看了半天，原来是自己在函数开始的地方isset写了一个死循环，函数不停的在调用自身。
用html表单提交的方式看到不停的在输出$srcPath;
改成下面这种方式就可以了。

感谢 【CodeIgniter 中国1号】QQ群的帮助， 尤其感谢，曾经很牛，freda，我喂自己袋盐等的热心解答。

多用户的相册管理，需要建立相册表，别名，相册名，路径一一对应等。

这里的这个代码只是针对单一用户的相册操作，并不适用多用户相册管理。

看到楼主写的代码，当复制文件夹的时候，是不是只会复制文件夹，文件夹里面的文件会复制不过去呢?所以我感觉那点用上递归

if(is_dir($srcPath."/".$item)){
    $func=__FUNCTION__;
    $func=($srcPath."/".$item,$desPath."/".$item);
}

,我只是个菜鸟，如有错误，请指教.
