Does anyone have any good script or know of any scripts for subdomains using PHP? Any tutorials would be good to. Thanks

What do you want to do with php and subdomains?

I wrote this to detect the subdomain, for me it works:

$HTTP_HOST = getenv("HTTP_HOST");
ereg("(www.)?([^{.]).([^.]).([^.]{2,5})",} $HTTP_HOST, $regs)

$regs[2] contains the subdomain after running those two lines.

(just if you'rewondering: {2,5} is used because of my local, internal domain "local")
