-Array Cache Adapter
-===================
-
-Generally, this adapter is useful for testing purposes, as its contents are stored in memory
-and not persisted outside the running PHP process in any way. It can also be useful while
-warming up caches, due to the :method:`Symfony\\Component\\Cache\\Adapter\\ArrayAdapter::getValues`
-method.
-
-This adapter can be passed a default cache lifetime as its first parameter, and a boolean that
-toggles serialization as its second parameter::
-
-    use Symfony\Component\Cache\Adapter\ArrayAdapter;
-
-    $cache = new ArrayAdapter(
-
-        // the default lifetime (in seconds) for cache items that do not define their
-        // own lifetime, with a value 0 causing items to be stored indefinitely (i.e.
-        // until the current PHP process finishes)
-        $defaultLifetime = 0,
-
-        // if ``true``, the values saved in the cache are serialized before storing them
-        $storeSerialized = true
-    );
