PHP Server Queries Useful?

[jay209015]

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

Code: PHP

1. <?php
2. function source_query($ip){
3.     $cut = explode(":", $ip);
4.     $HL2_address = $cut[0];
5.     $HL2_port = $cut[1];
6.         $HL2_stats = '';
7.         $results = array();
8.  
9.     $HL2_command = "\377\377\377\377TSource Engine Query\0";
10.    
11.     $HL2_socket = fsockopen("udp://".$HL2_address, $HL2_port, $errno, $errstr,3);
12.     fwrite($HL2_socket, $HL2_command);
13.     $JunkHead = fread($HL2_socket,4);
14.     $CheckStatus = socket_get_status($HL2_socket);
15.         if($CheckStatus["unread_bytes"] == 0)return 0;
16.        
17.         $i = 1;
18.     while($i){
19.         $str = fread($HL2_socket,1);
20.         $HL2_stats .= $str;
21.         $CheckStatus = socket_get_status($HL2_socket);
22.         if($CheckStatus["unread_bytes"] == 0){
23.                $i = 0;
24.         }
25.     }          
26.         fclose($HL2_socket);
27.        
28.         $HL2_stats = substr($HL2_stats,1);
29.         $HL2_stats = explode('|||',urldecode(str_replace(array('%07', '%00'),array('','|||'),urlencode($HL2_stats))));
30.         foreach($HL2_stats as $k => $v){
31.                 switch($k){
32.                         case '0':
33.                                 $results['hostname'] = $v;
34.                         case '1':
35.                                 $results['map'] = $v;
36.                         case '2':
37.                                 $results['game'] = $v;
38.                         case '3':
39.                                 $results['gamemode'] = $v;                     
40.                 }
41.         }
42.         return $results;
43. }
44. ?>
45.  
46. <?php
47. $ip = '74.193.56.8:27015';
48. $results = source_query($ip);
49. foreach($results as $k => $v){
50.         echo $k. ' = ' .$v. '<br />';
51. }
52. ?>

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

1. <?php
2. function source_query($ip){
3.     $cut = explode(":", $ip);
4.     $HL2_address = $cut[0];
5.     $HL2_port = $cut[1];
6.         $HL2_stats = '';
7.         $results = array();
8.  
9.     $HL2_command = "\xFF\xFF\xFF\xFFTSource Engine Query\x00";
10.    
11.     $HL2_socket = fsockopen("udp://".$HL2_address, $HL2_port, $errno, $errstr,3);
12.     fwrite($HL2_socket, $HL2_command);
13.     $JunkHead = fread($HL2_socket,4);
14.     $CheckStatus = socket_get_status($HL2_socket);
15.         if($CheckStatus["unread_bytes"] == 0)return 0;
16.        
17.         $i = 1;
18.     while($i){
19.         $str = fread($HL2_socket,1);
20.         $HL2_stats .= $str;
21.         $CheckStatus = socket_get_status($HL2_socket);
22.         if($CheckStatus["unread_bytes"] == 0){
23.                $i = 0;
24.         }
25.     }          
26.         fclose($HL2_socket);
27.        
28.         $HL2_stats = substr($HL2_stats,1);
29.         $HL2_stats = explode('|||',urldecode(str_replace(array('%07', '%00'),array('','|||'),urlencode($HL2_stats))));
30.         foreach($HL2_stats as $k => $v){
31.                 switch($k){
32.                         case '0':
33.                                 $results['Hostname'] = $v;
34.                         case '1':
35.                                 $results['Map'] = $v;
36.                         case '2':
37.                                 $results['Game'] = $v;
38.                         case '3':
39.                                 $results['Gamemode'] = $v;
40.                         case '5':
41.                                 if(substr($v,0,1) == 'd'){
42.                                         $results['Dedicated'] = 'True';
43.                                 }else{
44.                                         $results['Dedicated'] = 'False';
45.                                 }
46.                                 if(substr($v,1,1) == 'w'){
47.                                         $results['OS'] = 'Windows';
48.                                 }else{
49.                                         $results['OS'] = 'Linux';
50.                                 }
51.                         case '7':
52.                                 $results['Version'] = $v;                              
53.                 }
54.         }
55.         return $results;
56. }
57. ?>
58.  
59. <?php
60. $ip = '74.193.56.8:27015';
61. $results = source_query($ip);
62. foreach($results as $k => $v){
63.         echo $k. ' = ' .$v. '<br />';
64. }
65. ?>

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.

[jay209015]

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.

Would you mind sharing some code?
