there's 2 parts this. firstly you'll need setup wildcard dns entry.

once you've got setup should have requests pointed single domain. there can use php figure out domain you're on:

$domain = $_server['http_host']; $base = 'mydomain.com'; $user = substr($domain, 0, -(strlen($base)+1));// user part of domain if(!empty($user)) {   $user = sanatiseuser($user);   require_once $user.'.php'; }
