Extending multiple controllers in Code Igniter

Hi! If you are forced to use old framework like codeigniter, and want to have multiple base controllers and then extend them here a trick you can do:

1) check the value of

$config['subclass_prefix'] = 'MY_';

in application\config\config.php

By default it is MY_ ; but nvm check to make sure.

2) create php file called MY_Controller.php (or your %prefix%Controller.php inside application\core folder

3) In this file (MY_Controller.php) you can create any amount of base controllers that extends CI_Controller, and then in simple controllers extend these base controllers

<?phpif (!defined('BASEPATH')) {    exit('No direct script access allowed');}

class Admin_Controller extends CI_Controller{    }
class Public_Controller extends CI_Controller{
}
