Just curious what the difference between 'extends Controller' and 'extends \Twig_extension' what does the '\' mean in this case? Is Twig_extension a class or a function inside a class. Thanks in advance

Hey Neal,

No, it just specifying a full namespace of Twig_Extension class - it actually means that Twig_Extension doesn't have a namespace at all and you can ensure in it when open this Twig/Extension.php file. If you miss this \ slash - it will mean that you use Twig_Extension class with your current namespace, i.e. Yoda\EventBundle\Twig. Let's look at both examples, which are the same:


// without `use` statement:
namespace Yoda\EventBundle\Twig;

class EventExtension extends \Twig_Extension
{
}

// or with `use` statement::
namespace Yoda\EventBundle\Twig;

use Twig_Extension;

class EventExtension extends Twig_Extension
{
}

But for classes which doesn't have namespace like DateTime, <a href="http://php.net/manual/en/book.spl.php">SPL classes</a>, etc. it's a good practice to specify root slash directly before class name instead of use the use statement.

Cheers!
