I have two subdomains pointing to the same index.php3. How can I find out which subdomain was entered by the user?

Use the HTTP Host variable (in PHP, this shows up as $HTTP_HOST).  
That'll tell you whether the user is looking at site1.mydomain.com or 
site2.mydomain.com (or even www.myotherdomain.com).
