+Objects for Mappings
+....................
+
+Yaml :ref:`mappings <yaml-format-collections>` are basically associative arrays. You can instruct the parser to return
+mappings as objects (i.e. ``\stdClass`` instances)::

+    $object = Yaml::parse('{"hello": "world"}', false, false, true);
+    echo get_class($object); // stdClass
+    echo $object->hello; // world
