Server Status Block

Hi, I have a script that will display the status of a game server and list the players on it. I tried to put it in a block, but none of the data is showing. Here's the block's code:

Code:

<?php

$server = "69.112.33.45";
$port = "28001";

function CantConn()
{
$content = "<table border=\"1\" align=\"left\" style=\"border-collapse: collapse\" width=\"100%\" id=\"table1\"><tr><td><B>Connection Error: Server Link Down</B></td></tr></table>";
}

function getData($server, $port, $retrying='1')
{
$input = Chr(98).Chr(0).Chr(0);
@$fp = fsockopen('udp://'.$server, $port);
stream_set_timeout($fp, (0.5*$retrying));
if(!$fp)
CantConn();

fputs($fp, $input);
$out = fopen('./serverDump.txt', 'a+');
$output;
for($problem = stream_get_meta_data($fp);!$problem[timed_out];$problem = stream_get_meta_data($fp))
$output .= fread($fp, 2048);
fclose($fp);

if(!displayData($output))
{
if($retrying == 2)
CantConn();
else
getData($server, $port, ($retrying+1));
}

return true;
}

function displayData($data)
{
$header = substr($data, 0, 4);
if($header != chr(99).chr(0).chr(0).chr(98))
return false;

$game = substr($data, 5, 6);
$rest = substr($data, 11);

$verC = ord(substr($rest, 0, 1));
$version = substr($rest, 1, $verC);
$rest = substr($rest, $verC+1);

$nameC = ord(substr($rest, 0, 1));
$name = substr($rest, 1, $nameC);
$numPL = ord(substr($rest, $nameC+3, 1));
$maxPL = ord(substr($rest, $nameC+4, 1));
$rest = substr($rest, $nameC+7);

$modCount = ord(substr($rest, 0, 1));
$mod = substr($rest, 1, $modCount);
$rest = substr($rest, $modCount+1);

$mapTC = ord(substr($rest, 0, 1));
$mapType = substr($rest, 1, $mapTC);
$rest = substr($rest, $mapTC+1);

$mapNC = ord(substr($rest, 0, 1));
$mapName = substr($rest, 1, $mapNC);
$rest = substr($rest, $mapNC+1);

$servDC = ord(substr($rest, 0, 1));
$servDetail = substr($rest, 1, $servDC);
$teams = ord(substr($rest, $servDC+1, 1));
$rest = substr($rest, $servDC+2);

//== Time to chop off all other stuff, starting from teams...
$b1c = ord(substr($rest, 0, 1));
$rest = substr($rest, $b1c+1);
$b2c = ord(substr($rest, 0, 1));
$rest = substr($rest, $b2c+1);

//== Getting team names
$teamName[255] = "Observer"; //== ALWAYS
for($i = 0; $i < $teams; $i++)
{
$teamNC = ord(substr($rest, 0, 1));
$teamName[$i] = substr($rest, 1, $teamNC);
$rest = substr($rest, $teamNC+1);
$chopC = ord(substr($rest, 0, 1));
$rest = substr($rest, $chopC+1);
# echo("$i: $chopC : ".substr($rest, 0, 1)).' ';
}

$playerName;
$playerTeam;
$playerPing;
$playerPL;
for($i = 0; $i < $numPL; $i++)
{
$playerPing[$i] = ord(substr($rest, 0, 1))*4;
$playerPL[$i] = ord(substr($rest, 1, 1));
$playerTeam[$i] = ord(substr($rest, 2, 1));
$playerNC = ord(substr($rest, 3, 1));
$playerName[$i] = substr($rest, 4, $playerNC);
$rest = substr($rest, (4+$playerNC));
$chopC = ord(substr($rest, 0, 1));
$rest = substr($rest, $chopC+1);
}

$content = "<table border=\"1\" align=\"left\" style=\"border-collapse: collapse\" width=\"100%\" id=\"table1\"><tr><td><B>$name</B><br /><B>$numPL</B> / <B>$maxPL</B> players</td></tr>";

$content = "<tr><td><U><B>Player:</B></U></td></tr>";

for($i = 0; $i < $numPL; $i++)
$content = "<tr><td>$playerName[$i]</td></tr>";
$content = "</table>";

return true;
}

function a($in)
{
$out = $in;
return $out;
}

$server = $_GET['server'];
$port = $_GET['port'];

// Generate Page
//makeForm($server,$port);
if($server && $port)
{
?>
<br>
<?php
getData($server, $port);
}
?>

I know I'm missing the protection part, I'll add it in when I get this working.

Thanks.

Only the first $content needs to be equal
The subsequent ones need to add a period - this tells it to append

Quote:

$content .=

Ok, did that. It's still showing as if there's no content.
