-    different YAML strings.

-It may also be convenient to use the

-    $yaml = Yaml::parse(file_get_contents('/path/to/file.yml'));

-The :method:`Symfony\\Component\\Yaml\\Yaml::parse` static method takes a YAML
-string or a file containing YAML. Internally, it calls the
-:method:`Symfony\\Component\\Yaml\\Parser::parse` method, but enhances the
-error if something goes wrong by adding the filename to the message.

-The :method:`Symfony\\Component\\Yaml\\Dumper::dump` method dumps any PHP
+The :method:`Symfony\\Component\\Yaml\\Yaml::dump` method dumps any PHP
 array to its YAML representation:
 
 .. code-block:: php
 
-    use Symfony\Component\Yaml\Dumper;
+    use Symfony\Component\Yaml\Yaml;
 
     $array = array(

 If an error occurs during the dump, the parser throws a
 :class:`Symfony\\Component\\Yaml\\Exception\\DumpException` exception.
 
-If you only need to dump one array, you can use the
