Talkupation: CrazeDizzleD will become famous soon enough
I'm trying to make a game server monitor. This script works perfectly well on my localhost (using AppServ as my WAMP), but does not work when I upload to my hosting. I have two hosting accounts with different companies and it doesn't work for either, and I get the same error.

The error is "Buffer Empty!", which means it's not reading/writing the information.

Any help would be awesome, thanks.

Here is my source:

Code:
<body bgcolor='#000000'>

<?php

$ip = '8.9.9.13'; // Server IP
$port = '28960';  // Server Port

$cellColor   = '#101010'; // Cell Background Color
$borderColor = '#9d9d9d'; // Table Border Color
$fontColor   = '#ffffff'; // Text Color

$width = '300px'; // Overall Table Width

print '<style type="text/css">
.gentext {
    font-family: serif;
    color: '.$fontColor.';
    font-size: 12pt;    
    }

.infotable {
    border: 1px;
    border-style: solid;
    border-width: thin;
    border-color: '.$borderColor.';
    border-collapse: collapse;
    }
</style>';

$challenge = "\xFF\xFF\xFF\xFFgetstatus";

$fp = @fsockopen ('udp://'.$ip, $port, $errno, $errstr, 1);

if (!$fp) {
    print 'Connection Refused!';
}

stream_set_timeout  ($fp, 1, 0);
stream_set_blocking ($fp, true);

fwrite ($fp, $challenge);

$buffer = fread ($fp, 4096);

fclose ($fp);

if (!$buffer) {
    print 'Buffer Empty!';
}

$rawdata = explode ("\n", $buffer);

array_pop ($rawdata);

$rawitem = explode ("\\", $rawdata[1]);

foreach ($rawitem as $key => $value) {
$value             = strtolower ($value);
$value             = preg_replace ("/\^./", "", $value);
$rawitem[$key + 1] = preg_replace ("/\^./", "", $rawitem[$key + 1]);

$setting[$value]   = $rawitem[$key + 1];
}

$data['gamemod']    = $setting['gamename'];
$data['hostname']   = $setting['sv_hostname'];
$data['mapname']    = $setting['mapname'];
$data['players']    = $rawdata[2] ? count($rawdata) - 2 : 0;
$data['maxplayers'] = $setting['sv_maxclients'];
$data['password']   = $setting['g_needpass'];
$data['gametype']   = $setting['g_gametype'];
$data['version']    = $setting['shortversion'];

array_shift ($rawdata);
array_shift ($rawdata);

foreach ($rawdata as $key => $value) {
preg_match("/(.*) (.*) \"(.*)\"/", $value, $match);

$player[$key + 1]['score'] = $match[1];
$player[$key + 1]['ping']  = $match[2];
$player[$key + 1]['name']  = $match[3];
$player[$key + 1]['name'] = preg_replace ("/\^./", "", $player[$key + 1]['name']);

}

Also print out what is contained in your error variables, that is what they are for and it is called debugging.

I removed the @ and printed errno and errstr. errno returned "0", and errstr returned nothing.

It is connecting fine. The problem comes when I try to read/write the information.

Thanks, but that does the same thing. It works on my localhost but not on my webhost.

This is what I get.
