Auto-loading Resources

###################### 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.
