### CzarQuery v1.00

/* #

CzarQuery is made to retrieve information from a Half-Life
server about who is playing, what mod it is running, and
what map the server is currently playing.

This script has been tested with and includes map pictures
for the following mods:
- Counter-Strike
- Day of Defeat
- Natural Selection
- Team Fortress Classic
- Action Half-Life

CzarQuery is based on code by madCoder called madQuery,
and merely provides a way to display the reults given from
his script.  I take no credit for his coding for retrieving the
information from the Half-Life server, but only the credit for
the work done displaying the information.

// Enter your server IP address and port number below
$server_ip = "216.178.199.11";

Display type - Tells script to display as a full page by itself, or as

Accepted values are:

											and generating proper HTML formatting
$page = "include"; - Displays as a lighter version that only displays
														the server information, and requires you to include
														the CSS file in the <head> tags of your header file,
														or to make your own CSS formatting.  Instructions
														on including the CSS file in your own <head> tags
														can be found in the readme.txt in the ZIP package,
														or you may simply place the line:
														<link rel="stylesheet" type="text/css" href="czarquery.css">
														in between your <head> tags

Então amigo esse erro provavelmente ocorre por que você esta usando um servidor "bem configurado"(ou seja php.ini), este código esta bem desatualizado, usa funções de maneira errada, não usa isset, no php4 rodava legal mas no php5 dificilmente vai rodar amigo recomendo buscar uma alternativa.

O problema é nesta linha:

$tmp=fread($this->_sk,1);

$stat=socket_get_status($this->_sk);

$tmp.=fread($this->_sk, $stat["unread_bytes"]);

fread([paramentro 1],[parametro 2]);

provavelmente a variavel $stat["unread_bytes"] esta retornando 0, null ou false e o valor do segundo parametro na função fread não pode ser menor que "1" =/

talvez a função socket_get_status esteja desabilitada, tente fazer isto para ver o que ocorre com ela:

$tmp=fread($this->_sk,1);
$stat=socket_get_status($this->_sk);
echo '<pre>';
print_r($stat);
echo '</pre>';

echo 'stat["unread_bytes"]: ('.$stat["unread_bytes"].')<br>';/*deve retornar 1 ou um numero maior*/
$tmp.=fread($this->_sk, $stat["unread_bytes"]);

coloque o que o teste imprimiu aqui no seu tópico para analizarmos ;)
