An Object-Oriented abstraction on top of PHP Request

use SymfonyComponentHttpFoundationRequest; $request = new Request(); // get a $_GET parameter $request->query->get('page'); // get a $_POST parameter $request->request->get('page'); // get a $_COOKIE parameter $request->cookies->get('name'); $request->getPreferredLanguage(array('en', 'fr')); $request->isXmlHttpRequest();

// get a $_FILE parameter $f = $request->files->get('image'); // $f is an instance of // SymfonyComponentHttpFoundationFileUploadedFile // guess extension, based on the mime type $n = '/path/to/file'.$file->getDefaultExtension(); $f->move($n);

new Request(); new Request( $_GET, $_POST, array(), $_COOKIE, $_FILES, $_SERVER ); Request::create('/hello/Fabien', 'GET');

An Object-Oriented abstraction on top of PHP Session

$session = $request->getSession(); $session->set('foo', 'bar'); $session->get('foo'); $session->setFlash('notice', 'Congratulations!');

An Object-Oriented abstraction on top of PHP Response

use SymfonyComponentHttpFoundationResponse; $response = new Response('Hello World', 200, array('Content-Type' => 'text/plain')); $response->send(); $response->setHeader('Content-Type', 'text/ plain'); $response->setCookie('foo', 'bar'); $response->setContent('Hello World'); $response->setStatusCode(200);
