29. # web/app.php use Symfony\Component\HttpFoundation\Request; $kernel = new AppKernel('prod', false); $kernel->loadClassCache(); $request = Request::createFromGlobals(); $response = $kernel->handle($request); $response->send(); $kernel->terminate($request, $response);
30. 30 Separation of Concerns Implementation Controller View Model Modifies the model Returns model data Renders the view The Controller analyses the user request, calls the Model and passes data to the View. The View layer formats data in a dedicated format (html, json…) The Model stores the business logic and classes that manipulate data. R Router Response Request /hello/fabien
