Well, in your example, $_SERVER['SERVER_NAME'] will be set to subd.domain.com so you could do something like:

<?php
     
     $mainDomain = 'domain.com';
     $subDomain = substr($_SERVER['SERVER_NAME'],0,(0-strlen($mainDomain)-1));
     
     echo \"Main Domain = $mainDomain \n\";
     echo \"Sub Domain = $subDomain \n\";
     
 
?>

Now as to how to set up the server so all subdomains dns settings send you to your main domain, I'm not sure about.
