php - php は $server などを呼び出さない

Question

プラグインがゆっくりと機能し始めましたが、プラグインを改善して独自のコード (一種) を使用したいと思ったときに、機能しなくなりました。

サイト: minepress co uk

問題: /function.php であるインクルード ファイルから呼び出すのではなく、php をテキストとして表示しています。

関数.php

<?php

class MCServerStatus {


    public $server;
    public $online, $max_players;
    public $error = "OK";



    function __construct($url, $port = '25565') {

        $this->server = array(
            "url" => $url,
            "port" => $port
        );

        if ( $sock = @stream_socket_client('tcp://'.$url.':'.$port, $errno, $errstr, 1) ) {

            $this->online = true;

            fwrite($sock, "\xfe");
            $h = fread($sock, 2048);
            $h = str_replace("\x00", '', $h);
            $h = substr($h, 2);
            $data = explode("\xa7", $h);
            unset($h);
            fclose($sock);

            if (sizeof($data) == 2) {
                $this->motd = $data[0];
                $this->max_players = (int) $data[1];
            }
            else {
                $this->error = "Cannot retrieve server info.";

        else {
            $this->online = false;
            $this->error = "Cannot connect to server.";
        }

    }



}


//$var = $server->online; //$server->online returns true if the server is online, and false otherwise
//echo $server->motd; //Outputs the Message of the Day
//echo $server->online_players; //Outputs the number of players online
//echo $server->max_players; //Outputs the maximum number of players the server allows
//print_r($server); //Shows an overview of the object and its contents. (For debugging.)
