzzleHttp\HandlerStack::create();
// Push the handler onto the handler stack
$handler->push(Middleware::mapRequest(function (RequestInterface $request) {
    // Notice that we have to return a request object
    return $request->withHeader('X-Foo', 'Bar');
}));
// Inject the handler into the client
$client = new GuzzleHttp\Client(['handler' => $handler]);
```

## POST Requests

This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params)
and `multipart` request options. `form_params` is an associative array of
strings or array of strings and is used to serialize an
`application/x-www-form-urlencoded` POST request. The
[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart)
option is now used to send a multipart/form-data POST request.

`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add
POST files to a multipart/form-data request.

The `body` option no longer accepts an array to send POST requests. Please use
`multipart` or `form_params` instead.

The `base_url` option has been renamed to `base_uri`.

4.x to 5.0
----------

## Rewritten Adapter Layer

Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send
HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor
is still supported, but it has now been renamed to `handler`. Instead of
passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP
`callable` that follows the RingPHP specification.

## Removed Fluent Interfaces

[Fluent interfaces were removed](http://ocramius.github.io/blog/fluent-interfaces-are-evil)
from the following classes:

- `GuzzleHttp\Collection`
- `GuzzleHttp\Url`
- `GuzzleHttp\Query`
- `GuzzleHttp\Post\PostBody`
- `GuzzleHttp\Cookie\SetCookie`

## Removed functions.php

Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following
functions can be used as replacements.

- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode`
- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath`
- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path`
- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however,
  deprecated in favor of using `GuzzleHttp\Pool::batch()`.

The "procedural" global client has been removed with no replacement (e.g.,
`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client`
object as a replacement.

## `throwImmediately` has been removed

The concept of "throwImmediately" has been removed from exceptions and error
events. This control mechanism was used to stop a transfer of concurrent
requests from completing. This can now be handled by throwing the exception or
by cancelling a pool of requests or each outstanding future request
individually.

## headers event has been removed

Removed the "headers" event. This event was only useful for changing the
body a response once the headers of the response were known. You can implement
a similar behavior in a number of ways. One example might be to use a
FnStream that has access to the transaction being sent. For example, when the
first byte is written, you could check if the response headers match your
expectations, and if so, change the actual stream body that is being
written to.

## Updates to HTTP Messages

Removed the `asArray` parameter from
`GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
value as an array, then use the newly added `getHeaderAsArray()` method of
`MessageInterface`. This change makes the Guzzle interfaces compatible with
the PSR-7 interfaces.

3.x to 4.0
----------

## Overarching changes:

- Now requires PHP 5.4 or greater.
- No longer requires cURL to send requests.
- Guzzle no longer wraps every exception it throws. Only exceptions that are
  recoverable are now wrapped by Guzzle.
- Various namespaces have been removed or renamed.
- No longer requiring the Symfony EventDispatcher. A custom event dispatcher
  based on the Symfony EventDispatcher is
  now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant
  speed and functionality improvements).

Changes per Guzzle 3.x namespace are described below.

## Batch

The `Guzzle\Batch` namespace has been removed. This is best left to
third-parties to implement on top of Guzzle's core HTTP library.

## Cache

The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement
has been implemented yet, but hoping to utilize a PSR cache interface).

## Common

- Removed all of the wrapped exceptions. It's better to use the standard PHP
  library for unrecoverable exceptions.
- `FromConfigInterface` has been removed.
- `Guzzle\Common\Version` has been removed. The VERSION constant can be found
  at `GuzzleHttp\ClientInterface::VERSION`.

### Collection

- `getAll` has been removed. Use `toArray` to convert a collection to an array.
- `inject` has been removed.
- `keySearch` has been removed.
- `getPath` no longer supports wildcard expressions. Use something better like
  JMESPath for this.
- `setPath` now supports appending to an existing array via the `[]` notation.

### Events

Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses
`GuzzleHttp\Event\Emitter`.

- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by
  `GuzzleHttp\Event\EmitterInterface`.
- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by
  `GuzzleHttp\Event\Emitter`.
- `Symfony\Component\EventDispatcher\Event` is replaced by
  `GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in
  `GuzzleHttp\Event\EventInterface`.
- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and
  `HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the
  event emitter of a request, client, etc. now uses the `getEmitter` method
  rather than the `getDispatcher` method.

#### Emitter

- Use the `once()` method to add a listener that automatically removes itself
  the first time it is invoked.
- Use the `listeners()` method to retrieve a list of event listeners rather than
  the `getListeners()` method.
- Use `emit()` instead of `dispatch()` to emit an event from an emitter.
- Use `attach()` instead of `addSubscriber()` and `detach()` instead of
  `removeSubscriber()`.

```php
$mock = new Mock();
// 3.x
$request->getEventDispatcher()->addSubscriber($mock);
$request->getEventDispatcher()->removeSubscriber($mock);
// 4.x
$request->getEmitter()->attach($mock);
$request->getEmitter()->detach($mock);
```

Use the `on()` method to add a listener rather than the `addListener()` method.

```php
// 3.x
$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } );
// 4.x
$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } );
```

## Http

### General changes

- The cacert.pem certificate has been moved to `src/cacert.pem`.
- Added the concept of adapters that are used to transfer requests over the
  wire.
- Simplified the event system.
- Sending requests in parallel is still possible, but batching is no longer a
  concept of the HTTP layer. Instead, you must use the `complete` and `error`
  events to asynchronously manage parallel request transfers.
- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`.
- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`.
- QueryAggregators have been rewritten so that they are simply callable
  functions.
- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in
  `functions.php` for an easy to use static client instance.
- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from
  `GuzzleHttp\Exception\TransferException`.

### Client

Calling methods like `get()`, `post()`, `head()`, etc. no longer create and
return a request, but rather creates a request, sends the request, and returns
the response.

```php
// 3.0
$request = $client->get('/');
$response = $request->send();

// 4.0
$response = $client->get('/');

// or, to mirror the previous behavior
$request = $client->createRequest('GET', '/');
$response = $client->send($request);
```

`GuzzleHttp\ClientInterface` has changed.

- The `send` method no longer accepts more than one request. Use `sendAll` to
  send multiple requests in parallel.
- `setUserAgent()` has been removed. Use a default request option instead. You
  could, for example, do something like:
  `$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`.
- `setSslVerification()` has been removed. Use default request options instead,
  like `$client->setConfig('defaults/verify', true)`.

`GuzzleHttp\Client` has changed.

- The constructor now accepts only an associative array. You can include a
  `base_url` string or array to use a URI template as the base URL of a client.
  You can also specify a `defaults` key that is an associative array of default
  request options. You can pass an `adapter` to use a custom adapter,
  `batch_adapter` to use a custom adapter for sending requests in parallel, or
  a `message_factory` to change the factory used to create HTTP requests and
  responses.
- The client no longer emits a `client.create_request` event.
- Creating requests with a client no longer automatically utilize a URI
  template. You must pass an array into a creational method (e.g.,
  `createRequest`, `get`, `put`, etc.) in order to expand a URI template.

### Messages

Messages no longer have references to their counterparts (i.e., a request no
longer has a reference to it's response, and a response no loger has a
reference to its request). This association is now managed through a
`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to
these transaction objects using request events that are emitted over the
lifecycle of a request.

#### Requests with a body

- `GuzzleHttp\Message\EntityEnclosingRequest` and
  `GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The
  separation between requests that contain a body and requests that do not
  contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface`
  handles both use cases.
- Any method that previously accepts a `GuzzleHttp\Response` object now accept a
  `GuzzleHttp\Message\ResponseInterface`.
- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to
  `GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create
  both requests and responses and is implemented in
  `GuzzleHttp\Message\MessageFactory`.
- POST field and file methods have been removed from the request object. You
  must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface`
  to control the format of a POST body. Requests that are created using a
  standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use
  a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if
  the method is POST and no body is provided.

```php
$request = $client->createRequest('POST', '/');
$request->getBody()->setField('foo', 'bar');
$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r')));
```

#### Headers

- `GuzzleHttp\Message\Header` has been removed. Header values are now simply
  represented by an array of values or as a string. Header values are returned
  as a string by default when retrieving a header value from a message. You can
  pass an optional argument of `true` to retrieve a header value as an array
  of strings instead of a single concatenated string.
- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to
  `GuzzleHttp\Post`. This interface has been simplified and now allows the
  addition of arbitrary headers.
- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most
  of the custom headers are now handled separately in specific
  subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has
  been updated to properly handle headers that contain parameters (like the
  `Link` header).

#### Responses

- `GuzzleHttp\Message\Response::getInfo()` and
  `GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event
  system to retrieve this type of information.
- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed.
- `GuzzleHttp\Message\Response::getMessage()` has been removed.
- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific
  methods have moved to the CacheSubscriber.
- Header specific helper functions like `getContentMd5()` have been removed.
  Just use `getHeader('Content-MD5')` instead.
- `GuzzleHttp\Message\Response::setRequest()` and
  `GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event
  system to work with request and response objects as a transaction.
- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the
  Redirect subscriber instead.
- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have
  been removed. Use `getStatusCode()` instead.

#### Streaming responses

Streaming requests can now be created by a client directly, returning a
`GuzzleHttp\Message\ResponseInterface` object that contains a body stream
referencing an open PHP HTTP stream.

```php
// 3.0
use Guzzle\Stream\PhpStreamRequestFactory;
$request = $client->get('/');
$factory = new PhpStreamRequestFactory();
$stream = $factory->fromRequest($request);
$data = $stream->read(1024);

// 4.0
$response = $client->get('/', ['stream' => true]);
// Read some data off of the stream in the response body
$data = $response->getBody()->read(1024);
```

#### Redirects

The `configureRedirects()` method has been removed in favor of a
`allow_redirects` request option.

```php
// Standard redirects with a default of a max of 5 redirects
$request = $client->createRequest('GET', '/', ['allow_redirects' => true]);

