PHP：

public function initPath(){
        $path = $_SERVER['PATH_INFO'];
        $lastFix = strrchr($path,'.');
        $path = str_replace($lastFix,'',$path);
        $path = substr($path,1);
        $array = explode('/',$path);
        $lenght = count($array);
        if ($lenght == 1){
            $_GET['m'] = $array[0];
        }elseif ($lenght == 2){
            $_GET['m'] = $array[0];
            $_GET['c'] = $array[1];
        }elseif ($lenght == 3){
            $_GET['m'] = $array[0];
            $_GET['c'] = $array[1];
            $_GET['a'] = $array[2];
        }else{
            $_GET['m'] = $array[0];
            $_GET['c'] = $array[1];
            $_GET['a'] = $array[2];
            for ($i=3;$i<$lenght;$i+=2){
                $_GET[$array[$i]] = $array[$i+1];
            }
        }
    }
