DiscuzX3 Open Mobile version, access to the site will automatically determine whether it comes from the desktop or mobile, how is it done?

Is it a judgment done in PHP, or is it done in Web server?
Is it in the index.php? This file has been processed in front of the host, but does not see the logic associated with the user agent. Want to ask the discuzX3 is where, how to make a judgment?
Thank you ~
