废话不多说，直接上图：
作为一个优雅的Minecraft服务器，肯定需要官网的嗯。
很多服务器的官网都有显示当前服务器在线人数，延迟，每一个子服在线人数，甚至出了个流量图。
我们不搞花里胡哨的查询人数，直接用最简单的代码去完成一个简约的人数查询。
很好，让我们来搞吧！
首先我们需要引用一个外部PHP文件。
名字可以起做STATUS.CLASS.php
然后里面加入如下代码：
1 <?php

很好，我们继续。
再新建一个php文件，名字和上面一样随意。然后复制如下代码到里面。
<?php
include_once ‘status.class.php‘;
$status = new MinecraftServerStatus(); // 类
$response = $status-> getStatus(‘s1.devicloud.cn‘, 25565); // 服务器地址
if(!$response) {
echo"服务器可能离线!";
} else {
echo"".$response[‘players‘]."";
}
?>
好，就这样。
其中include_once ‘status.class.php‘;
是上面引用PHP库的相对路径。
如果那个PHP库在同级目录的libraries文件夹下，那就应该这样写：
include_once ‘/libraries/status.class.php‘;
然后就可以在你的网页内调用这段代码啦！
调用：
