Request
A request is an object that encapsulates an incoming HTTP message: method, URL, headers, query parameters, body, and uploaded files.
PHP frameworks provide a dedicated Request object that replaces direct access to superglobals such as $_GET, $_POST, $_SERVER, and $_FILES. This makes code more testable and explicit.
PSR-7 defines a standard ServerRequestInterface that many frameworks and libraries implement, enabling interoperability.
<?php
// PSR-7 style
use Psr\Http\Message\ServerRequestInterface;
function handle(ServerRequestInterface $request): void {
$method = $request->getMethod(); // 'POST'
$query = $request->getQueryParams(); // $_GET equivalent
$body = $request->getParsedBody(); // $_POST equivalent
$header = $request->getHeaderLine('Accept');
}
// Laravel / Symfony style
use Illuminate\Http\Request;
class UserController {
public function store(Request $request): Response {
$name = $request->input('name');
$email = $request->input('email');
}
}
?>