// Strict redirects with a custom number of redirects
$request = $client->createRequest('GET', '/', [
    'allow_redirects' => ['max' => 5, 'strict' => true]
]);
```

#### EntityBody

EntityBody interfaces and classes have been removed or moved to
`GuzzleHttp\Stream`. All classes and interfaces that once required
`GuzzleHttp\EntityBodyInterface` now require
`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no
longer uses `GuzzleHttp\EntityBody::factory` but now uses
`GuzzleHttp\Stream\Stream::factory` or even better:
`GuzzleHttp\Stream\create()`.

- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface`
- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream`
- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream`
- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream`
- `Guzzle\Http\IoEmittyinEntityBody` has been removed.

#### Request lifecycle events

Requests previously submitted a large number of requests. The number of events
emitted over the lifecycle of a request has been significantly reduced to make
it easier to understand how to extend the behavior of a request. All events
emitted during the lifecycle of a request now emit a custom
`GuzzleHttp\Event\EventInterface` object that contains context providing
methods and a way in which to modify the transaction at that specific point in
time (e.g., intercept the request and set a response on the transaction).

- `request.before_send` has been renamed to `before` and now emits a
  `GuzzleHttp\Event\BeforeEvent`
- `request.complete` has been renamed to `complete` and now emits a
  `GuzzleHttp\Event\CompleteEvent`.
- `request.sent` has been removed. Use `complete`.
- `request.success` has been removed. Use `complete`.
- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`.
- `request.exception` has been removed. Use `error`.
- `request.receive.status_line` has been removed.
- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to
  maintain a status update.
- `curl.callback.write` has been removed. Use a custom `StreamInterface` to
  intercept writes.
- `curl.callback.read` has been removed. Use a custom `StreamInterface` to
  intercept reads.

`headers` is a new event that is emitted after the response headers of a
request have been received before the body of the response is downloaded. This
event emits a `GuzzleHttp\Event\HeadersEvent`.

You can intercept a request and inject a response using the `intercept()` event
of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and
`GuzzleHttp\Event\ErrorEvent` event.

See: http://docs.guzzlephp.org/en/latest/events.html

## Inflection

The `Guzzle\Inflection` namespace has been removed. This is not a core concern
of Guzzle.

## Iterator

The `Guzzle\Iterator` namespace has been removed.

- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and
  `Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of
  Guzzle itself.
- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent
  class is shipped with PHP 5.4.
- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because
  it's easier to just wrap an iterator in a generator that maps values.

For a replacement of these iterators, see https://github.com/nikic/iter

## Log

The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The
`Guzzle\Log` namespace has been removed. Guzzle now relies on
`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been
moved to `GuzzleHttp\Subscriber\Log\Formatter`.

## Parser

The `Guzzle\Parser` namespace has been removed. This was previously used to
make it possible to plug in custom parsers for cookies, messages, URI
templates, and URLs; however, this level of complexity is not needed in Guzzle
so it has been removed.

- Cookie: Cookie parsing logic has been moved to
  `GuzzleHttp\Cookie\SetCookie::fromString`.
- Message: Message parsing logic for both requests and responses has been moved
  to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only
  used in debugging or deserializing messages, so it doesn't make sense for
  Guzzle as a library to add this level of complexity to parsing messages.
- UriTemplate: URI template parsing has been moved to
  `GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL
  URI template library if it is installed.
- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously
  it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary,
  then developers are free to subclass `GuzzleHttp\Url`.

## Plugin

The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`.
Several plugins are shipping with the core Guzzle library under this namespace.

- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar
  code has moved to `GuzzleHttp\Cookie`.
- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin.
- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is
  received.
- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin.
- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before
  sending. This subscriber is attached to all requests by default.
- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin.

The following plugins have been removed (third-parties are free to re-implement
these if needed):

- `GuzzleHttp\Plugin\Async` has been removed.
- `GuzzleHttp\Plugin\CurlAuth` has been removed.
- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This
  functionality should instead be implemented with event listeners that occur
  after normal response parsing occurs in the guzzle/command package.

The following plugins are not part of the core Guzzle package, but are provided
in separate repositories:

- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler
  to build custom retry policies using simple functions rather than various
  chained classes. See: https://github.com/guzzle/retry-subscriber
- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to
  https://github.com/guzzle/cache-subscriber
- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to
  https://github.com/guzzle/log-subscriber
- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to
  https://github.com/guzzle/message-integrity-subscriber
- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to
  `GuzzleHttp\Subscriber\MockSubscriber`.
- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to
  https://github.com/guzzle/oauth-subscriber

## Service

The service description layer of Guzzle has moved into two separate packages:

- http://github.com/guzzle/command Provides a high level abstraction over web
  services by representing web service operations using commands.
- http://github.com/guzzle/guzzle-services Provides an implementation of
  guzzle/command that provides request serialization and response parsing using
  Guzzle service descriptions.

## Stream

Stream have moved to a separate package available at
https://github.com/guzzle/streams.

`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take
on the responsibilities of `Guzzle\Http\EntityBody` and
`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number
of methods implemented by the `StreamInterface` has been drastically reduced to
allow developers to more easily extend and decorate stream behavior.

## Removed methods from StreamInterface

- `getStream` and `setStream` have been removed to better encapsulate streams.
- `getMetadata` and `setMetadata` have been removed in favor of
  `GuzzleHttp\Stream\MetadataStreamInterface`.
- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been
  removed. This data is accessible when
  using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`.
- `rewind` has been removed. Use `seek(0)` for a similar behavior.

## Renamed methods

- `detachStream` has been renamed to `detach`.
- `feof` has been renamed to `eof`.
- `ftell` has been renamed to `tell`.
- `readLine` has moved from an instance method to a static class method of
  `GuzzleHttp\Stream\Stream`.

## Metadata streams

`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams
that contain additional metadata accessible via `getMetadata()`.
`GuzzleHttp\Stream\StreamInterface::getMetadata` and
`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed.

## StreamRequestFactory

The entire concept of the StreamRequestFactory has been removed. The way this
was used in Guzzle 3 broke the actual interface of sending streaming requests
(instead of getting back a Response, you got a StreamInterface). Streaming
PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`.

3.6 to 3.7
----------

### Deprecations

- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.:

```php
\Guzzle\Common\Version::$emitWarnings = true;
```

The following APIs and options have been marked as deprecated:

- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$request->getResponseBody()->isRepeatable()` instead.
- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
- Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
- Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
- Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
- Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
- Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
- Marked `Guzzle\Common\Collection::inject()` as deprecated.
- Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use
  `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or
  `$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));`

3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational
request methods. When paired with a client's configuration settings, these options allow you to specify default settings
for various aspects of a request. Because these options make other previous configuration options redundant, several
configuration options and methods of a client and AbstractCommand have been deprecated.

- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`.
- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`.
- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')`
- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0

        $command = $client->getCommand('foo', array(
            'command.headers' => array('Test' => '123'),
            'command.response_body' => '/path/to/file'
        ));

        // Should be changed to:

        $command = $client->getCommand('foo', array(
            'command.request_options' => array(
                'headers' => array('Test' => '123'),
                'save_as' => '/path/to/file'
            )
        ));

### Interface changes

Additions and changes (you will need to update any implementations or subclasses you may have created):

- Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
  createRequest, head, delete, put, patch, post, options, prepareRequest
- Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
- Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
- Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
- Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
  default `array()`
- Added `Guzzle\Stream\StreamInterface::isRepeatable`
- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.

The following methods were removed from interfaces. All of these methods are still available in the concrete classes
that implement them, but you should update your code to use alternative methods:

- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
  `$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
  `$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or
  `$client->setDefaultOption('headers/{header_name}', 'value')`. or
  `$client->setDefaultOption('headers', array('header_name' => 'value'))`.
- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`.
- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail.
- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail.
- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail.
- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin.
- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin.
- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin.

### Cache plugin breaking changes

- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
  CacheStorageInterface. These two objects and interface will be removed in a future version.
- Always setting X-cache headers on cached responses
- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
  $request, Response $response);`
- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
- Added `CacheStorageInterface::purge($url)`
- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
  CanCacheStrategyInterface $canCache = null)`
- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`

3.5 to 3.6
----------

* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
  For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader().
  Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request.
* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
  CacheControl header implementation.
* Moved getLinks() from Response to just be used on a Link header object.

If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the
HeaderInterface (e.g. toArray(), getAll(), etc.).

### Interface changes

* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
  Guzzle\Http\Curl\RequestMediator
* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()

### Removed deprecated functions

* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().

### Deprecations

* The ability to case-insensitively search for header values
* Guzzle\Http\Message\Header::hasExactHeader
* Guzzle\Http\Message\Header::raw. Use getAll()
* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
  instead.

### Other changes

* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
  directly via interfaces
* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
  but are a no-op until removed.
* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
  `Guzzle\Service\Command\ArrayCommandInterface`.
* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
  on a request while the request is still being transferred
* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess

3.3 to 3.4
----------

Base URLs of a client now follow the rules of http://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs.

3.2 to 3.3
----------

### Response::getEtag() quote stripping removed

`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header

### Removed `Guzzle\Http\Utils`

The `Guzzle\Http\Utils` class was removed. This class was only used for testing.

### Stream wrapper and type

`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getStreamType()` are no longer converted to lowercase.

### curl.emit_io became emit_io

Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the
'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'

3.1 to 3.2
----------

### CurlMulti is no longer reused globally

Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added
to a single client can pollute requests dispatched from other clients.

If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the
ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is
created.

```php
$multi = new Guzzle\Http\Curl\CurlMulti();
$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json');
$builder->addListener('service_builder.create_client', function ($event) use ($multi) {
    $event['client']->setCurlMulti($multi);
}
});
```

### No default path

URLs no longer have a default path value of '/' if no path was specified.

Before:

```php
$request = $client->get('http://www.foo.com');
echo $request->getUrl();
// >> http://www.foo.com/
```

After:

```php
$request = $client->get('http://www.foo.com');
echo $request->getUrl();
// >> http://www.foo.com
```

### Less verbose BadResponseException

The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and
response information. You can, however, get access to the request and response object by calling `getRequest()` or
`getResponse()` on the exception object.

### Query parameter aggregation

Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a
setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is
responsible for handling the aggregation of multi-valued query string variables into a flattened hash.

2.8 to 3.x
----------

### Guzzle\Service\Inspector

Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig`

**Before**

```php
use Guzzle\Service\Inspector;

class YourClient extends \Guzzle\Service\Client
{
    public static function factory($config = array())
    {
        $default = array();
        $required = array('base_url', 'username', 'api_key');
        $config = Inspector::fromConfig($config, $default, $required);

        $client = new self(
            $config->get('base_url'),
            $config->get('username'),
            $config->get('api_key')
        );
        $client->setConfig($config);

        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));

        return $client;
    }
```

**After**

```php
use Guzzle\Common\Collection;

class YourClient extends \Guzzle\Service\Client
{
    public static function factory($config = array())
    {
        $default = array();
        $required = array('base_url', 'username', 'api_key');
        $config = Collection::fromConfig($config, $default, $required);

        $client = new self(
            $config->get('base_url'),
            $config->get('username'),
            $config->get('api_key')
        );
        $client->setConfig($config);

        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));

        return $client;
    }
```

### Guzzle\Service\Description\ServiceDescription

Commands are now called Operations

**Before**

```php
use Guzzle\Service\Description\ServiceDescription;

$sd = new ServiceDescription();
$sd->getCommands();     // @returns ApiCommandInterface[]
$sd->hasCommand($name);
$sd->getCommand($name); // @returns ApiCommandInterface|null
$sd->addCommand($command); // @param ApiCommandInterface $command
```

**After**

```php
use Guzzle\Service\Description\ServiceDescription;

$sd = new ServiceDescription();
$sd->getOperations();           // @returns OperationInterface[]
$sd->hasOperation($name);
$sd->getOperation($name);       // @returns OperationInterface|null
$sd->addOperation($operation);  // @param OperationInterface $operation
```

### Guzzle\Common\Inflection\Inflector

Namespace is now `Guzzle\Inflection\Inflector`

### Guzzle\Http\Plugin

Namespace is now `Guzzle\Plugin`. Many other changes occur within this namespace and are detailed in their own sections below.

### Guzzle\Http\Plugin\LogPlugin and Guzzle\Common\Log

Now `Guzzle\Plugin\Log\LogPlugin` and `Guzzle\Log` respectively.

**Before**

```php
use Guzzle\Common\Log\ClosureLogAdapter;
use Guzzle\Http\Plugin\LogPlugin;

/** @var \Guzzle\Http\Client */
$client;

// $verbosity is an integer indicating desired message verbosity level
$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $verbosity = LogPlugin::LOG_VERBOSE);
```

**After**

```php
use Guzzle\Log\ClosureLogAdapter;
use Guzzle\Log\MessageFormatter;
use Guzzle\Plugin\Log\LogPlugin;

/** @var \Guzzle\Http\Client */
$client;

// $format is a string indicating desired message format -- @see MessageFormatter
$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $format = MessageFormatter::DEBUG_FORMAT);
```

### Guzzle\Http\Plugin\CurlAuthPlugin

Now `Guzzle\Plugin\CurlAuth\CurlAuthPlugin`.

### Guzzle\Http\Plugin\ExponentialBackoffPlugin

Now `Guzzle\Plugin\Backoff\BackoffPlugin`, and other changes.

**Before**

```php
use Guzzle\Http\Plugin\ExponentialBackoffPlugin;

$backoffPlugin = new ExponentialBackoffPlugin($maxRetries, array_merge(
        ExponentialBackoffPlugin::getDefaultFailureCodes(), array(429)
    ));

$client->addSubscriber($backoffPlugin);
```

**After**

```php
use Guzzle\Plugin\Backoff\BackoffPlugin;
use Guzzle\Plugin\Backoff\HttpBackoffStrategy;

// Use convenient factory method instead -- see implementation for ideas of what
// you can do with chaining backoff strategies
$backoffPlugin = BackoffPlugin::getExponentialBackoff($maxRetries, array_merge(
        HttpBackoffStrategy::getDefaultFailureCodes(), array(429)
    ));
$client->addSubscriber($backoffPlugin);
```

### Known Issues

#### [BUG] Accept-Encoding header behavior changed unintentionally.

(See #217) (Fixed in 09daeb8c666fb44499a0646d655a8ae36456575e)

In version 2.8 setting the `Accept-Encoding` header would set the CURLOPT_ENCODING option, which permitted cURL to
properly handle gzip/deflate compressed responses from the server. In versions affected by this bug this does not happen.
See issue #217 for a workaround, or use a version containing the fix.

# Guzzle Promises

[Promises/A+](https://promisesaplus.com/) implementation that handles promise
chaining and resolution iteratively, allowing for "infinite" promise chaining
while keeping the stack size constant. Read [this blog post](https://blog.domenic.me/youre-missing-the-point-of-promises/)
for a general introduction to promises.

## Features

- [Promises/A+](https://promisesaplus.com/) implementation.
- Promise resolution and chaining is handled iteratively, allowing for
  "infinite" promise chaining.
- Promises have a synchronous `wait` method.
- Promises can be cancelled.
- Works with any object that has a `then` function.
- C# style async/await coroutine promises using
  `GuzzleHttp\Promise\Coroutine::of()`.


## Quick Start

A *promise* represents the eventual result of an asynchronous operation. The
primary way of interacting with a promise is through its `then` method, which
registers callbacks to receive either a promise's eventual value or the reason
why the promise cannot be fulfilled.

### Callbacks

Callbacks are registered with the `then` method by providing an optional 
`$onFulfilled` followed by an optional `$onRejected` function.


