Like with all services, you can also use regular:ref:`constructor injection<services-constructor-injection>`

in your controllers.

..caution::

You can *only* pass *services* to your controller arguments in this way. It's not

possible, for example, to pass a config parameter as a controller argument,

even by using ``bind``. If you need a parameter, use the ``$this->getParameter('kernel.debug')``

shortcut or pass the value through your controller's ``__construct()`` method

and specify its value with ``bind``.

For more information about services, see the:doc:`/service_container` article.
