:raw-html:`<a href="https://github.com/phalcon/cphalcon/blob/master/phalcon/config/adapter/yaml.zep" class="btn btn-default btn-sm">Source on GitHub</a>`

Reads YAML files and converts them to Phalcon\\Config objects.  Given the following configuration file:  

.. code-block:: php

    <?php

     phalcon:
       baseuri:        /phalcon/
       controllersDir: !approot  /app/controllers/
     models:
       metadata: memory

  You can read it as follows:  

.. code-block:: php

    <?php

     define('APPROOT', dirname(__DIR__));
    
     $config = new Phalcon\Config\Adapter\Yaml("path/config.yaml", [
         '!approot' => function($value) {
             return APPROOT . $value;
         }
     ]);
    
     echo $config->phalcon->controllersDir;
     echo $config->phalcon->baseuri;
     echo $config->models->metadata;