```php
use GuzzleHttp\Promise\Promise;

$promise = new Promise();
$promise->then(
    // $onFulfilled
    function ($value) {
        echo 'The promise was fulfilled.';
    },
    // $onRejected
    function ($reason) {
        echo 'The promise was rejected.';
    }
);
```

*Resolving* a promise means that you either fulfill a promise with a *value* or
reject a promise with a *reason*. Resolving a promise triggers callbacks
registered with the promise's `then` method. These callbacks are triggered
only once and in the order in which they were added.

### Resolving a Promise

Promises are fulfilled using the `resolve($value)` method. Resolving a promise
with any value other than a `GuzzleHttp\Promise\RejectedPromise` will trigger
all of the onFulfilled callbacks (resolving a promise with a rejected promise
will reject the promise and trigger the `$onRejected` callbacks).

```php
use GuzzleHttp\Promise\Promise;

$promise = new Promise();
$promise
    ->then(function ($value) {
        // Return a value and don't break the chain
        return "Hello, " . $value;
    })
    // This then is executed after the first then and receives the value
    // returned from the first then.
    ->then(function ($value) {
        echo $value;
    });

// Resolving the promise triggers the $onFulfilled callbacks and outputs
// "Hello, reader."
$promise->resolve('reader.');
```

### Promise Forwarding

Promises can be chained one after the other. Each then in the chain is a new
promise. The return value of a promise is what's forwarded to the next
promise in the chain. Returning a promise in a `then` callback will cause the
subsequent promises in the chain to only be fulfilled when the returned promise
has been fulfilled. The next promise in the chain will be invoked with the
resolved value of the promise.

```php
use GuzzleHttp\Promise\Promise;

$promise = new Promise();
$nextPromise = new Promise();

$promise
    ->then(function ($value) use ($nextPromise) {
        echo $value;
        return $nextPromise;
    })
    ->then(function ($value) {
        echo $value;
    });

// Triggers the first callback and outputs "A"
$promise->resolve('A');
// Triggers the second callback and outputs "B"
$nextPromise->resolve('B');
```

### Promise Rejection

When a promise is rejected, the `$onRejected` callbacks are invoked with the
rejection reason.

```php
use GuzzleHttp\Promise\Promise;

$promise = new Promise();
$promise->then(null, function ($reason) {
    echo $reason;
});

$promise->reject('Error!');
// Outputs "Error!"
```

### Rejection Forwarding

If an exception is thrown in an `$onRejected` callback, subsequent
`$onRejected` callbacks are invoked with the thrown exception as the reason.

```php
use GuzzleHttp\Promise\Promise;

$promise = new Promise();
$promise->then(null, function ($reason) {
    throw new Exception($reason);
})->then(null, function ($reason) {
    assert($reason->getMessage() === 'Error!');
});

$promise->reject('Error!');
```

You can also forward a rejection down the promise chain by returning a
`GuzzleHttp\Promise\RejectedPromise` in either an `$onFulfilled` or
`$onRejected` callback.

```php
use GuzzleHttp\Promise\Promise;
use GuzzleHttp\Promise\RejectedPromise;

$promise = new Promise();
$promise->then(null, function ($reason) {
    return new RejectedPromise($reason);
})->then(null, function ($reason) {
    assert($reason === 'Error!');
});

$promise->reject('Error!');
```

If an exception is not thrown in a `$onRejected` callback and the callback
does not return a rejected promise, downstream `$onFulfilled` callbacks are
invoked using the value returned from the `$onRejected` callback.

```php
use GuzzleHttp\Promise\Promise;

$promise = new Promise();
$promise
    ->then(null, function ($reason) {
        return "It's ok";
    })
    ->then(function ($value) {
        assert($value === "It's ok");
    });

$promise->reject('Error!');
```


## Synchronous Wait

You can synchronously force promises to complete using a promise's `wait`
method. When creating a promise, you can provide a wait function that is used
to synchronously force a promise to complete. When a wait function is invoked
it is expected to deliver a value to the promise or reject the promise. If the
wait function does not deliver a value, then an exception is thrown. The wait
function provided to a promise constructor is invoked when the `wait` function
of the promise is called.

```php
$promise = new Promise(function () use (&$promise) {
    $promise->resolve('foo');
});

// Calling wait will return the value of the promise.
echo $promise->wait(); // outputs "foo"
```

If an exception is encountered while invoking the wait function of a promise,
the promise is rejected with the exception and the exception is thrown.

```php
$promise = new Promise(function () use (&$promise) {
    throw new Exception('foo');
});

$promise->wait(); // throws the exception.
```

Calling `wait` on a promise that has been fulfilled will not trigger the wait
function. It will simply return the previously resolved value.

```php
$promise = new Promise(function () { die('this is not called!'); });
$promise->resolve('foo');
echo $promise->wait(); // outputs "foo"
```

Calling `wait` on a promise that has been rejected will throw an exception. If
the rejection reason is an instance of `\Exception` the reason is thrown.
Otherwise, a `GuzzleHttp\Promise\RejectionException` is thrown and the reason
can be obtained by calling the `getReason` method of the exception.

```php
$promise = new Promise();
$promise->reject('foo');
$promise->wait();
```

> PHP Fatal error:  Uncaught exception 'GuzzleHttp\Promise\RejectionException' with message 'The promise was rejected with value: foo'

### Unwrapping a Promise

When synchronously waiting on a promise, you are joining the state of the
promise into the current state of execution (i.e., return the value of the
promise if it was fulfilled or throw an exception if it was rejected). This is
called "unwrapping" the promise. Waiting on a promise will by default unwrap
the promise state.

You can force a promise to resolve and *not* unwrap the state of the promise
by passing `false` to the first argument of the `wait` function:

```php
$promise = new Promise();
$promise->reject('foo');
// This will not throw an exception. It simply ensures the promise has
// been resolved.
$promise->wait(false);
```

When unwrapping a promise, the resolved value of the promise will be waited
upon until the unwrapped value is not a promise. This means that if you resolve
promise A with a promise B and unwrap promise A, the value returned by the
wait function will be the value delivered to promise B.

**Note**: when you do not unwrap the promise, no value is returned.


## Cancellation

You can cancel a promise that has not yet been fulfilled using the `cancel()`
method of a promise. When creating a promise you can provide an optional
cancel function that when invoked cancels the action of computing a resolution
of the promise.


## API

### Promise

When creating a promise object, you can provide an optional `$waitFn` and
`$cancelFn`. `$waitFn` is a function that is invoked with no arguments and is
expected to resolve the promise. `$cancelFn` is a function with no arguments
that is expected to cancel the computation of a promise. It is invoked when the
`cancel()` method of a promise is called.

```php
use GuzzleHttp\Promise\Promise;

$promise = new Promise(
    function () use (&$promise) {
        $promise->resolve('waited');
    },
    function () {
        // do something that will cancel the promise computation (e.g., close
        // a socket, cancel a database query, etc...)
    }
);

assert('waited' === $promise->wait());
```

A promise has the following methods:

- `then(callable $onFulfilled, callable $onRejected) : PromiseInterface`
  
  Appends fulfillment and rejection handlers to the promise, and returns a new promise resolving to the return value of the called handler.

- `otherwise(callable $onRejected) : PromiseInterface`
  
  Appends a rejection handler callback to the promise, and returns a new promise resolving to the return value of the callback if it is called, or to its original fulfillment value if the promise is instead fulfilled.

- `wait($unwrap = true) : mixed`

  Synchronously waits on the promise to complete.
  
  `$unwrap` controls whether or not the value of the promise is returned for a
  fulfilled promise or if an exception is thrown if the promise is rejected.
  This is set to `true` by default.

- `cancel()`

  Attempts to cancel the promise if possible. The promise being cancelled and
  the parent most ancestor that has not yet been resolved will also be
  cancelled. Any promises waiting on the cancelled promise to resolve will also
  be cancelled.

- `getState() : string`

  Returns the state of the promise. One of `pending`, `fulfilled`, or
  `rejected`.

- `resolve($value)`

  Fulfills the promise with the given `$value`.

- `reject($reason)`

  Rejects the promise with the given `$reason`.


### FulfilledPromise

A fulfilled promise can be created to represent a promise that has been
fulfilled.

```php
use GuzzleHttp\Promise\FulfilledPromise;

$promise = new FulfilledPromise('value');

// Fulfilled callbacks are immediately invoked.
$promise->then(function ($value) {
    echo $value;
});
```


### RejectedPromise

A rejected promise can be created to represent a promise that has been
rejected.

```php
use GuzzleHttp\Promise\RejectedPromise;

$promise = new RejectedPromise('Error');

// Rejected callbacks are immediately invoked.
$promise->then(null, function ($reason) {
    echo $reason;
});
```


## Promise Interoperability

This library works with foreign promises that have a `then` method. This means
you can use Guzzle promises with [React promises](https://github.com/reactphp/promise)
for example. When a foreign promise is returned inside of a then method
callback, promise resolution will occur recursively.

```php
// Create a React promise
$deferred = new React\Promise\Deferred();
$reactPromise = $deferred->promise();

// Create a Guzzle promise that is fulfilled with a React promise.
$guzzlePromise = new GuzzleHttp\Promise\Promise();
$guzzlePromise->then(function ($value) use ($reactPromise) {
    // Do something something with the value...
    // Return the React promise
    return $reactPromise;
});
```

Please note that wait and cancel chaining is no longer possible when forwarding
a foreign promise. You will need to wrap a third-party promise with a Guzzle
promise in order to utilize wait and cancel functions with foreign promises.


### Event Loop Integration

In order to keep the stack size constant, Guzzle promises are resolved
asynchronously using a task queue. When waiting on promises synchronously, the
task queue will be automatically run to ensure that the blocking promise and
any forwarded promises are resolved. When using promises asynchronously in an
event loop, you will need to run the task queue on each tick of the loop. If
you do not run the task queue, then promises will not be resolved.

You can run the task queue using the `run()` method of the global task queue
instance.

```php
// Get the global task queue
$queue = GuzzleHttp\Promise\Utils::queue();
$queue->run();
```

For example, you could use Guzzle promises with React using a periodic timer:

```php
$loop = React\EventLoop\Factory::create();
$loop->addPeriodicTimer(0, [$queue, 'run']);
```

*TODO*: Perhaps adding a `futureTick()` on each tick would be faster?


## Implementation Notes

### Promise Resolution and Chaining is Handled Iteratively

By shuffling pending handlers from one owner to another, promises are
resolved iteratively, allowing for "infinite" then chaining.

```php
<?php
require 'vendor/autoload.php';

use GuzzleHttp\Promise\Promise;

$parent = new Promise();
$p = $parent;

for ($i = 0; $i < 1000; $i++) {
    $p = $p->then(function ($v) {
        // The stack size remains constant (a good thing)
        echo xdebug_get_stack_depth() . ', ';
        return $v + 1;
    });
}

$parent->resolve(0);
var_dump($p->wait()); // int(1000)

```

When a promise is fulfilled or rejected with a non-promise value, the promise
then takes ownership of the handlers of each child promise and delivers values
down the chain without using recursion.

When a promise is resolved with another promise, the original promise transfers
all of its pending handlers to the new promise. When the new promise is
eventually resolved, all of the pending handlers are delivered the forwarded
value.

### A Promise is the Deferred

Some promise libraries implement promises using a deferred object to represent
a computation and a promise object to represent the delivery of the result of
the computation. This is a nice separation of computation and delivery because
consumers of the promise cannot modify the value that will be eventually
delivered.

One side effect of being able to implement promise resolution and chaining
iteratively is that you need to be able for one promise to reach into the state
of another promise to shuffle around ownership of handlers. In order to achieve
this without making the handlers of a promise publicly mutable, a promise is
also the deferred value, allowing promises of the same parent class to reach
into and modify the private properties of promises of the same type. While this
does allow consumers of the value to modify the resolution or rejection of the
deferred, it is a small price to pay for keeping the stack size constant.

