Subdomains can be retrieved with .htaccess (you need however wildcard mentioned earlier in this thread):

RewriteEngine On
RewriteCond %{HTTP_HOST} ^user([0-9]{1,10}).domain.name$
RewriteRule ^.*$ index.php?subdomain=%1

I would simply use a wildcard to point all subdomains to a certain directory and have a front controller there that determines the used one from the URL - this is the easiest and safest solution from PHP.

EDIT Then you can obviously check whether that one should be existing (store them in a database or whatever) etc.
