它在Localhost中工作但它在我的主机中不起作用？ （youtube-mp3.org链接）

Question

我正在安装此链接：youtube-mp3.org download class

//使用php

<?php 
include ('youtubetomp3.php');
echo $link = YoutubeToMP3::get('http://www.youtube.com/watch?v=tGa5-nojscY', YoutubeToMP3::DOWNLOAD);
?>

可能是这些问题;

• a-）是因为youtube-mp3.org还是我的托管？

• b-）是因为$ currentTime = time（）;

• c-）是因为$ requestId = $ itemInfo [＆＃39; h＆＃39;];

Answer 1

根据您在评论中提到的日志中的错误，您需要设置safe_mode = Off并删除open_base_dir文件中php.ini行。如果您无法访问php.ini文件，请要求您的托管服务提供商执行此操作。

Answer 2

这是因为ip adress.Youtube-MP3.org在他们的下载链接中使用info.h.info.h为用户的IP地址生成，下载链接仅属于连接器用户因此，你无法与其他用户分享。很明显，在网站上，服务器使用自己的ip地址并从youtubemp3获取自己的ip地址链接，用户无法使用它。但是在localhost服务器和用户＆＃ 39; s ip地址相同，所以php运行正常。
