title: Yii: requiring a .php file
body: <p>I develop a project with Yii.</p>
  
  <p>I need to require a plain .php file (not component, not a class, just a regular sequence of PHP functions definitions). What is the correct way to do this under Yii framework? Should I use plain require_once()?</p>
  
  <pre>require_once(Yii::app()->basePath . '/extensions/my-php-file.php');</pre>
  
  <p>Right?</p>
