The Base Controller Class
For convenience, Symfony2 comes with a base Controller class that assists with some of the
most common controller tasks and gives your controller class access to any resource it might
need. By extending this Controller class, you can take advantage of several helper methods.
Add the use statement atop the Controller class and then modify the HelloController to
extend it:
// src/Acme/HelloBundle/Controller/HelloController.php
namespace Acme\HelloBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
class HelloController extends Controller
{
public function indexAction($name)
{
return new Response('Hello '.$name.'!');
}
}
This doesn't actually change anything about how your controller works. In the next section,
you'll learn about the helper methods that the base controller class makes available. These
methods are just shortcuts to using core Symfony2 functionality that's available to you with or
without the use of the base Controller class. A great way to see the core functionality in
action is to look in theController class itself.
Extending the base class is optional in Symfony; it contains useful shortcuts but nothing
mandatory. You can also
extendSymfony\Component\DependencyInjection\ContainerAware. The service
container object will then be accessible via the container property.
You can also define your Controllers as Services.
Common Controller Tasks
Though a controller can do virtually anything, most controllers will perform the same basic tasks
over and over again. These tasks, such as redirecting, forwarding, rendering templates and
accessing core services, are very easy to manage in Symfony2.
