Honestly, this is really good work for being a beginner. The colors on your first design work very well with each other, it could use a tiny bit of improving on the palette of it, it could possibly use some centering but that is simply a preference not a design flaw. On your 2nd design it seems like it needs more dynamics to it's design (maybe some more colors or something); the footer should also extend the whole page. On your 3rd one it could use a different color combination and probably some rounded corners. Great job on the 4th one!
A best practice for PHP: you should always use curly brackets with if statements.
For instance, you had this:
if (! $sock = @fsockopen($ip, $mapport, $num, $error, 5))
echo '<font color="red"><strike>Map Server</strike></font> <b';
When it should be this:
if (! $sock = @fsockopen($ip, $mapport, $num, $error, 5)) {
[TAB]echo '<font color="red"><strike>Map Server</strike></font> <b';
}