```php
$promise = new Promise();
$promise->then(function ($value) { echo $value; });
// The promise is the deferred value, so you can deliver a value to it.
$promise->resolve('foo');
// prints "foo"
```

## [1.6.1] - 2019-07-02

### Fixed

- Accept null and bool header values again


## [1.6.0] - 2019-06-30

### Added

- Allowed version `^3.0` of `ralouphie/getallheaders` dependency (#244)
- Added MIME type for WEBP image format (#246)
- Added more validation of values according to PSR-7 and RFC standards, e.g. status code range (#250, #272)

## [1.5.2] - 2018-12-04

### Fixed

- Check body size when getting the message summary


## [1.5.1] - 2018-12-04

### Fixed

- Get the summary of a body only if it is readable

- `3gp` and `mkv` mime types

### Changed

- Clarify exception message when stream is detached

### Deprecated

- Deprecated parsing folded header lines as per RFC 7230

### Fixed

- Fix `AppendStream::detach` to not close streams
- `InflateStream` preserves `isSeekable` attribute of the underlying stream
- `ServerRequest::getUriFromGlobals` to support URLs in query parameters


Several other fixes and improvements.


## [1.4.2] - 2017-03-20

### Fixed

- Reverted BC break to `Uri::resolve` and `Uri::removeDotSegments` by removing
  calls to `trigger_error` when deprecated methods are invoked.


## [1.4.1] - 2017-02-27

### Added

- Rriggering of silenced deprecation warnings.

### Fixed

- Reverted BC break by reintroducing behavior to automagically fix a URI with a
  relative path and an authority by adding a leading slash to the path. It's only
  deprecated now.


## [1.4.0] - 2017-02-21

### Added

- Added common URI utility methods based on RFC 3986 (see documentation in the readme):
  - `Uri::isDefaultPort`
  - `Uri::isAbsolute`
  - `Uri::isNetworkPathReference`
  - `Uri::isAbsolutePathReference`
  - `Uri::isRelativePathReference`
  - `Uri::isSameDocumentReference`
  - `Uri::composeComponents`
  - `UriNormalizer::normalize`
  - `UriNormalizer::isEquivalent`
  - `UriResolver::relativize`

### Changed

- Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
- Allow `parse_response` to parse a response without delimiting space and reason.
- Ensure each URI modification results in a valid URI according to PSR-7 discussions.
  Invalid modifications will throw an exception instead of returning a wrong URI or
  doing some magic.
  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
    because the path of a URI with an authority must start with a slash "/" or be empty
  - `(new Uri())->withScheme('http')` will return `'http://localhost'`

### Deprecated

- `Uri::resolve` in favor of `UriResolver::resolve`
- `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`

### Fixed

- `Stream::read` when length parameter <= 0.
- `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
- `ServerRequest::getUriFromGlobals` when `Host` header contains port.
- Compatibility of URIs with `file` scheme and empty host.


## [1.3.1] - 2016-06-25

### Fixed

- `Uri::__toString` for network path references, e.g. `//example.org`.
- Missing lowercase normalization for host.
- Handling of URI components in case they are `'0'` in a lot of places,
  e.g. as a user info password.
- `Uri::withAddedHeader` to correctly merge headers with different case.
- Trimming of header values in `Uri::withAddedHeader`. Header values may
  be surrounded by whitespace which should be ignored according to RFC 7230
  Section 3.2.4. This does not apply to header names.
- `Uri::withAddedHeader` with an array of header values.
- `Uri::resolve` when base path has no slash and handling of fragment.
- Handling of encoding in `Uri::with(out)QueryValue` so one can pass the
  key/value both in encoded as well as decoded form to those methods. This is
  consistent with withPath, withQuery etc.
- `ServerRequest::withoutAttribute` when attribute value is null.


## [1.3.0] - 2016-04-13

### Added

- Remaining interfaces needed for full PSR7 compatibility
  (ServerRequestInterface, UploadedFileInterface, etc.).
- Support for stream_for from scalars.

### Changed

- Can now extend Uri.

### Fixed
- A bug in validating request methods by making it more permissive.


## [1.2.3] - 2016-02-18

### Fixed

- Support in `GuzzleHttp\Psr7\CachingStream` for seeking forward on remote
  streams, which can sometimes return fewer bytes than requested with `fread`.
- Handling of gzipped responses with FNAME headers.


## [1.2.2] - 2016-01-22

### Added

- Support for URIs without any authority.
- Support for HTTP 451 'Unavailable For Legal Reasons.'
- Support for using '0' as a filename.
- Support for including non-standard ports in Host headers.


## [1.2.1] - 2015-11-02

### Changes

- Now supporting negative offsets when seeking to SEEK_END.


## [1.2.0] - 2015-08-15

### Changed

- Body as `"0"` is now properly added to a response.
- Now allowing forward seeking in CachingStream.
- Now properly parsing HTTP requests that contain proxy targets in
  `parse_request`.
- functions.php is now conditionally required.
- user-info is no longer dropped when resolving URIs.


## [1.1.0] - 2015-06-24

### Changed

- URIs can now be relative.
- `multipart/form-data` headers are now overridden case-insensitively.
- URI paths no longer encode the following characters because they are allowed
  in URIs: "(", ")", "*", "!", "'"
- A port is no longer added to a URI when the scheme is missing and no port is
  present.


## 1.0.0 - 2015-05-19

Initial release.

Currently unsupported:

- `Psr\Http\Message\ServerRequestInterface`
- `Psr\Http\Message\UploadedFileInterface`

# PSR-7 Message Implementation

This repository contains a full [PSR-7](https://www.php-fig.org/psr/psr-7/)
message implementation, several stream decorators, and some helpful
functionality like query string parsing.


[![Build Status](https://travis-ci.org/guzzle/psr7.svg?branch=master)](https://travis-ci.org/guzzle/psr7)


# Stream implementation

This package comes with a number of stream implementations and stream
decorators.


## AppendStream

`GuzzleHttp\Psr7\AppendStream`

Reads from multiple streams, one after the other.

```php
use GuzzleHttp\Psr7;

$a = Psr7\Utils::streamFor('abc, ');
$b = Psr7\Utils::streamFor('123.');
$composed = new Psr7\AppendStream([$a, $b]);

$composed->addStream(Psr7\Utils::streamFor(' Above all listen to me'));

echo $composed; // abc, 123. Above all listen to me.
```


## BufferStream

`GuzzleHttp\Psr7\BufferStream`

Provides a buffer stream that can be written to fill a buffer, and read
from to remove bytes from the buffer.

This stream returns a "hwm" metadata value that tells upstream consumers
what the configured high water mark of the stream is, or the maximum
preferred size of the buffer.

```php
use GuzzleHttp\Psr7;

// When more than 1024 bytes are in the buffer, it will begin returning
// false to writes. This is an indication that writers should slow down.
$buffer = new Psr7\BufferStream(1024);
```


## CachingStream

The CachingStream is used to allow seeking over previously read bytes on
non-seekable streams. This can be useful when transferring a non-seekable
entity body fails due to needing to rewind the stream (for example, resulting
from a redirect). Data that is read from the remote stream will be buffered in
a PHP temp stream so that previously read bytes are cached first in memory,
then on disk.

```php
use GuzzleHttp\Psr7;

$original = Psr7\Utils::streamFor(fopen('http://www.google.com', 'r'));
$stream = new Psr7\CachingStream($original);

$stream->read(1024);
echo $stream->tell();
// 1024

$stream->seek(0);
echo $stream->tell();
// 0
```


## DroppingStream

`GuzzleHttp\Psr7\DroppingStream`

Stream decorator that begins dropping data once the size of the underlying
stream becomes too full.

```php
use GuzzleHttp\Psr7;

// Create an empty stream
$stream = Psr7\Utils::streamFor();

// Start dropping data when the stream has more than 10 bytes
$dropping = new Psr7\DroppingStream($stream, 10);

$dropping->write('01234567890123456789');
echo $stream; // 0123456789
```


## FnStream

`GuzzleHttp\Psr7\FnStream`

Compose stream implementations based on a hash of functions.

Allows for easy testing and extension of a provided stream without needing
to create a concrete class for a simple extension point.

```php

use GuzzleHttp\Psr7;

$stream = Psr7\Utils::streamFor('hi');
$fnStream = Psr7\FnStream::decorate($stream, [
    'rewind' => function () use ($stream) {
        echo 'About to rewind - ';
        $stream->rewind();
        echo 'rewound!';
    }
]);

$fnStream->rewind();
// Outputs: About to rewind - rewound!
```


## InflateStream

`GuzzleHttp\Psr7\InflateStream`

Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.

This stream decorator skips the first 10 bytes of the given stream to remove
the gzip header, converts the provided stream to a PHP stream resource,
then appends the zlib.inflate filter. The stream is then converted back
to a Guzzle stream resource to be used as a Guzzle stream.


## LazyOpenStream

`GuzzleHttp\Psr7\LazyOpenStream`

Lazily reads or writes to a file that is opened only after an IO operation
take place on the stream.

```php
use GuzzleHttp\Psr7;

$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
// The file has not yet been opened...

echo $stream->read(10);
// The file is opened and read from only when needed.
```


## LimitStream

`GuzzleHttp\Psr7\LimitStream`

LimitStream can be used to read a subset or slice of an existing stream object.
This can be useful for breaking a large file into smaller pieces to be sent in
chunks (e.g. Amazon S3's multipart upload API).

```php
use GuzzleHttp\Psr7;

$original = Psr7\Utils::streamFor(fopen('/tmp/test.txt', 'r+'));
echo $original->getSize();
// >>> 1048576

// Limit the size of the body to 1024 bytes and start reading from byte 2048
$stream = new Psr7\LimitStream($original, 1024, 2048);
echo $stream->getSize();
// >>> 1024
echo $stream->tell();
// >>> 0
```


## MultipartStream

`GuzzleHttp\Psr7\MultipartStream`

Stream that when read returns bytes for a streaming multipart or
multipart/form-data stream.


## NoSeekStream

`GuzzleHttp\Psr7\NoSeekStream`

NoSeekStream wraps a stream and does not allow seeking.

```php
use GuzzleHttp\Psr7;

$original = Psr7\Utils::streamFor('foo');
$noSeek = new Psr7\NoSeekStream($original);

echo $noSeek->read(3);
// foo
var_export($noSeek->isSeekable());
// false
$noSeek->seek(0);
var_export($noSeek->read(3));
// NULL
```


## PumpStream

`GuzzleHttp\Psr7\PumpStream`

Provides a read only stream that pumps data from a PHP callable.

When invoking the provided callable, the PumpStream will pass the amount of
data requested to read to the callable. The callable can choose to ignore
this value and return fewer or more bytes than requested. Any extra data
returned by the provided callable is buffered internally until drained using
the read() function of the PumpStream. The provided callable MUST return
false when there is no more data to read.


## Implementing stream decorators

Creating a stream decorator is very easy thanks to the
`GuzzleHttp\Psr7\StreamDecoratorTrait`. This trait provides methods that
implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
stream. Just `use` the `StreamDecoratorTrait` and implement your custom
methods.

For example, let's say we wanted to call a specific function each time the last
byte is read from a stream. This could be implemented by overriding the
`read()` method.

```php
use Psr\Http\Message\StreamInterface;
use GuzzleHttp\Psr7\StreamDecoratorTrait;

class EofCallbackStream implements StreamInterface
{
    use StreamDecoratorTrait;

    private $callback;

    public function __construct(StreamInterface $stream, callable $cb)
    {
        $this->stream = $stream;
        $this->callback = $cb;
    }

    public function read($length)
    {
        $result = $this->stream->read($length);

        // Invoke the callback when EOF is hit.
        if ($this->eof()) {
            call_user_func($this->callback);
        }

        return $result;
    }
}
```

This decorator could be added to any existing stream and used like so:

```php
use GuzzleHttp\Psr7;

$original = Psr7\Utils::streamFor('foo');

$eofStream = new EofCallbackStream($original, function () {
    echo 'EOF!';
});

$eofStream->read(2);
$eofStream->read(1);
// echoes "EOF!"
$eofStream->seek(0);
$eofStream->read(3);
// echoes "EOF!"
```


## PHP StreamWrapper

You can use the `GuzzleHttp\Psr7\StreamWrapper` class if you need to use a
PSR-7 stream as a PHP stream resource.

Use the `GuzzleHttp\Psr7\StreamWrapper::getResource()` method to create a PHP
stream from a PSR-7 stream.

