    You're not trying to call a global function, you're trying to call a class method, so use $this: class Controller{ function display($template){ $this->display('error'); } } Commented May 21, 2015 at 11:07

    Now sits back and waits for the stackoverflow from the recursive call Commented May 21, 2015 at 11:09
  • @MarkBaker made my day, of course this function causes an stackoverflow error, I just cut the unecessary parts, now it works. Commented May 21, 2015 at 11:10
  • also refer self vs $this Commented May 21, 2015 at 11:13

}

You have to use $this or self - 

class Controller{
    function display($template){
        $this->display('error');
    }
}

Or use - self::display('error');
