PHP Serverstatus not updating

[Webtimize]

Hello everyone,

I'm currently working with a serverstatus script found on OTLand, but it's not working propperly.Even while the server is online, it keeps saying that it isn't.

The fun part is, when I restart the server and refresh the page, it'll say that the server is online.When pressing F5 once again, it comes up with server offline.

Config settings;

$server = array();
$server['host'] = '31.xxx.xxx.xx';
$server['port'] = '7171';

general.class.php;

class general {

    public function xml2array( $xmlObject, $out = array ()){
        foreach ( (array) $xmlObject as $index => $node ){
            $out[$index] = ( is_object ( $node ) ) ? self::xml2array ( $node ) : $node;
        }
        return $out;
    }
  
    public function getServerInformation($host, $port){
        $info = chr(6).chr(0).chr(255).chr(255).'info';
        $sock = @fsockopen($host, $port, $errno, $errstr, 1);
        if ($sock){
            fwrite($sock, $info);
            $data = '';
            while (!feof($sock))
                $data .= fgets($sock, 4096);
              
            fclose($sock);
            $XML = @simplexml_load_string($data);
            if($XML)
                return $XML;
        }
        return false;
    }

}

serverStatus.php;

<?php
    $xmlFile = $general->getServerInformation($server['host'], $server['port']); 
    if($xmlFile) {
        $information = $general->xml2array($xmlFile);
      
        if( $information['players']['@attributes']['online'] < 1) {
            echo '<span style="color: green;">There are no players online right now.</span>';
        }
        else {
            echo '<span style="color: green;">There are currently '. $information['players']['@attributes']['online'] .' players online.</span>';
        }      
    }
    else {
        echo '<span style="color: orange;">The server is offline.</span>';
    }
?>

I hope someone can help me, thanks in advance.
