【问题描述】：
你好，我告诉他们我有以下问题： 我有 2 个文件，这是 php 中的一个类，另一个是调用此类并显示结果的脚本，有趣的是，在我的计算机上，localhost 在其他具有 php 5.4 的服务器上也可以正常运行，但在 hostmonster只工作了一天，第二天就停止工作了，我提供支持并说这是我的事情，队列错误代码给我的是：
PHP 注意：未定义变量：导致 /home/user/public_html/rox.php 在第 25 行
对 rox.php 进行编码
<?php
// use the IceCast class to obtain the stream details
require_once('icecast.php');
$oIceCast = new IceCast();
// set server and mount
$server = 'http://giss.tv:8000';
$file = '/status.xsl?mount=/radiosuguaFM.mp3';
$oIceCast->setUrl($server,$file);
$status = $oIceCast->getStatus();
$result .= <<<EOF

此代码 de class icecast.php：
<?php
