htaccess

how do i use this class file in my server

1. Rewrite all requests, on your script with included htaccess.class.php
Example:
.htaccess
RewriteEngine On
RewriteRule ^([^.]+)$ index.php

2. In your script use $_SERVER['REQUEST_URI'] for call $htaccess->execute ();
Example:
$vdir = $_SERVER['REQUEST_URI'];

$htaccess = new HTAccess ($_GET);

$htaccess->setLine ('RewriteBase /');
$htaccess->setLine ('RewriteRule ^(test1)[/]?$ ?action=$1 [L]');
$htaccess->setLine ('RewriteRule ^(test1/2)[/]?$ ?action=$1&page=2 [L]');

$htaccess->execute ($vdir);

3. Get result works.
Example:
print_r($_GET);

It not works for me.
Just get an simple Output "'Array ( )'" when im calling "http://dev/site/test1/2" on my browser.

Any suggestions?
Thanks a lot fpr the Script!
