PHP Query (show your server on your website)
#1

This code is originally made by Peter, as shown in the credits.
I've changed some small bits to make it 0.3 compatible, and here it is.
An example can be found at https://www.serverffs.com/dump/query.php

This works on PHP 5 only, if you have PHP 4 you should just update to PHP 5 which got released 6 years ago.
If you have shared webhosting, tell your provider to update or switch to a modern provider.


Usage:
Code:
<?php
require "samp_query.php";

$serverIP = "91.121.209.20";
$serverPort = 7777;

try
{
    $rQuery = new QueryServer( $serverIP, $serverPort );

    $aInformation = $rQuery->GetInfo( );
    $aServerRules = $rQuery->GetRules( );
    $aBasicPlayer = $rQuery->GetPlayers( );
    $aTotalPlayers = $rQuery->GetDetailedPlayers( );

    $rQuery->Close( );
}
catch (QueryServerException $pError)
{
    echo 'Server is offline';
}

if(isset($aInformation) && is_array($aInformation)){
?>
  <b>General Information</b>
  <table width="400">
      <tr>
          <td>Hostname</td>
          <td><?php echo htmlentities($aInformation['Hostname']); ?></td>
      </tr>
      <tr>
          <td>Gamemode</td>
          <td><?php echo htmlentities($aInformation['Gamemode']); ?></td>
      </tr>
      <tr>
          <td>Players</td>
          <td><?php echo $aInformation['Players']; ?> / <?php echo $aInformation['MaxPlayers']; ?></td>
      </tr>
      <tr>
          <td>Map</td>
          <td><?php echo htmlentities($aInformation['Map']); ?></td>
      </tr>
      <tr>
          <td>Weather</td>
          <td><?php echo $aServerRules['weather']; ?></td>
      </tr>
      <tr>
          <td>Time</td>
          <td><?php echo $aServerRules['worldtime']; ?></td>
      </tr>

          <td>Version</td>
          <td><?php echo $aServerRules['version']; ?></td>
      </tr>
      <tr>
          <td>Password</td>
          <td><?php echo $aInformation['Password'] ? 'Yes' : 'No'; ?></td>

  <?php
  if(!is_array($aTotalPlayers) || count($aTotalPlayers) == 0){
      echo '<br /><i>None</i>';
  } else {

	      </tr>
	  <?php

Instead of <?php ?> lots of time, Add one at Top of the Script and End of the script, could be better :P

Don't comment uselessly. Doing so in that method would waste time, him terminating the document parsing as PHP and reverting to HTML is what saves him having to add backslashes after every quote (single or double) in an echo(). Also, having to process the backslashes is more intensive.

Woet is quite awesome at PHP Coding, but I was just giving him a small suggestion.

It's a useless suggestion - When you try suggesting something; maybe you should actually provide a useful reply.

Then you are simply doing it wrong, it works perfectly.

When outputting a lot of HTML, it's cleaner and easier to simply close PHP tags and open them later.

Well all i have done is copy and pasted the code that you have done and saved them as PHP

Parse error: syntax error, unexpected '{' in .../index.php on line 8

and 8 is { lol?

Code:
7: 
8: try
9: {
10:    $rQuery = new QueryServer( $serverIP, $serverPort );
11:
12:    $aInformation = $rQuery->GetInfo( );
[test it on a 0.3 server, not on my own (since its 0.2)]

Forgot to mention, this only works with PHP 5 and up (you know, that version that got released 6 years ago).
