>>i have tecks vbhome (lite) installed so that is my ROOT index.php, should i still add the code or can i just put it in like a new file say called index2.php ?

The point is to put the code right on the top of your ROOT index.php. Since that is what most people are after on your domain, that should be as fast and uncluttered as possible. Don't bother including another file or sending it off to process before going to your root index.php--

With this code, it only does a few matching operations then runs as normal, with no database access additions, when people are just going to your normal root index. It should add virtually no overhead unless people are looking for a user's subdomain.
