PHP-HTTP: standardized HTTP for PHP

PHP-HTTP is the next step in standardizing HTTP interaction for PHP packages. It builds on top of PSR-7_, which defines interfaces for HTTP requests and responses. PSR-7 does not describe, however, the way you should create requests or send them. PHP-HTTP aims to fill that gap by offering an HTTP client interface: HTTPlug.

PHP-HTTP has three goals:

Encourage package developers to depend on the simple HTTPlug interface instead of concrete HTTP clients.
Provide good quality HTTP-related packages to the PHP community.
Over time, make HTTPlug a PHP Standards Recommendation (PSR) so that clients will directly implement the HTTPlug interface and our adapters are no longer needed.

HTTPlug

HTTPlug abstracts from HTTP clients written in PHP, offering a simple interface. It also provides an implementation-independent plugin system to build pipelines regardless of the HTTP client implementation used.

Packages

PHP-HTTP offers several packages:

Type	Description	Namespace
Clients	HTTP clients: Socket, cURL and others	`Http\Client\[Name]`
Client adapters	Adapters for other clients: Guzzle, React and others	`Http\Adapter\[Name]`
Plugins	Implementation-independent authentication, cookies and more	`Http\Client\Common\Plugin\[Name]`

Read more about :doc:`clients and adapters <clients>` and :doc:`plugins <plugins/index>`.

The future

HTTPlug, as a working example of an HTTP client interface, can serve as a basis for discussion around a future HTTP client PSR.
