Codeigniter : calling a method of one controller from other

Question

I have two controllers a and b.

I would like to call a method of controller a from a method of controller b.

Answer 1

very simple in first controllr call

 $this->load->model('MyController');
 $this->MyController->test();

place file MyController.php to /model patch

MyController.php should be contain

class MyController extends CI_Model {

    function __construct() {
        parent::__construct();
    }
    function test()
    {
        echo 'OK';
    }
}
