thanks Colin.

Your code very useful for me!

Code:

// All the controller
$arr_controller = array('welcome','user','blog');

list($i, $j, $check) = explode('/', $_SERVER['REQUEST_URI']);

// See if we found a match to our $langs
if (!in_array($check, $arr_controller))
{
    $route['(.*)'] = 'user/id/$1';
}

please correct my code if it wrong. thanks.
