HttpFoundation Component

HttpFoundation defines an object-oriented layer for the HTTP specification.

It provides an abstraction for requests, responses, uploaded files, cookies, sessions, ...

In this example, we get a Request object from the current PHP global variables:

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

$request = Request::createFromGlobals();
echo $request->getPathInfo();

You can also create a Request directly -- that's interesting for unit testing:

$request = Request::create('/?foo=bar', 'GET');
echo $request->getPathInfo();

And here is how to create and send a Response:

$response = new Response('Not Found', 404, array('Content-Type' => 'text/plain'));
$response->send();

The Request and the Response classes have many other methods that implement the HTTP specification.

Loading

If you are using PHP 5.3.x you must add the following to your autoloader:

// SessionHandlerInterface
if (!interface_exists('SessionHandlerInterface')) {
    $loader->registerPrefixFallback(__DIR__.'/../vendor/symfony/src/Symfony/Component/HttpFoundation/Resources/stubs');
}
