    Use wildchar/wildcard DNS ( I.e. *.domain.com > 1.2.3.4 ) and either use the host request header in your PHP scripts to see what was domain accessed, or use mod_rewrite in a .htaccess to do a redirect.

    Your domain host/registrar/reseller will need to support wildchar/wildcard DNS records (and most big ones do). If not you can move your DNS to a more capable provider (and still use your current host, if you like).

    Your host will also need to have support for the wildchar/wildcard sub-domain in their web server config (or maybe a fixed IP address would be an alternative, even if it does cost a bit more).
