The Symfony PSR HTTP Message Bridge, or symfony/psr-http-message-bridge, acts as an intermediary aiding in the integration of PSR-7. It provides efficient compatibility between Symfony HTTP Messages and PSR-7 standard. This is particularly valuable when switching between or operating concurrently with Symfony and other PSR-7 compliant systems.
To use symfony/psr-http-message-bridge, you need to perform an installation via composer package manager. It's as simple as navigating to your project directory and running composer require symfony/psr-http-message-bridge in your terminal. After which, you can then use the library in your PHP code. Here's a simple usage example:
<?php
use Symfony\Bridge\PsrHttpMessage\Factory\DiactorosFactory;
use Symfony\Bridge\PsrHttpMessage\Factory\HttpFoundationFactory;
// To convert Symfony Request to PSR-7
$psr7Factory = new DiactorosFactory();
$psr7Request = $psr7Factory->createRequest($symfonyRequest);
// To convert PSR-7 response to Symfony
$httpFoundationFactory = new HttpFoundationFactory();
$symfonyResponse = $httpFoundationFactory->createResponse($psr7Response);
In the example above, we first create a PSR-7 request from a Symfony request. We later convert a PSR-7 response to a Symfony response.
For comprehensive information regarding how to use the Symfony PSR HTTP Message Bridge, you will find the official documentation on the Symfony website, specifically at this URL: https://symfony.com/doc/current/components/psr7.html. This resource offers complete and detailed instructions, serving as a useful guide for leveraging this robust Symfony package.
