 Switching the Profiler Storage
 ==============================

+In Symfony versions prior to 3.0, profiles could be stored in files, databases,
 services like Redis and Memcache, etc. Starting from Symfony 3.0, the only storage
 mechanism with built-in support is the filesystem.
 
 By default the profile stores the collected data in the ``%kernel.cache_dir%/profiler/``
 directory. If you want to use another location to store the profiles, define the
 ``dsn`` option of the ``framework.profiler``:
 
-.. code-block:: yaml
+.. configuration-block::
 
-    # app/config/config.yml
-    framework:
-        profiler:
-            dsn: 'file:/tmp/symfony/profiler'
+    .. code-block:: yaml
+
+        # app/config/config.yml
+        framework:
+            profiler:
+                dsn: 'file:/tmp/symfony/profiler'

+        </container>
+
+    .. code-block:: php
+
+        // app/config/config.php
+
+        // ...
+        $container->loadFromExtension('framework', array(
+            'profiler' => array(
+                'dsn'      => 'file:/tmp/symfony/profiler',

 You can also create your own profile storage service implementing the
 :class:``Symfony\Component\HttpKernel\Profiler\ProfilerStorageInterface`` and
