I know that everyone has their own method of doing things. I thought it would be a cool idea to to do it myself and add a bit more functionality to the script itself. I've never messed with sockets in PHP before but here is my take on it:
Using the Class:
The information that it retrieves is the following:
If you need any help, just leave a comment and I'll give you a hand.
Note:
This will not work on a web server unless you own your own because of the firewall that they use and the fact that the connection is UDP. This goes for all of these scripts. The firewall blocks the UDP packets the server returns because the connection in the PHP is not persistent.
PHP Code:
