###################### Auto-loading Resources ###################### CodeIgniter comes with an "Auto-load" feature that permits libraries, helpers, and models to be initialized automatically every time the system runs. If you need certain resources globally throughout your application you should consider auto-loading them for convenience. The following items can be loaded automatically: - Classes found in the *libraries/* directory - Helper files found in the *helpers/* directory - Custom config files found in the *config/* directory - Language files found in the *system/language/* directory - Models found in the *models/* folder To autoload resources, open the **application/config/autoload.php** file and add the item you want loaded to the autoload array. You'll find instructions in that file corresponding to each type of item. .. note:: Do not include the file extension (.php) when adding items to the autoload array. Additionally, if you want CodeIgniter to use a `Composer <https://getcomposer.org/>`_ auto-loader, just set ``$config['composer_autoload']`` to ``TRUE`` or a custom path in **application/config/config.php**.