```php
use GuzzleHttp\Psr7\StreamWrapper;

$stream = GuzzleHttp\Psr7\Utils::streamFor('hello!');
$resource = StreamWrapper::getResource($stream);
echo fread($resource, 6); // outputs hello!
```


# Static API

There are various static methods available under the `GuzzleHttp\Psr7` namespace.


## `GuzzleHttp\Psr7\Message::toString`

`public static function toString(MessageInterface $message): string`

Returns the string representation of an HTTP message.

```php
$request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com');
echo GuzzleHttp\Psr7\Message::toString($request);
```


## `GuzzleHttp\Psr7\Message::bodySummary`

`public static function bodySummary(MessageInterface $message, int $truncateAt = 120): string|null`

Get a short summary of the message body.

Will return `null` if the response is not printable.


## `GuzzleHttp\Psr7\Message::rewindBody`

`public static function rewindBody(MessageInterface $message): void`

Attempts to rewind a message body and throws an exception on failure.

The body of the message will only be rewound if a call to `tell()`
returns a value other than `0`.


## `GuzzleHttp\Psr7\Message::parseMessage`

`public static function parseMessage(string $message): array`

Parses an HTTP message into an associative array.

The array contains the "start-line" key containing the start line of
the message, "headers" key containing an associative array of header
array values, and a "body" key containing the body of the message.


## `GuzzleHttp\Psr7\Message::parseRequestUri`

`public static function parseRequestUri(string $path, array $headers): string`

Constructs a URI for an HTTP request message.


## `GuzzleHttp\Psr7\Message::parseRequest`

`public static function parseRequest(string $message): Request`

Parses a request message string into a request object.


## `GuzzleHttp\Psr7\Message::parseResponse`

`public static function parseResponse(string $message): Response`

Parses a response message string into a response object.


## `GuzzleHttp\Psr7\Header::parse`

`public static function parse(string|array $header): array`

Parse an array of header values containing ";" separated data into an
array of associative arrays representing the header key value pair data
of the header. When a parameter does not contain a value, but just
contains a key, this function will inject a key with a '' string value.


## `GuzzleHttp\Psr7\Header::normalize`

`public static function normalize(string|array $header): array`

Converts an array of header values that may contain comma separated
headers into an array of headers with no comma separated values.


## `GuzzleHttp\Psr7\Query::parse`

`public static function parse(string $str, int|bool $urlEncoding = true): array`

Parse a query string into an associative array.

If multiple values are found for the same key, the value of that key
value pair will become an array. This function does not parse nested
PHP style arrays into an associative array (e.g., `foo[a]=1&foo[b]=2`
will be parsed into `['foo[a]' => '1', 'foo[b]' => '2'])`.


## `GuzzleHttp\Psr7\Query::build`

`public static function build(array $params, int|false $encoding = PHP_QUERY_RFC3986): string`

Build a query string from an array of key value pairs.

This function can use the return value of `parse()` to build a query
string. This function does not modify the provided keys when an array is
encountered (like `http_build_query()` would).


## `GuzzleHttp\Psr7\Utils::caselessRemove`

`public static function caselessRemove(iterable<string> $keys, $keys, array $data): array`

Remove the items given by the keys, case insensitively from the data.


## `GuzzleHttp\Psr7\Utils::copyToStream`

`public static function copyToStream(StreamInterface $source, StreamInterface $dest, int $maxLen = -1): void`

Copy the contents of a stream into another stream until the given number
of bytes have been read.


## `GuzzleHttp\Psr7\Utils::copyToString`

`public static function copyToString(StreamInterface $stream, int $maxLen = -1): string`

Copy the contents of a stream into a string until the given number of
bytes have been read.


## `GuzzleHttp\Psr7\Utils::hash`

`public static function hash(StreamInterface $stream, string $algo, bool $rawOutput = false): string`

Calculate a hash of a stream.

This method reads the entire stream to calculate a rolling hash, based on
PHP's `hash_init` functions.


## `GuzzleHttp\Psr7\Utils::modifyRequest`

`public static function modifyRequest(RequestInterface $request, array $changes): RequestInterface`

Clone and modify a request with the given changes.

This method is useful for reducing the number of clones needed to mutate
a message.

- method: (string) Changes the HTTP method.
- set_headers: (array) Sets the given headers.
- remove_headers: (array) Remove the given headers.
- body: (mixed) Sets the given body.
- uri: (UriInterface) Set the URI.
- query: (string) Set the query string value of the URI.
- version: (string) Set the protocol version.


## `GuzzleHttp\Psr7\Utils::readLine`

`public static function readLine(StreamInterface $stream, int $maxLength = null): string`

Read a line from the stream up to the maximum allowed buffer length.


## `GuzzleHttp\Psr7\Utils::streamFor`

`public static function streamFor(resource|string|null|int|float|bool|StreamInterface|callable|\Iterator $resource = '', array $options = []): StreamInterface`

Create a new stream based on the input type.

Options is an associative array that can contain the following keys:

- metadata: Array of custom metadata.
- size: Size of the stream.

This method accepts the following `$resource` types:

- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
- `string`: Creates a stream object that uses the given string as the contents.
- `resource`: Creates a stream object that wraps the given PHP stream resource.
- `Iterator`: If the provided value implements `Iterator`, then a read-only
  stream object will be created that wraps the given iterable. Each time the
  stream is read from, data from the iterator will fill a buffer and will be
  continuously called until the buffer is equal to the requested read size.
  Subsequent read calls will first read from the buffer and then call `next`
  on the underlying iterator until it is exhausted.
- `object` with `__toString()`: If the object has the `__toString()` method,
  the object will be cast to a string and then a stream will be returned that
  uses the string value.
- `NULL`: When `null` is passed, an empty stream object is returned.
- `callable` When a callable is passed, a read-only stream object will be
  created that invokes the given callable. The callable is invoked with the
  number of suggested bytes to read. The callable can return any number of
  bytes, but MUST return `false` when there is no more data to return. The
  stream object that wraps the callable will invoke the callable until the
  number of requested bytes are available. Any additional bytes will be
  buffered and used in subsequent reads.

```php
$stream = GuzzleHttp\Psr7\Utils::streamFor('foo');
$stream = GuzzleHttp\Psr7\Utils::streamFor(fopen('/path/to/file', 'r'));

$generator = function ($bytes) {
    for ($i = 0; $i < $bytes; $i++) {
        yield ' ';
    }
}

$stream = GuzzleHttp\Psr7\Utils::streamFor($generator(100));
```


## `GuzzleHttp\Psr7\Utils::tryFopen`

`public static function tryFopen(string $filename, string $mode): resource`

Safely opens a PHP stream resource using a filename.

When fopen fails, PHP normally raises a warning. This function adds an
error handler that checks for errors and throws an exception instead.


## `GuzzleHttp\Psr7\Utils::uriFor`

`public static function uriFor(string|UriInterface $uri): UriInterface`

Returns a UriInterface for the given value.

This function accepts a string or UriInterface and returns a
UriInterface for the given value. If the value is already a
UriInterface, it is returned as-is.


## `GuzzleHttp\Psr7\MimeType::fromFilename`

`public static function fromFilename(string $filename): string|null`

Determines the mimetype of a file by looking at its extension.


## `GuzzleHttp\Psr7\MimeType::fromExtension`

`public static function fromExtension(string $extension): string|null`

Maps a file extensions to a mimetype.


## Upgrading from Function API

The static API was first introduced in 1.7.0, in order to mitigate problems with functions conflicting between global and local copies of the package. The function API will be removed in 2.0.0. A migration table has been provided here for your convenience:

| Original Function | Replacement Method |
|----------------|----------------|
| `str` | `Message::toString` |
| `uri_for` | `Utils::uriFor` |
| `stream_for` | `Utils::streamFor` |
| `parse_header` | `Header::parse` |
| `normalize_header` | `Header::normalize` |
| `modify_request` | `Utils::modifyRequest` |
| `rewind_body` | `Message::rewindBody` |
| `try_fopen` | `Utils::tryFopen` |
| `copy_to_string` | `Utils::copyToString` |
| `copy_to_stream` | `Utils::copyToStream` |
| `hash` | `Utils::hash` |
| `readline` | `Utils::readLine` |
| `parse_request` | `Message::parseRequest` |
| `parse_response` | `Message::parseResponse` |
| `parse_query` | `Query::parse` |
| `build_query` | `Query::build` |
| `mimetype_from_filename` | `MimeType::fromFilename` |

# Additional URI Methods

Aside from the standard `Psr\Http\Message\UriInterface` implementation in form of the `GuzzleHttp\Psr7\Uri` class,
this library also provides additional functionality when working with URIs as static methods.

## URI Types

An instance of `Psr\Http\Message\UriInterface` can either be an absolute URI or a relative reference.
An absolute URI has a scheme. A relative reference is used to express a URI relative to another URI,
the base URI. Relative references can be divided into several forms according to
[RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2):

- network-path references, e.g. `//example.com/path`
- absolute-path references, e.g. `/path`
- relative-path references, e.g. `subpath`

The following methods can be used to identify the type of the URI.

### `GuzzleHttp\Psr7\Uri::isAbsolute`

`public static function isAbsolute(UriInterface $uri): bool`

Whether the URI is absolute, i.e. it has a scheme.

### `GuzzleHttp\Psr7\Uri::isNetworkPathReference`

`public static function isNetworkPathReference(UriInterface $uri): bool`

Whether the URI is a network-path reference. A relative reference that begins with two slash characters is
termed an network-path reference.

### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference`

`public static function isAbsolutePathReference(UriInterface $uri): bool`

Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is
termed an absolute-path reference.

### `GuzzleHttp\Psr7\Uri::isRelativePathReference`

`public static function isRelativePathReference(UriInterface $uri): bool`

Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is
termed a relative-path reference.

### `GuzzleHttp\Psr7\Uri::isSameDocumentReference`

`public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool`

Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its
fragment component, identical to the base URI. When no base URI is given, only an empty URI reference
(apart from its fragment) is considered a same-document reference.

## URI Components

Additional methods to work with URI components.

### `GuzzleHttp\Psr7\Uri::isDefaultPort`

`public static function isDefaultPort(UriInterface $uri): bool`

Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null
or the standard port. This method can be used independently of the implementation.

### `GuzzleHttp\Psr7\Uri::composeComponents`

`public static function composeComponents($scheme, $authority, $path, $query, $fragment): string`

Composes a URI reference string from its various components according to
[RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called
manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`.

### `GuzzleHttp\Psr7\Uri::fromParts`

`public static function fromParts(array $parts): UriInterface`

Creates a URI from a hash of [`parse_url`](https://www.php.net/manual/en/function.parse-url.php) components.


### `GuzzleHttp\Psr7\Uri::withQueryValue`

`public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface`

Creates a new URI with a specific query string value. Any existing query string values that exactly match the
provided key are removed and replaced with the given key value pair. A value of null will set the query string
key without a value, e.g. "key" instead of "key=value".

### `GuzzleHttp\Psr7\Uri::withQueryValues`

`public static function withQueryValues(UriInterface $uri, array $keyValueArray): UriInterface`

Creates a new URI with multiple query string values. It has the same behavior as `withQueryValue()` but for an
associative array of key => value.

### `GuzzleHttp\Psr7\Uri::withoutQueryValue`

`public static function withoutQueryValue(UriInterface $uri, $key): UriInterface`

Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the
provided key are removed.

## Cross-Origin Detection

`GuzzleHttp\Psr7\UriComparator` provides methods to determine if a modified URL should be considered cross-origin.

### `GuzzleHttp\Psr7\UriComparator::isCrossOrigin`

`public static function isCrossOrigin(UriInterface $original, UriInterface $modified): bool`

Determines if a modified URL should be considered cross-origin with respect to an original URL.

## Reference Resolution

`GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according
to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers
do when resolving a link in a website based on the current request URI.

### `GuzzleHttp\Psr7\UriResolver::resolve`

`public static function resolve(UriInterface $base, UriInterface $rel): UriInterface`

Converts the relative URI into a new URI that is resolved against the base URI.

### `GuzzleHttp\Psr7\UriResolver::removeDotSegments`

`public static function removeDotSegments(string $path): string`

Removes dot segments from a path and returns the new path according to
[RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4).

### `GuzzleHttp\Psr7\UriResolver::relativize`

`public static function relativize(UriInterface $base, UriInterface $target): UriInterface`

Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve():

```php
(string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target))
```

One use-case is to use the current request URI as base URI and then generate relative links in your documents
to reduce the document size or offer self-contained downloadable document archives.

