Player Faces in Minecraft

<?php
/* DEMO ---------------------------------------------------------------------------------------------------------------------- */

/* This file is a working example, so with a few edits to this file and server.properties and a file or two created (with accurate permissions) on your server, you can be up and running in no time.

You will need to edit server.properties to enable a remote connection in your Minecraft server: 'enable-query=true' amd set a port for querying your server: 'query.port=25565'. You shouldn't use the default port number.

Edit this file just below (the first block of code): YOURSERVER.COM & YOURPORTNUMBER to the URL for your Minecraft server and the port number you specified in server.properties (not your server-port; this one needs to be query.port).

This script needs one file to store the player names in temporarily, and a folder to store their skins, we store player names for 5 seconds by default and skins for 24 hours. We do this to stop overloading your server, and http://minecraft.net/skin/, with pointless requests every few seconds.

Create the file 'players' and a folder named 'skins', both need full access by the server.

Please note that if a player hasn't yet changed their default skin (still Steve) the player thumb will be a missing file. I can't distribute it, so you'll need to grab a copy of the original (say, from a theme) and save it as "skins/default-skin.png" /

You should be all done! Visit this page in your browser, and you should see a list of people currently online. */

/* QUERY --------------------------------------------------------------------------------------------------------------------- */

/* You could use different code to pull from a static file (either one you maintain separately, or whitelist.txt), you don't have to use PHP Minecraft Query, I just prefer it: check out https://github.com/xPaw/PHP-Minecraft-Query/blob/master/view.php.*/

// requiring php-minecraft-query class
require 'MinecraftQuery.class.php';

// connection variable for php-minecraft-query
define( 'MQ_SERVER_ADDR', 'YOURSERVER.COM' ); 
define( 'MQ_SERVER_PORT', YOURPORTNUMBER ); 
define( 'MQ_TIMEOUT', 1 );

// start the query and connect
$Query = new MinecraftQuery( );


/* CACHE --------------------------------------------------------------------------------------------------------------------- */

/* I hide all of this behind a five-second delay so I'm not constantly connecting and querying my server. You're implementation would be different; but something like the following should suffice as a starting point: */

if (filemtime("players") < (time() - 5)) :
  $Query->Connect( MQ_SERVER_ADDR, MQ_SERVER_PORT, MQ_TIMEOUT );
  $players = json_decode(json_encode($Query->GetPlayers())); // yes, this part is stupid. i'm 100% open to suggestions.
  file_put_contents("players", json_encode($players));
else:
  $players = json_decode(file_get_contents("players"));
endif;

/* THUMB --------------------------------------------------------------------------------------------------------------------- */

  // assume by default we don't want to generate a new thumb
  $build = false;

  elseif(filemtime("./skins/".$playa.".png") < time() - (24 * 60 * 60)):
    // if the file is older than a day, generate a new one
    // you can adjust this to your needs: the '24' above represents hours 
    // (48 * 60 * 60) would be two days 
    // (7 * 24 * 60 * 60) would be one week
    // (30 * 24 * 60 * 60) would be a month (sort of)
    $build = true;
  endif;

      // IMPORTANT: you are going to have to supply a copy of this yourself.
      $file = "skins/default-skin.png";

    else:

    // 8 from the top, 8 from the left
    $src_x = 8; // Crop Start X
    $src_y = 8; // Crop Start Y
    // this is how big we want the thumb to be (note it's bigger, stretching will occur. this is intended.)
    $dst_w = 40; // Thumb width
    $dst_h = 40; // Thumb height
    // the face is 8 pixels square in skin.png
    $src_w = 8; // $src_x + $dst_w

Hi, this is a really cool script, but it doesn't generate the players faces, it just takes it from the default skin. When you say there needs to be a "players" file, what type of files does it need to be?
