guzzlehttp/psr7 is a PSR-7 HTTP message implementation for PHP. It provides request, response, URI, uploaded file, and stream objects that work with Guzzle and any other library using the PSR-7 interfaces.

Use this package directly when you need to create or inspect PSR-7 messages without sending HTTP requests. If you only want to make HTTP requests, install guzzlehttp/guzzle instead; it already depends on this package.

composer require guzzlehttp/psr7

use GuzzleHttp\Psr7\Request;
use GuzzleHttp\Psr7\Response;
use GuzzleHttp\Psr7\Utils;

$request = new Request('GET', 'https://example.com/api');
$response = new Response(200, ['Content-Type' => 'text/plain'], 'OK');
$stream = Utils::streamFor('request or response body');

echo $request->getMethod();
echo $response->getStatusCode();
echo $stream;

PSR-7 messages and URIs are immutable. Methods such as withHeader() and withUri() return a changed copy instead of modifying the original object. Streams are mutable body handles; reading, writing, seeking, and closing a stream can change its cursor, contents, or usability.

$request = $request->withHeader('Accept', 'application/json');
