.. versionadded:: 2.0.9
This feature is available as of Twig ``1.5.x``, which was first shipped

When using PHP, you can use ``var_dump()`` if you need to quickly find the
9043 value of a variable passed. This is useful, for example, inside your controller.
The same can be achieved when using Twig by using the debug extension. This
needs to be enabled in the config:

.. configuration-block::

.. code-block:: yaml

# app/config/config.yml
services:
acme_hello.twig.extension.debug:
class: Twig_Extension_Debug
tags:

.. code-block:: xml

<!-- app/config/config.xml -->
<services>
<service id="acme_hello.twig.extension.debug" class="Twig_Extension_Debug">
<tag name="twig.extension" />
</service>
</services>

.. code-block:: php

// app/config/config.php
use Symfony\Component\DependencyInjection\Definition;

$definition->addTag('twig.extension');
$container->setDefinition('acme_hello.twig.extension.debug', $definition);

Template parameters can then be dumped using the ``dump`` function:
