PHP使用FTP转移文件夹以及子文件夹

项目需要通过php调用ftp转移一个文件夹以及所有的内容到另一台服务器，刚听到这个需求，简直是一头雾水，可是php就是php，ftp被默认支持了。于是谷歌了一下ftp的知识，看了看php的api，有了个不怎么完美的解决方案。

不知道为啥，在自己的ftp服务器运行良好，换做公司的服务器就悲剧的挂掉了，真心不解，难道是不同的ftp服务器支持的不一样？

于是出现了下面的版本。只是把传输文件放在了遍历文件夹的方法里面了，结果还是比较欣慰的。只是如果文件大了，速度很慢不说，还会出点问题。真正到服务器的文件比原先的文件少了那么一点点。迷茫了。有高手可以指点一下吗？
