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'); } Resources --------- Unit tests: https://github.com/symfony/symfony/tree/master/tests/Symfony/Tests/Component/HttpFoundation
