    Hello,

    I have wildcard DNS enabled at my host so that any subdomain points to my main domain directory. I want to make a script that shows the appropriate content for the requested subdomain but the problem is:

    How can I find out (using PHP) what subdomain was requested by the user and so show the right content corresponding to the requested subdomain?

    Use $_SERVER['HTTP_HOST'] and remove your actual domain from it.

    Or if there are not dots in the subdomain, you can do:
    
$subdomain = current(explode('.', $_SERVER['HTTP_HOST']));
