看了半天，原來是自己在函數開始的地方isset寫了一個死迴圈，函數不停的在調用自身。
用html表單提交的方式看到不停的在輸出$srcPath;
改成下面這種方式就可以了。

感謝 【CodeIgniter 中國1號】QQ群的協助， 尤其感謝，曾經很牛，freda，我喂自己袋鹽等的熱心解答。

多使用者的相簿管理，需要建立相簿表，別名，相簿名，路徑一一對應等。

這裡的這個代碼只是針對單一使用者的相簿操作，並不適用多使用者相簿管理。

看到樓主寫的代碼，當複製檔案夾的時候，是不是只會複製檔案夾，檔案夾裡面的檔案會複製不過去呢?所以我感覺那點用上遞迴

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

,我只是個菜鳥，如有錯誤，請指教.
