匹配控制器名称和呼叫特定功能

Question

I've created a class called Router that import all the controller like this:

<?php

 include dirname(dirname(__FILE__)) . '\application\controllers\backend.php';

 class Router
 {
    private $_backend;

    public function __construct()
    {
       $this->_backend = new Backend();
    }

    /**
    * Execute function
    */

    public function submit($controller, $func)
    {
      // $this->_backend->index(); 
     } 
 }

?>

now this class is available in my router.php file, this file is included before anyone else, and I can access to the router class in any php files by reference:

$router = new Router();

my task is call a function index available in backend controller imported in router.php file. In index.php file I have:

$router->submit('backend', 'index');

How I can match the controller name and call the function passed as parameter with the variable inside my Router class?

<?php
 class Router
 {
    public function submit($controller, $func)
    {
      // include dynamically the needed file
      include dirname(dirname(__FILE__)) . '\application\controllers\' . $controller . '.php';
      // The classname starts with capital
      $Class = ucfirst($controller);
      // create an instance
      $ctr = new $Class();
      // and call the requested function
      $ctr->$func();
     } 
 }
