For a long while, the original is in the beginning of the function of the place Isset wrote a dead loop, function constantly in the call itself.
In the way of the HTML form submitted to see the output $srcpath;
Change it to the following way.

Thanks to "CodeIgniter China 1th" QQ Group of help, especially thanks, once very cow, Freda, I feed myself bag salt and other enthusiastic answer.

Multi-user album management, need to create album table, alias, album name, path one by one correspondence and so on.

This code here is only for a single user album operation, not applicable to multi-user album management.

See the landlord write code, when copying folders, is not only copied folders, folders inside the file will be copied but go to it? So I feel like I'm using recursion.

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

, I'm just a rookie, if there is a mistake, please advise.
