Creating an admin area

[eluser]M4rc0[/eluser]
Hello!

Sorry for bumping this but one thing got to my mind:

TheFuzzy0ne posted this interesting code:

Code:

<?php

class MY_Controller extends Controller {
    
    function MY_Controller()
    {
        parent::Controller();

    }
    
    function _admin_restricted_area()
    {
        if (! $this->user->is_admin())
        {
            show_404();
        }
    }
    
    function _user_restricted_area()
    {
        if (! $this->user->is_logged_in())
        {
            redirect('/forums/member/login');
        }
    }
}

May I ask, in your opinion, why extending a controller and not creating a helper with this functions?
Is there any advantages?

Just wondering if I took the right approach.
I'm using a helper with a method "is_logged_in", because then I can use that in my views to display different menus and etc

I would like to hear any opinion
