PHP Json Terraria Server Status - php

Question

I really searched a long time on google/stackoverflow and didn't find my answer.
I'm trying to put an image to see if my Terraria server is online or not and if yes, who's connected etc.. :p I'm really noob in php but I'm trying to learn! I got this source code from geek85 on tshock.co . Here's the source :
<?php
error_reporting(E_ERROR);
//variables
$ip = 'XXX.XXX.XXX.XXX';
$port = '7878'; //port of rest server, not terraria server
$json = json_decode(file_get_contents('http://'.$ip.':'.$port.'/status/'), true);
header('Content-Type: image/png');
$im = #imagecreatefrompng('terraria_online.png');
$font = 'visitor1.ttf';
//$font2 = 'fonts/visitor2.ttf';
$red = imagecolorallocate($im, 255, 24, 24);
$blue = imagecolorallocate($im, 50,50,255);
$black = imagecolorallocate($im, 10,10,10);
$purple = imagecolorallocate($im, 127,0,127);
$grey = imagecolorallocate($im, 50, 50, 50);
$white = imagecolorallocate($im, 255, 255, 255);
//server found and running
if ($json['status'] == '200')
{
// text in the grey box
$playerarray = explode(', ',$json['players']);
imagettftext($im, 18, 0, 31, 16, $grey, $font, $json['name']);
imagettftext($im, 18, 0, 30, 15, $red, $font, $json['name']);
imagettftext($im, 14, 0, 31, 34, $grey, $font, 'IP: '.$ip);
imagettftext($im, 14, 0, 30, 33, $black, $font, 'IP: '.$ip);
imagettftext($im, 14, 0, 31, 49, $grey, $font, 'Port: '.$json['port']);
imagettftext($im, 14, 0, 30, 48, $black, $font, 'Port: '.$json['port']);
imagettftext($im, 14, 0, 9, 71, $grey, $font, 'Joueurs en ligne: '.$json['playercount']);
imagettftext($im, 14, 0, 8, 70, $blue, $font, 'Joueurs en ligne: '.$json['playercount']);
// show VIPs' avatar
if ($json['playercount'] > 0)
{
//array of VIP players - (next step : a txt file with names and coordinates to parse...)
$vip = array('QcSeb','Marlin','Twingo','Gaston');
$num = count($vip);
for ($i=0; $i<$num; $i++)
{
if (in_array($vip[$i], $playerarray))
{
$player = #imagecreatefrompng('Images/'.strtolower($vip[$i]).'.png');//This line doesn't work for now
$long = imageSX($player);
$haut = imageSY($player);
switch ($vip[$i])
{
//here, it's a bit difficult: these are the coordinate where to place VIP players in the image.
case 'QcSeb':
$x = 350;
$y = 133;
break;
case 'Gaston':
$x = 300;
$y = 68;
break;
case 'Marlin':
$x = 261;
$y = 68;
break;
case 'Twingo':
$x = 307;
$y = 133;
break;
}
$ok = imagecopy($im,$player,$x,$y-$haut,0,0,$long,$haut);
}
}
// name of players (VIP or not)
$i = -1;
$j = 0;
// since my server only accept 8 players, I don't have any overflow control on the number of player's name to write but this code can do the work for any number of player (< to width of image / 75)
foreach( $playerarray as $player )
{
if ($i++ >= 6)
{
$i = 0;
$j++;
}
imagettftext($im, 11, 0, 11+($j*75), 101+($i*15), $grey, $font, $player);
imagettftext($im, 11, 0, 10+($j*75), 100+($i*15), $purple, $font, $player);
}
}
}
// offline or not "statut == 200"
else
{
$im = #imagecreatefrompng('terraria_offline.png');
imagettftext($im, 18, 0, 11, 31, $purple, $font, 'IP:'.$ip.':'.$port);
imagettftext($im, 18, 0, 10, 30, $grey, $font, 'IP:'.$ip.':'.$port);
imagettftext($im, 42, 17, 16, 131, $purple, $font, 'offline');
imagettftext($im, 42, 17, 15, 130, $black, $font, 'offline');
}
imagepng($im);
imagedestroy($im);
?>
I'm using 000webhost : sebserver.comuf.com (/ServerStatus1.php).
When I go on
http://XXX.XXX.XXX.XXX:7878/status/ I get :
{
"status": "200",
"name": "TShock Server",
"port": "7777",
"playercount": "1",
"players": "QcSeb"
}
Because only me is on the server actually.
(XXX.XXX.XXX.XXX = My hidden IP :P)
Here's an example of what I'm trying to do : http://renagadez.square7.de/gen.php?ip=111.111.111.111&port=1111
Thanks for your help in advance!