```php
$base = new Uri('http://example.com/a/b/');
echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c'));  // prints 'c'.
echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y'));  // prints '../x/y'.
echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'.
echo UriResolver::relativize($base, new Uri('http://example.org/a/b/'));   // prints '//example.org/a/b/'.
```

## Normalization and Comparison

`GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to
[RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6).

### `GuzzleHttp\Psr7\UriNormalizer::normalize`

`public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface`

Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface.
This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask
of normalizations to apply. The following normalizations are available:

- `UriNormalizer::PRESERVING_NORMALIZATIONS`

    Default normalizations which only include the ones that preserve semantics.

- `UriNormalizer::CAPITALIZE_PERCENT_ENCODING`

    All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized.

    Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b`

- `UriNormalizer::DECODE_UNRESERVED_CHARACTERS`

    Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of
    ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should
    not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved
    characters by URI normalizers.

    Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/`

- `UriNormalizer::CONVERT_EMPTY_PATH`

    Converts the empty path to "/" for http and https URIs.

    Example: `http://example.org` → `http://example.org/`

- `UriNormalizer::REMOVE_DEFAULT_HOST`

    Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host
    "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to
    RFC 3986.

    Example: `file://localhost/myfile` → `file:///myfile`

- `UriNormalizer::REMOVE_DEFAULT_PORT`

    Removes the default port of the given URI scheme from the URI.

    Example: `http://example.org:80/` → `http://example.org/`

- `UriNormalizer::REMOVE_DOT_SEGMENTS`

    Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would
    change the semantics of the URI reference.

    Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html`

- `UriNormalizer::REMOVE_DUPLICATE_SLASHES`

    Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes
    and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization
    may change the semantics. Encoded slashes (%2F) are not removed.

    Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html`

- `UriNormalizer::SORT_QUERY_PARAMETERS`

    Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be
    significant (this is not defined by the standard). So this normalization is not safe and may change the semantics
    of the URI.

    Example: `?lang=en&article=fred` → `?article=fred&lang=en`

### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent`

`public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool`

Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given
`$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent.
This of course assumes they will be resolved against the same base URI. If this is not the case, determination of
equivalence or difference of relative references does not mean anything.

# KLogger: Simple Logging for PHP

A project written by [Kenny Katzgrau](http://twitter.com/katzgrau) and [Dan Horrigan](http://twitter.com/dhrrgn).

## About

KLogger is an easy-to-use [PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
compliant logging class for PHP. It isn't naive about
file permissions (which is expected). It was meant to be a class that you could
quickly include into a project and have working right away.

If you need a logger that supports PHP < 5.3, see [past releases](https://github.com/katzgrau/KLogger/releases) for KLogger versions < 1.0.0.

## Installation

### Composer

From the Command Line:

```
composer require katzgrau/klogger:dev-master
```

In your `composer.json`:

``` json
{
    "require": {
        "katzgrau/klogger": "dev-master"
    }
}
```

## Basic Usage

``` php
<?php

require 'vendor/autoload.php';

$users = [
    [
        'name' => 'Kenny Katzgrau',
        'username' => 'katzgrau',
    ],
    [
        'name' => 'Dan Horrigan',
        'username' => 'dhrrgn',
    ],
];

$logger = new Katzgrau\KLogger\Logger(__DIR__.'/logs');
$logger->info('Returned a million search results');
$logger->error('Oh dear.');
$logger->debug('Got these users from the Database.', $users);
```

### Output

```
[2014-03-20 3:35:43.762437] [INFO] Returned a million search results
[2014-03-20 3:35:43.762578] [ERROR] Oh dear.
[2014-03-20 3:35:43.762795] [DEBUG] Got these users from the Database.
    0: array(
        'name' => 'Kenny Katzgrau',
        'username' => 'katzgrau',
    )
    1: array(
        'name' => 'Dan Horrigan',
        'username' => 'dhrrgn',
    )
```

## PSR-3 Compliant

KLogger is [PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
compliant. This means it implements the `Psr\Log\LoggerInterface`.

[See Here for the interface definition.](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md#3-psrlogloggerinterface)

## Setting the Log Level Threshold

You can use the `Psr\Log\LogLevel` constants to set Log Level Threshold, so that
any messages below that level, will not be logged.

### Default Level

The default level is `DEBUG`, which means everything will be logged.

### Available Levels

``` php
<?php
use Psr\Log\LogLevel;

// These are in order of highest priority to lowest.
LogLevel::EMERGENCY;
LogLevel::ALERT;
LogLevel::CRITICAL;
LogLevel::ERROR;
LogLevel::WARNING;
LogLevel::NOTICE;
LogLevel::INFO;
LogLevel::DEBUG;
```

### Example

``` php
<?php
// The 
$logger = new Katzgrau\KLogger\Logger('/var/log/', Psr\Log\LogLevel::WARNING);
$logger->error('Uh Oh!'); // Will be logged
$logger->info('Something Happened Here'); // Will be NOT logged
```

### Additional Options

KLogger supports additional options via third parameter in the constructor:

``` php
<?php
// Example
$logger = new Katzgrau\KLogger\Logger('/var/log/', Psr\Log\LogLevel::WARNING, array (
    'extension' => 'log', // changes the log file extension
));
```

Here's the full list:

| Option | Default | Description |
| ------ | ------- | ----------- |
| dateFormat | 'Y-m-d G:i:s.u' | The format of the date in the start of the log lone (php formatted) |
| extension | 'txt' | The log file extension |
| filename | [prefix][date].[extension] | Set the filename for the log file. **This overrides the prefix and extention options.** |
| flushFrequency | `false` (disabled) | How many lines to flush the output buffer after |
| prefix  | 'log_' | The log file prefix |
| logFormat | `false` | Format of log entries |
| appendContext | `true` | When `false`, don't append context to log entries |

### Log Formatting

The `logFormat` option lets you define what each line should look like and can contain parameters representing the date, message, etc.

When a string is provided, it will be parsed for variables wrapped in braces (`{` and `}`) and replace them with the appropriate value:

| Parameter | Description |
| --------- | ----------- |
| date | Current date (uses `dateFormat` option) |
| level | The PSR log level |
| level-padding | The whitespace needed to make this log level line up visually with other log levels in the log file |
| priority | Integer value for log level (see `$logLevels`) |
| message | The message being logged |
| context | JSON-encoded context |

#### Tab-separated

Same as default format but separates parts with tabs rather than spaces:

    $logFormat = "[{date}]\t[{level}]\t{message}";

#### Custom variables and static text

Inject custom content into log messages:

    $logFormat = "[{date}] [$var] StaticText {message}";

#### JSON

To output pure JSON, set `appendContext` to `false` and provide something like the below as the value of the `logFormat` option:

```
$logFormat = json_encode([
    'datetime' => '{date}',
    'logLevel' => '{level}',
    'message'  => '{message}',
    'context'  => '{context}',
]);
```

The output will look like:

    {"datetime":"2015-04-16 10:28:41.186728","logLevel":"INFO","message":"Message content","context":"{"1":"foo","2":"bar"}"}
    
#### Pretty Formatting with Level Padding

For the obsessive compulsive

    $logFormat = "[{date}] [{level}]{level-padding} {message}";

... or ...

    $logFormat = "[{date}] [{level}{level-padding}] {message}";

## Why use KLogger?

Why not? Just drop it in and go. If it saves you time and does what you need,
go for it! Take a line from the book of our C-code fathers: "`build` upon the
work of others".

## Who uses KLogger?

Klogger has been used in projects at:

    * The University of Iowa
    * The University of Laverne
    * The New Jersey Institute of Technology
    * Middlesex Hospital in NJ

Additionally, it's been used in numerous projects, both commercial and personal.

                  GNU LESSER GENERAL PUBLIC LICENSE
                       Version 2.1, February 1999

 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

[This is the first released version of the Lesser GPL.  It also counts
 as the successor of the GNU Library Public License, version 2, hence
 the version number 2.1.]

                            Preamble

  The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.

  This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it.  You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.

  When we speak of free software, we are referring to freedom of use,
not price.  Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.

  To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights.  These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.

  For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you.  You must make sure that they, too, receive or can get the source
code.  If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it.  And you must show them these terms so they know their rights.

  We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.

  To protect each distributor, we want to make it very clear that
there is no warranty for the free library.  Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.

  Finally, software patents pose a constant threat to the existence of
any free program.  We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder.  Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.

  Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License.  This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License.  We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.

  When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library.  The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom.  The Lesser General
Public License permits more lax criteria for linking other code with
the library.

  We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License.  It also provides other free software developers Less
of an advantage over competing non-free programs.  These disadvantages
are the reason we use the ordinary General Public License for many
libraries.  However, the Lesser license provides advantages in certain
special circumstances.

  For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard.  To achieve this, non-free programs must be
allowed to use the library.  A more frequent case is that a free
library does the same job as widely used non-free libraries.  In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.

  In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software.  For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.

  Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.

  The precise terms and conditions for copying, distribution and
modification follow.  Pay close attention to the difference between a
"work based on the library" and a "work that uses the library".  The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.

                  GNU LESSER GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".

  A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.

  The "Library", below, refers to any such software library or work
which has been distributed under these terms.  A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language.  (Hereinafter, translation is
included without limitation in the term "modification".)

  "Source code" for a work means the preferred form of the work for
making modifications to it.  For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.

  Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it).  Whether that is true depends on what the Library does
and what the program that uses the Library does.

  1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.

  You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.

  2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

    a) The modified work must itself be a software library.

    b) You must cause the files modified to carry prominent notices
    stating that you changed the files and the date of any change.

    c) You must cause the whole of the work to be licensed at no
    charge to all third parties under the terms of this License.

    d) If a facility in the modified Library refers to a function or a
    table of data to be supplied by an application program that uses
    the facility, other than as an argument passed when the facility
    is invoked, then you must make a good faith effort to ensure that,
    in the event an application does not supply such function or
    table, the facility still operates, and performs whatever part of
    its purpose remains meaningful.

    (For example, a function in a library to compute square roots has
    a purpose that is entirely well-defined independent of the
    application.  Therefore, Subsection 2d requires that any
    application-supplied function or table used by this function must
    be optional: if the application does not supply it, the square
    root function must still compute square roots.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.

In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

  3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library.  To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License.  (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.)  Do not make any other change in
these notices.

  Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.

  This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.

  4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.

  If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.

  5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library".  Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.

  However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library".  The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.

  When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library.  The
threshold for this to be true is not precisely defined by law.

  If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work.  (Executables containing this object code plus portions of the
Library will still fall under Section 6.)

  Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.

  6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.

  You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License.  You must supply a copy of this License.  If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License.  Also, you must do one
of these things:

    a) Accompany the work with the complete corresponding
    machine-readable source code for the Library including whatever
    changes were used in the work (which must be distributed under
    Sections 1 and 2 above); and, if the work is an executable linked
    with the Library, with the complete machine-readable "work that
    uses the Library", as object code and/or source code, so that the
    user can modify the Library and then relink to produce a modified
    executable containing the modified Library.  (It is understood
    that the user who changes the contents of definitions files in the
    Library will not necessarily be able to recompile the application
    to use the modified definitions.)

    b) Use a suitable shared library mechanism for linking with the
    Library.  A suitable mechanism is one that (1) uses at run time a
    copy of the library already present on the user's computer system,
    rather than copying library functions into the executable, and (2)
    will operate properly with a modified version of the library, if
    the user installs one, as long as the modified version is
    interface-compatible with the version that the work was made with.

    c) Accompany the work with a written offer, valid for at
    least three years, to give the same user the materials
    specified in Subsection 6a, above, for a charge no more
    than the cost of performing this distribution.

    d) If distribution of the work is made by offering access to copy
    from a designated place, offer equivalent access to copy the above
    specified materials from the same place.

    e) Verify that the user has already received a copy of these
    materials or that you have already sent this user a copy.

  For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it.  However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.

  It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system.  Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.

  7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:

    a) Accompany the combined library with a copy of the same work
    based on the Library, uncombined with any other library
    facilities.  This must be distributed under the terms of the
    Sections above.

    b) Give prominent notice with the combined library of the fact
    that part of it is a work based on the Library, and explaining
    where to find the accompanying uncombined form of the same work.

  8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License.  Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License.  However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.

  9. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Library or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.

  10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.

  11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all.  For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.

If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

  12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded.  In such case, this License incorporates the limitation as if
written in the body of this License.

  13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number.  If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation.  If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.

  14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission.  For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this.  Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.

                            NO WARRANTY

  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.

                     END OF TERMS AND CONDITIONS

           How to Apply These Terms to Your New Libraries

  If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change.  You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).

  To apply these terms, attach the following notices to the library.  It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.

    <one line to give the library's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    This library is free software; you can redistribute it and/or
    modify it under the terms of the GNU Lesser General Public
    License as published by the Free Software Foundation; either
    version 2.1 of the License, or (at your option) any later version.

    This library is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
    Lesser General Public License for more details.

    You should have received a copy of the GNU Lesser General Public
    License along with this library; if not, write to the Free Software
    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA

Also add information on how to contact you by electronic and paper mail.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary.  Here is a sample; alter the names:

  Yoyodyne, Inc., hereby disclaims all copyright interest in the
  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

- SMTP authentication with LOGIN, PLAIN, CRAM-MD5, and XOAUTH2 mechanisms over SMTPS and SMTP+STARTTLS transports
- Validates email addresses automatically
- Protects against header injection attacks
- Error messages in over 50 languages!
- DKIM and S/MIME signing support
- Compatible with PHP 5.5 and later, including PHP 8.1
- Namespaced to prevent name clashes
- Much more!

## Why you might need it
Many PHP developers need to send email from their code. The only PHP function that supports this directly is [`mail()`](https://www.php.net/manual/en/function.mail.php). However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments.

Formatting email correctly is surprisingly difficult. There are myriad overlapping (and conflicting) standards, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the `mail()` function directly is just plain wrong, if not unsafe!

The PHP `mail()` function usually sends via a local mail server, typically fronted by a `sendmail` binary on Linux, BSD, and macOS platforms, however, Windows usually doesn't include a local mail server; PHPMailer's integrated SMTP client allows email sending on all platforms without needing a local mail server. Be aware though, that the `mail()` function should be avoided when possible; it's both faster and [safer](https://exploitbox.io/paper/Pwning-PHP-Mail-Function-For-Fun-And-RCE.html) to use SMTP to localhost.

*Please* don't be tempted to do it yourself – if you don't use PHPMailer, there are many other excellent libraries that
you should look at before rolling your own. Try [SwiftMailer](https://swiftmailer.symfony.com/)
, [Laminas/Mail](https://docs.laminas.dev/laminas-mail/), [ZetaComponents](https://github.com/zetacomponents/Mail) etc.

## License
This software is distributed under the [LGPL 2.1](http://www.gnu.org/licenses/lgpl-2.1.html) license, along with the [GPL Cooperation Commitment](https://gplcc.github.io/gplcc/). Please read [LICENSE](https://github.com/PHPMailer/PHPMailer/blob/master/LICENSE) for information on the software availability and distribution.

## Installation & loading
PHPMailer is available on [Packagist](https://packagist.org/packages/phpmailer/phpmailer) (using semantic versioning), and installation via [Composer](https://getcomposer.org) is the recommended way to install PHPMailer. Just add this line to your `composer.json` file:

