Bleh. Not interesting.
No, this is wrong.

This program is based on IP address which comes "without network load cost" from the HTTP $_SERVER['REMOTE_ADDR'] global PHP var.

Basically, the server simply takes the REMOTE_ADDR (IP address) and queries a file on the same server (can download file for free) and returns country information.

This is a great feature for many forums that would like to display different content to the user based on country.
