I have a domain where I want to use subdomains, but all via files in the root.

I've added a wildcard (*) A dns record on my domain so all subdomains link to the root per default.

Now I want, f.e., test.domain.com link to the root (domain.com/?id=5), but the subdomain has to remain the path. Still get me? (bla.domain.com has to link to domain.com/?id=6)

Like if i go to: http://another.domain.com/members/5/ it links to the members page in the root (members.php?id=5).

I think this is possible via htaccess, but not sure. Anyone?
