复制目录代码

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。

/**
     * [copyDir 复制文件夹]
     * @param  [type] $srcPath [来源目录]
     * @param  [type] $desPath [目的目录]
     * @return [type]          [description]
     */
    public function copyDir($srcPath=null,$desPath=null){
        /*$srcPath = isset($_POST['srcPath'])?$_POST['srcPath']:$srcPath;
        $desPath = isset($_POST['desPath'])?$_POST['desPath']:$desPath;*/
        if(!$srcPath && !$desPath){
            $srcPath = isset($_POST['srcPath'])?$_POST['srcPath']:null;
            $desPath = isset($_POST['desPath'])?$_POST['desPath']:null;
        }

        if(!$srcPath && !$desPath){
            exit;
        }

        $srcPath = $this->transChaset($srcPath,"GBK");
        $desPath = $this->transChaset($desPath,"GBK");
        if(!file_exists($desPath)){
            mkdir($desPath,0777,true);
        }
        if($handle = opendir($srcPath)){
            while (($item = readdir($handle)) !== false) {
                if($item!="."&&$item!=".."){
                    $item = $this->transChaset($item,"GBK");
                    if(is_file($srcPath."/".$item)){
                        $srcPathItem = $srcPath."/".$item;
                        $desPathItem = $desPath."/".$item;
                        copy($srcPathItem,$desPathItem);
                    }
                    if(is_dir($srcPath."/".$item)){

                        $this->copyDir($srcPathItem,$desPathItem);
                    }
                }
            }

            closedir($handle);
            $data = '复制文件夹成功';
            return json_encode(array("status"=>"OK", "data"=>$data));

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.
