Run another function in controller class - Background process

You might be able to do something like this in your Main index function, but play around with the code, I haven't tested it.

Code:

public function index()
{
   include('path/to/otherController.php');
   $controllerObj = new ControllerName();

   call_user_func(array($controllerObj, 'index'));
}
