Simple PHP Letter Error. Please Help

General PHP Help
#1

I have been working on trying to fix a code I got from a friend. We host CounterStrike servers together, and I cannot seem to figure out this problem.

Hopefully someone here can help.

The code I have been working on is here.
http://184.154.138.58/test3.php?ip=184.154.138.58&port=36965

It is a code that displays server info that anyone can view.

However, if you look at the third line down, you will see

cZ» Sparta

I do not know why this “A” is there. It should be,

cZ» Sparta

Could anyone please help me?

I would appreciate any help or information as to why this error keeps occurring.
