nyholm/psr7

A fast PHP7 implementation of PSR-7

PSR-7 implementation

, _(*1)

A super lightweight PSR-7 implementation. Very strict and very fast., _(*2)

* Percent of completed tests in https://github.com/php-http/psr7-integration-tests, _(*3)

** Benchmark with 50.000 runs. See https://github.com/devanych/psr-http-benchmark (higher is better), _(*4)

Installation

composer require nyholm/psr7

If you are using Symfony Flex then you get all message factories registered as services., _(*5)

Usage

The PSR-7 objects do not contain any other public methods than those defined in the PSR-7 specification., _(*6)

Create objects

Use the PSR-17 factory to create requests, streams, URIs etc., _(*7)

$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();
$request = $psr17Factory->createRequest('GET', 'http://tnyholm.se');
$stream = $psr17Factory->createStream('foobar');

Sending a request

With HTTPlug or any other PSR-18 (HTTP client) you may send requests like:, _(*8)

composer require kriswallsmith/buzz

$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();
$psr18Client = new \Buzz\Client\Curl($psr17Factory);

$request = $psr17Factory->createRequest('GET', 'http://tnyholm.se');
$response = $psr18Client->sendRequest($request);

Create server requests

The nyholm/psr7-server package can be used to create server requests from PHP superglobals., _(*9)

composer require nyholm/psr7-server

$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();

$creator = new \Nyholm\Psr7Server\ServerRequestCreator(
    $psr17Factory, // ServerRequestFactory
    $psr17Factory, // UriFactory
    $psr17Factory, // UploadedFileFactory
    $psr17Factory  // StreamFactory
);

$serverRequest = $creator->fromGlobals();

Emitting a response

composer require laminas/laminas-httphandlerrunner

$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();

$responseBody = $psr17Factory->createStream('Hello world');
$response = $psr17Factory->createResponse(200)->withBody($responseBody);
(new \Laminas\HttpHandlerRunner\Emitter\SapiEmitter())->emit($response);

Our goal

This package is currently maintained by Tobias Nyholm and Martijn van der Ven. They have decided that the goal of this library should be to provide a super strict implementation of PSR-7 that is blazing fast., _(*10)

The package will never include any extra features nor helper methods. All our classes and functions exist because they are required to fulfill the PSR-7 specification., _(*11)
