PHP Server Queries Useful?

[jay209015]

Well, after doing some research. I've come up with this little piece of PHP code:

Code: (php) [Select]

<?php
function source_query($ip){
    $cut = explode(":", $ip);
    $HL2_address = $cut[0];
    $HL2_port = $cut[1];
$HL2_stats = '';
$results = array();

    $HL2_command = "\377\377\377\377TSource Engine Query\0";
    
    $HL2_socket = fsockopen("udp://".$HL2_address, $HL2_port, $errno, $errstr,3);
    fwrite($HL2_socket, $HL2_command); 
    $JunkHead = fread($HL2_socket,4);
    $CheckStatus = socket_get_status($HL2_socket);
if($CheckStatus["unread_bytes"] == 0)return 0;

$i = 1;
    while($i){
        $str = fread($HL2_socket,1);
        $HL2_stats .= $str;
        $CheckStatus = socket_get_status($HL2_socket);
        if($CheckStatus["unread_bytes"] == 0){
               $i = 0;
        }
    }
fclose($HL2_socket);

$HL2_stats = substr($HL2_stats,1);
$HL2_stats = explode('|||',urldecode(str_replace(array('%07', '%00'),array('','|||'),urlencode($HL2_stats))));
foreach($HL2_stats as $k => $v){
switch($k){
case '0':
$results['hostname'] = $v;
case '1':
$results['map'] = $v;
case '2':
$results['game'] = $v;
case '3':
$results['gamemode'] = $v;
}
}
return $results;
}
?>

<?php
$ip = '74.193.56.8:27015';
$results = source_query($ip);
foreach($results as $k => $v){
echo $k. ' = ' .$v. '<br />';
}
?>

Which in the browser, returns this result:

Code: [Select]

hostname = Jay209015 Dev Server
map = gm_flatgrass
game = garrysmod
gamemode = sandbox
I don't know if this is useful or not, but I have a feeling a lot more can be done with this. I just don't fully understand these server queries.

Now that there are/will be linux binaries, a self-monitoring script would be good to tell if the server had locked up rather than actually crashing. If locked up, kill the process, then restart the server.
(actually I guess this could be done for Windows too, but linux by default has more scripting languages included)
Megiddo had code at one time that would do that when we hosted a gmod server. Problem is, I think the server queries changed and the script broke.
Or something like that.

Your PHP code bit is a good sample bit.
It's probably basically the same that many of the server signature status sites use, then mix with the PHP image module to make them.

Well, made a few more updates. Version number, dedicated(bool), and OS:

Code: (php) [Select]

<?php
function source_query($ip){
    $cut = explode(":", $ip);
    $HL2_address = $cut[0];
    $HL2_port = $cut[1];
$HL2_stats = '';
$results = array();

    $HL2_command = "\xFF\xFF\xFF\xFFTSource Engine Query\x00";
    
    $HL2_socket = fsockopen("udp://".$HL2_address, $HL2_port, $errno, $errstr,3);
    fwrite($HL2_socket, $HL2_command); 
    $JunkHead = fread($HL2_socket,4);
    $CheckStatus = socket_get_status($HL2_socket);
if($CheckStatus["unread_bytes"] == 0)return 0;

$i = 1;
    while($i){
        $str = fread($HL2_socket,1);
        $HL2_stats .= $str;
        $CheckStatus = socket_get_status($HL2_socket);
        if($CheckStatus["unread_bytes"] == 0){
               $i = 0;
        }
    }
fclose($HL2_socket);

$HL2_stats = substr($HL2_stats,1);
$HL2_stats = explode('|||',urldecode(str_replace(array('%07', '%00'),array('','|||'),urlencode($HL2_stats))));
foreach($HL2_stats as $k => $v){
switch($k){
case '0':
$results['Hostname'] = $v;
case '1':
$results['Map'] = $v;
case '2':
$results['Game'] = $v;
case '3':
$results['Gamemode'] = $v;
case '5':
if(substr($v,0,1) == 'd'){
$results['Dedicated'] = 'True';
}else{
$results['Dedicated'] = 'False';
}
if(substr($v,1,1) == 'w'){
$results['OS'] = 'Windows';
}else{
$results['OS'] = 'Linux';
}
case '7':
$results['Version'] = $v;
}
}
return $results;
}
?>

<?php
$ip = '74.193.56.8:27015';
$results = source_query($ip);
foreach($results as $k => $v){
echo $k. ' = ' .$v. '<br />';
}
?>
Output:

Code: [Select]

Hostname = Jay209015 Dev Server
Map = gm_flatgrass
Game = garrysmod
Gamemode = sandbox
Dedicated = False
OS = Linux
Version =
1.0.0.76

I already made this and released it on the forums, search for SrcQR.

     Lol, and I thought I was making something new

[jay209015]

Either way, I think I'm about to start working on a CMS for ULX. You're classes will make this a lot easier, so we'll see how this turns out.

[Megiddo]

Sounds fun

[jay209015]

My question is, what all should this CMS do?

Currently thinking of a scoreboard style display with a drop down on each for: kick, ban, adduser, pm, gimp....ect...
Group, Adverts, Bans, and MOTD management.
Couple of small features like average ping/players and server activity based on times of the day.
Auto map changer for times of the day.
Chat logging.
Perhaps a ulx autoresponse for help...?

Open to more suggestions.

Template, what do y'all think?

[Megiddo]

Looks nice. Are you making all tabs load with page (javascript)? Or does it fetch a new page when you click on a tab (PHP)? I think it'd be snazzy if you made them all load at once so you could switch between them easily, but I guess that largely depends on what you're going to put in those tabs and how big the contents are.

[jay209015]

I'm going to load them all with javascript.

Edit: at least that's the plan

[Rambomst]

It looks good. I am currently in the process of making my own query script so far it looks like this I am going to be adding some ajax to make it refresh the stats every like 5 seconds and I need to style the player lists a little bit/fix some coding bugs here and there.

[jay209015]

How are you queries running so fast?

[Rambomst]

My webserver and gaming servers are hosted in the same rack and I query them using a local IP maybe that is why.

[jay209015]

Would you mind sharing some code?
