Hm. Thats interesting. I attempted that the other day, however at that
time it produced results that are... very similar to an infinite loop
(continuously "loading page" on status bar, and when I hit stop the page
had nothing loaded). I expected it to be the same - however it worked
this time, beautifully in fact.

Thanks, you pushed me to try a second time :P

Thats interesting as well, however... I consulted one of my PHP books
for when I was learning the changes in PHP5 and looked at the example
for socket_connect, it shows an example for querying the Return to
Castle Wolfenstein master server, storing the data in an array, and then
without utilizing socket_close in any of the loops - it continues to
conect to each server and query it for its status (players, settings,
etc). That is why I didnt see much error in my code - the example showed
it to be correct in my eyes.

Anyways, yea, thanks for the help!

($ip was set just above that codeblock, for testing purposes I was using
a local IP - 192.168.1.68 to test for functionality.)