```json
"phpmailer/phpmailer": "^6.5"
```

or run

```sh
composer require phpmailer/phpmailer
```

Note that the `vendor` folder and the `vendor/autoload.php` script are generated by Composer; they are not part of PHPMailer.

If you want to use the Gmail XOAUTH2 authentication class, you will also need to add a dependency on the `league/oauth2-client` package in your `composer.json`.

Alternatively, if you're not using Composer, you
can [download PHPMailer as a zip file](https://github.com/PHPMailer/PHPMailer/archive/master.zip), (note that docs and examples are not included in the zip file), then copy the contents of the PHPMailer folder into one of the `include_path` directories specified in your PHP configuration and load each class file manually:

```php
<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'path/to/PHPMailer/src/Exception.php';
require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';
```

If you're not using the `SMTP` class explicitly (you're probably not), you don't need a `use` line for the SMTP class. Even if you're not using exceptions, you do still need to load the `Exception` class as it is used internally.

## Legacy versions
PHPMailer 5.2 (which is compatible with PHP 5.0 — 7.0) is no longer supported, even for security updates. You will find the latest version of 5.2 in the [5.2-stable branch](https://github.com/PHPMailer/PHPMailer/tree/5.2-stable). If you're using PHP 5.5 or later (which you should be), switch to the 6.x releases.

### Upgrading from 5.2
The biggest changes are that source files are now in the `src/` folder, and PHPMailer now declares the namespace `PHPMailer\PHPMailer`. This has several important effects – [read the upgrade guide](https://github.com/PHPMailer/PHPMailer/tree/master/UPGRADING.md) for more details.

### Minimal installation
While installing the entire package manually or with Composer is simple, convenient, and reliable, you may want to include only vital files in your project. At the very least you will need [src/PHPMailer.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/PHPMailer.php). If you're using SMTP, you'll need [src/SMTP.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/SMTP.php), and if you're using POP-before SMTP (*very* unlikely!), you'll need [src/POP3.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/POP3.php). You can skip the [language](https://github.com/PHPMailer/PHPMailer/tree/master/language/) folder if you're not showing errors to users and can make do with English-only errors. If you're using XOAUTH2 you will need [src/OAuth.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/OAuth.php) as well as the Composer dependencies for the services you wish to authenticate with. Really, it's much easier to use Composer!

## A Simple Example

```php
<?php
//Import PHPMailer classes into the global namespace
//These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

//Load Composer's autoloader
require 'vendor/autoload.php';

//Create an instance; passing `true` enables exceptions
$mail = new PHPMailer(true);

try {
    //Server settings
    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      //Enable verbose debug output
    $mail->isSMTP();                                            //Send using SMTP
    $mail->Host       = 'smtp.example.com';                     //Set the SMTP server to send through
    $mail->SMTPAuth   = true;                                   //Enable SMTP authentication
    $mail->Username   = 'user@example.com';                     //SMTP username
    $mail->Password   = 'secret';                               //SMTP password
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS;            //Enable implicit TLS encryption
    $mail->Port       = 465;                                    //TCP port to connect to; use 587 if you have set `SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS`

    //Recipients
    $mail->setFrom('from@example.com', 'Mailer');
    $mail->addAddress('joe@example.net', 'Joe User');     //Add a recipient
    $mail->addAddress('ellen@example.com');               //Name is optional
    $mail->addReplyTo('info@example.com', 'Information');
    $mail->addCC('cc@example.com');
    $mail->addBCC('bcc@example.com');

    //Attachments
    $mail->addAttachment('/var/tmp/file.tar.gz');         //Add attachments
    $mail->addAttachment('/tmp/image.jpg', 'new.jpg');    //Optional name

    //Content
    $mail->isHTML(true);                                  //Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
```

You'll find plenty to play with in the [examples](https://github.com/PHPMailer/PHPMailer/tree/master/examples) folder, which covers many common scenarios including sending through gmail, building contact forms, sending to mailing lists, and more.

If you are re-using the instance (e.g. when sending to a mailing list), you may need to clear the recipient list to avoid sending duplicate messages. See [the mailing list example](https://github.com/PHPMailer/PHPMailer/blob/master/examples/mailing_list.phps) for further guidance.

That's it. You should now be ready to use PHPMailer!

PHPMailer defaults to English, but in the [language](https://github.com/PHPMailer/PHPMailer/tree/master/language/) folder you'll find many translations for PHPMailer error messages that you may encounter. Their filenames contain [ISO 639-1](http://en.wikipedia.org/wiki/ISO_639-1) language code for the translations, for example `fr` for French. To specify a language, you need to tell PHPMailer which one to use, like this:

