Does anyone know of a way to detect if the user is coming in via a proxy server using PHP?

Probably the best way that I could think of off the top of my head would be to use $_SERVER['HTTP_X_FORWARDED_FOR']. That usually gives you the local IP address of the user if it is behing a proxy.

Hope this helps.

If the proxy is good enough, you can't tell, in the end.