```php
//To load the French version
$mail->setLanguage('fr', '/optional/path/to/language/directory/');
```

We welcome corrections and new languages – if you're looking for corrections, run the [PHPMailerLangTest.php](https://github.com/PHPMailer/PHPMailer/tree/master/test/PHPMailerLangTest.php) script in the tests folder and it will show any missing translations.

## Documentation
Start reading at the [GitHub wiki](https://github.com/PHPMailer/PHPMailer/wiki). If you're having trouble, head for [the troubleshooting guide](https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting) as it's frequently updated.

Examples of how to use PHPMailer for common scenarios can be found in the [examples](https://github.com/PHPMailer/PHPMailer/tree/master/examples) folder. If you're looking for a good starting point, we recommend you start with [the Gmail example](https://github.com/PHPMailer/PHPMailer/tree/master/examples/gmail.phps).

To reduce PHPMailer's deployed code footprint, examples are not included if you load PHPMailer via Composer or via [GitHub's zip file download](https://github.com/PHPMailer/PHPMailer/archive/master.zip), so you'll need to either clone the git repository or use the above links to get to the examples directly.

Complete generated API documentation is [available online](https://phpmailer.github.io/PHPMailer/).

You can generate complete API-level documentation by running `phpdoc` in the top-level folder, and documentation will appear in the `docs` folder, though you'll need to have [PHPDocumentor](http://www.phpdoc.org) installed. You may find [the unit tests](https://github.com/PHPMailer/PHPMailer/blob/master/test/PHPMailerTest.php) a good reference for how to do various operations such as encryption.

If the documentation doesn't cover what you need, search the [many questions on Stack Overflow](http://stackoverflow.com/questions/tagged/phpmailer), and before you ask a question about "SMTP Error: Could not connect to SMTP host.", [read the troubleshooting guide](https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting).

## Tests
[PHPMailer tests](https://github.com/PHPMailer/PHPMailer/tree/master/test/) use PHPUnit 9, with [a polyfill](https://github.com/Yoast/PHPUnit-Polyfills) to let 9-style tests run on older PHPUnit and PHP versions.

[![Test status](https://github.com/PHPMailer/PHPMailer/workflows/Tests/badge.svg)](https://github.com/PHPMailer/PHPMailer/actions)

If this isn't passing, is there something you can do to help?

## Security
Please disclose any vulnerabilities found responsibly – report security issues to the maintainers privately.

See [SECURITY](https://github.com/PHPMailer/PHPMailer/tree/master/SECURITY.md) and [PHPMailer's security advisories on GitHub](https://github.com/PHPMailer/PHPMailer/security). 

## Contributing
Please submit bug reports, suggestions and pull requests to the [GitHub issue tracker](https://github.com/PHPMailer/PHPMailer/issues).

We're particularly interested in fixing edge-cases, expanding test coverage and updating translations.

# Security notices relating to PHPMailer

Please disclose any security issues or vulnerabilities found through [Tidelift's coordinated disclosure system](https://tidelift.com/security) or to the maintainers privately.

PHPMailer 6.4.1 and earlier contain a vulnerability that can result in untrusted code being called (if such code is injected into the host project's scope by other means). If the `$patternselect` parameter to `validateAddress()` is set to `'php'` (the default, defined by `PHPMailer::$validator`), and the global namespace contains a function called `php`, it will be called in preference to the built-in validator of the same name. Mitigated in PHPMailer 6.5.0 by denying the use of simple strings as validator function names. Recorded as [CVE-2021-3603](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-3603). Reported by [Vikrant Singh Chauhan](mailto:vi@hackberry.xyz) via [huntr.dev](https://www.huntr.dev/).

PHPMailer versions 6.4.1 and earlier contain a possible remote code execution vulnerability through the `$lang_path` parameter of the `setLanguage()` method. If the `$lang_path` parameter is passed unfiltered from user input, it can be set to [a UNC path](https://docs.microsoft.com/en-us/dotnet/standard/io/file-path-formats#unc-paths), and if an attacker is also able to persuade the server to load a file from that UNC path, a script file under their control may be executed. This vulnerability only applies to systems that resolve UNC paths, typically only Microsoft Windows.
PHPMailer 6.5.0 mitigates this by no longer treating translation files as PHP code, but by parsing their text content directly. This approach avoids the possibility of executing unknown code while retaining backward compatibility. This isn't ideal, so the current translation format is deprecated and will be replaced in the next major release. Recorded as [CVE-2021-34551](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-34551). Reported by [Jilin Diting Information Technology Co., Ltd](https://listensec.com) via Tidelift.

PHPMailer versions between 6.1.8 and 6.4.0 contain a regression of the earlier CVE-2018-19296 object injection vulnerability as a result of [a fix for Windows UNC paths in 6.1.8](https://github.com/PHPMailer/PHPMailer/commit/e2e07a355ee8ff36aba21d0242c5950c56e4c6f9). Recorded as [CVE-2020-36326](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-36326). Reported by Fariskhi Vidyan via Tidelift. 6.4.1 fixes this issue, and also enforces stricter checks for URL schemes in local path contexts.

PHPMailer versions 6.1.5 and earlier contain an output escaping bug that occurs in `Content-Type` and `Content-Disposition` when filenames passed into `addAttachment` and other methods that accept attachment names contain double quote characters, in contravention of RFC822 3.4.1. No specific vulnerability has been found relating to this, but it could allow file attachments to bypass attachment filters that are based on matching filename extensions. Recorded as [CVE-2020-13625](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-13625). Reported by Elar Lang of Clarified Security.

PHPMailer versions prior to 6.0.6 and 5.2.27 are vulnerable to an object injection attack by passing `phar://` paths into `addAttachment()` and other functions that may receive unfiltered local paths, possibly leading to RCE. Recorded as [CVE-2018-19296](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2018-19296). See [this article](https://knasmueller.net/5-answers-about-php-phar-exploitation) for more info on this type of vulnerability. Mitigated by blocking the use of paths containing URL-protocol style prefixes such as `phar://`. Reported by Sehun Oh of cyberone.kr.

PHPMailer versions prior to 5.2.24 (released July 26th 2017) have an XSS vulnerability in one of the code examples, [CVE-2017-11503](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-11503). The `code_generator.phps` example did not filter user input prior to output. This file is distributed with a `.phps` extension, so it it not normally executable unless it is explicitly renamed, and the file is not included when PHPMailer is loaded through composer, so it is safe by default. There was also an undisclosed potential XSS vulnerability in the default exception handler (unused by default). Patches for both issues kindly provided by Patrick Monnerat of the Fedora Project.

PHPMailer versions prior to 5.2.22 (released January 9th 2017) have a local file disclosure vulnerability, [CVE-2017-5223](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-5223). If content passed into `msgHTML()` is sourced from unfiltered user input, relative paths can map to absolute local file paths and added as attachments. Also note that `addAttachment` (just like `file_get_contents`, `passthru`, `unlink`, etc) should not be passed user-sourced params either! Reported by Yongxiang Li of Asiasecurity.

PHPMailer versions prior to 5.2.20 (released December 28th 2016) are vulnerable to [CVE-2016-10045](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-10045) a remote code execution vulnerability, responsibly reported by [Dawid Golunski](https://legalhackers.com/advisories/PHPMailer-Exploit-Remote-Code-Exec-CVE-2016-10045-Vuln-Patch-Bypass.html), and patched by Paul Buonopane (@Zenexer).

PHPMailer versions prior to 5.2.18 (released December 2016) are vulnerable to [CVE-2016-10033](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-10033) a remote code execution vulnerability, responsibly reported by [Dawid Golunski](http://legalhackers.com/advisories/PHPMailer-Exploit-Remote-Code-Exec-CVE-2016-10033-Vuln.html).

PHPMailer versions prior to 5.2.14 (released November 2015) are vulnerable to [CVE-2015-8476](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-8476) an SMTP CRLF injection bug permitting arbitrary message sending.

PHPMailer versions prior to 5.2.10 (released May 2015) are vulnerable to [CVE-2008-5619](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2008-5619), a remote code execution vulnerability in the bundled html2text library. This file was removed in 5.2.10, so if you are using a version prior to that and make use of the html2text function, it's vitally important that you upgrade and remove this file.

PHPMailer versions prior to 2.0.7 and 2.2.1 are vulnerable to [CVE-2012-0796](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-0796), an email header injection attack.

Joomla 1.6.0 uses PHPMailer in an unsafe way, allowing it to reveal local file paths, reported in [CVE-2011-3747](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2011-3747).

PHPMailer didn't sanitise the `$lang_path` parameter in `SetLanguage`. This wasn't a problem in itself, but some apps (PHPClassifieds, ATutor) also failed to sanitise user-provided parameters passed to it, permitting semi-arbitrary local file inclusion, reported in [CVE-2010-4914](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2010-4914), [CVE-2007-2021](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2007-2021) and [CVE-2006-5734](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2006-5734).

PHPMailer 1.7.2 and earlier contained a possible DDoS vulnerability reported in [CVE-2005-1807](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2005-1807).

PHPMailer 1.7 and earlier (June 2003) have a possible vulnerability in the `SendmailSend` method where shell commands may not be sanitised. Reported in [CVE-2007-3215](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2007-3215).

/**
 * PHPMailer POP-Before-SMTP Authentication Class.
 * Specifically for PHPMailer to use for RFC1939 POP-before-SMTP authentication.
 * 1) This class does not support APOP authentication.
 * 2) Opening and closing lots of POP3 connections can be quite slow. If you need
 *   to send a batch of emails then just perform the authentication once at the start,
 *   and then loop through your mail sending script. Providing this process doesn't
 *   take longer than the verification period lasts on your POP3 server, you should be fine.
 * 3) This is really ancient technology; you should only need to use it to talk to very old systems.
 * 4) This POP3 class is deliberately lightweight and incomplete, implementing just
 *   enough to do authentication.
 *   If you want a more complete class there are other POP3 classes for PHP available.

6.6.4# Changelog

All notable changes to this project will be documented in this file, in reverse chronological order by release.

## 1.0.1 - 2016-08-06

### Added

- Nothing.

### Deprecated

- Nothing.

### Removed

- Nothing.

### Fixed

- Updated all `@return self` annotation references in interfaces to use
  `@return static`, which more closelly follows the semantics of the
  specification.
- Updated the `MessageInterface::getHeaders()` return annotation to use the
  value `string[][]`, indicating the format is a nested array of strings.
- Updated the `@link` annotation for `RequestInterface::withRequestTarget()`
  to point to the correct section of RFC 7230.
- Updated the `ServerRequestInterface::withUploadedFiles()` parameter annotation
  to add the parameter name (`$uploadedFiles`).
- Updated a `@throws` annotation for the `UploadedFileInterface::moveTo()`
  method to correctly reference the method parameter (it was referencing an
  incorrect parameter name previously).

## 1.0.0 - 2016-05-18

Initial stable release; reflects accepted PSR-7 specification.

PSR Http Message
================

This repository holds all interfaces/classes/traits related to
[PSR-7](http://www.php-fig.org/psr/psr-7/).

Note that this is not a HTTP message implementation of its own. It is merely an
interface that describes a HTTP message. See the specification for more details.

PSR Log
=======

This repository holds all interfaces/classes/traits related to
[PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md).

Note that this is not a logger of its own. It is merely an interface that
describes a logger. See the specification for more details.

Installation
------------

```bash
composer require psr/log
```

Usage
-----

If you need a logger, you can use the interface like this:

```php
<?php

use Psr\Log\LoggerInterface;

class Foo
{
    private $logger;

    public function __construct(LoggerInterface $logger = null)
    {
        $this->logger = $logger;
    }

    public function doSomething()
    {
        if ($this->logger) {
            $this->logger->info('Doing work');
        }
           
        try {
            $this->doSomethingElse();
        } catch (Exception $exception) {
            $this->logger->error('Oh no!', array('exception' => $exception));
        }

        // do something useful
    }
}
```

You can then pick one of the implementations of the interface to get a logger.

If you want to implement the interface, you can require this package and
implement `Psr\Log\LoggerInterface` in your code. Please read the
[specification text](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
for details.

# Rotate

Simple file rotation utility which rotates and removes old files or folders, useful where you cannot use logrotate (e.g. a Windows system) 
or you want to rotate or delete files based on a timestamp or date contained in the filename. 

## Installation

```sh
composer require studio24/rotate
```

## Usage

You can use Rotate in two modes: rotate (renames files and removes oldest files) or delete (deletes files according to a pattern).

Import at the top of your PHP script via:

```sh
use studio24\Rotate\Rotate;
```

### Setting the filename format to match

Both Rotate and Delete pass in the filename pattern you want to match for in the constructor or via the `setFilenameFormat()` method.
This can be used to match a single file, files matching a pattern, or files with a datetime within the filename pattern. 

Rotate only works on files. Delete can also delete folders and recursively deletes any child files in that folder. 

#### Matches on leaf elements

Please note files are matched on the last leaf element. All files in the parent folder are scanned, files (and folders 
for Delete) are checked to see whether they match the specified pattern.

For example passing `path/to/*.log` will search for all files ending .log in the folder `path/to`.

#### Filename patterns

The following patterns are supported when matching files or folders:

* `debug.log` - exact match for a file called debug.log
* `*` - matches any string, for example `*.log` matches all files ending .log
* `{Ymd}` - matches time segment in a file, for example `order.{Ymd}.log` matches a file in the format order.20160401.log

#### Datetime formats

For datetime formats, any date format supported by [DateTime::createFromFormat](http://php.net/datetime.createfromformat) is allowed 
excluding the Timezone identifier `e` and whitespace and separator characters. 

### Deleting folders recursively

You can also delete folders and all child files that match. This is, however, dangerous so by default no folders can be deleted. You 
 need to explicitly add folder paths that are safe to delete via `Delete::addSafeRecursiveDeletePath($path)`. When using 
 this function you need to use the full absolute path. Use `realpath()` to expand full paths if you need to.

For example, if you want to delete all folders in `/var/www/test/staging/data/logs/` that are 1+ months old:

```
$rotate = new Delete('/var/www/test/staging/data/logs/old-logs/*');
$rotate->addSafeRecursiveDeletePath('/var/www/test/staging/data/logs/');
$files = $rotate->deleteByFilenameTime('1 month');
```

The above code would allow you to delete folders within `/var/www/test/staging/data/logs/` only. 

### Rotate

Rotate log files in a similar manner to logrotate.

The following example rotates the file debug.log, this renames debug.log to debug.log.1, debug.log.1 to debug.log.2, debug.log.2 to 
debug.log.3 and so on. It keeps 10 copies, so it deletes debug.log.10 and renames debug.log.9 to debug.log.10.

```sh
use studio24\Rotate\Rotate;

$rotate = new Rotate('path/to/debug.log');
$rotate->run();
```

#### How many copies to keep

Rotate keeps 10 copies of files by default, you can change this via:

```
$rotate->keep(20);
```

#### Rotated based on filesize
You can only rotate files when they reach a certain filesize, rather than automatically rotate each time the `$rotate->run()` method is run.
 
```
$rotate->size("12MB");
```

### Delete

Deletes files based on modification time, datetime in the filename, or based on a custom callback function.

#### Time-based

Deletes files based on the modification time. For example, to delete all JPG files in a folder over 3 months old: 

```sh
use studio24\Rotate\Delete;

$rotate = new Delete('path/to/images/*.jpg');
$deletedFiles = $rotate->deleteByFileModifiedDate('3 months');
```

The `deleteByFileModifiedDate()` method accepts either a valid DateInterval object or a relative date format as specified on 
[Relative Formats](http://php.net/manual/en/datetime.formats.relative.php).

#### Time format in filename
Deletes files based on the datetime in the filename. For example, to delete all  order logfiles with a date in their 
filename over 3 months old:

```sh
use studio24\Rotate\Delete;

$rotate = new Delete('path/to/logs/orders.YYYYMMDD.log');
$deletedFiles = $rotate->deleteByFilenameTime('3 months');
```

#### Based on a custom callback 
Deletes files based on a custom callback function, this is useful if you need to perform more complex code to assess whether a file
should be deleted. For example, to delete all image files called 1000.jpg and below:

```sh
use studio24\Rotate\Delete;
use studio24\Rotate\DirectoryIterator;

$rotate = new Delete('path/to/logs/*.jpg');
$deletedFiles = $rotate->deleteByCallback(function(DirectoryIterator $file){
    if ($file->getBasename() <= 1000) {
        return true;
    } 
    return false;
});
```

##### DirectoryIterator
The callback function must accept one parameter `$file`, which is of type `\studio24\Rotate\DirectoryIterator`.

This iterator has the following methods in addition to the normal [SPL DirectoryIterator](http://php.net/DirectoryIterator).

* `isMatch()` - whether the current file matches the filename patter we are looking for
* `hasDate()` - whether the current file has a datetime within the filename
* `getFilenameDate()` - return the datetime from the current file (as a DateTime object)

Symfony Polyfill / Php72
========================

This component provides functions added to PHP 7.2 core:

- [`spl_object_id`](https://php.net/spl_object_id)
- [`stream_isatty`](https://php.net/stream_isatty)

And also functions added to PHP 7.2 mbstring:

- [`mb_ord`](https://php.net/mb_ord)
- [`mb_chr`](https://php.net/mb_chr)
- [`mb_scrub`](https://php.net/mb_scrub)

On Windows only:

- [`sapi_windows_vt100_support`](https://php.net/sapi_windows_vt100_support)

Moved to core since 7.2 (was in the optional XML extension earlier):

- [`utf8_encode`](https://php.net/utf8_encode)
- [`utf8_decode`](https://php.net/utf8_decode)

Also, it provides constants added to PHP 7.2:

- [`PHP_FLOAT_*`](https://php.net/reserved.constants#constant.php-float-dig)
- [`PHP_OS_FAMILY`](https://php.net/reserved.constants#constant.php-os-family)
