PHP はローカルサーバーの Web サイトとディレクトリにディレクトリを作成する必要がありますか?別のディスクに作成できないのでしょうか？

php只能在本地服务器网站跟目录创建目录吗？不能在其它盘创建吗？

<?php
    function copyDir($dirSrc,$dirTo){
        if(is_file($dirTo)){
            echo "目标不是目录不能创建";
            return ;
        }
        if(!file_exists($dirTo)){
            mkdir($dirTo);
        }
        
        if($dir_handle=@opendir($dirSrc)){
            while ($filename = readdir($dir_handle)){
                if($filename != "." && $filename != ".."){

                        copyDir($subSrcFile,$subToFile);
                    }
                    if(is_file($subSrcFile)){
                        copy($subSrcFile,$subToFile);
                    }
                }
            }
            closedir($dir_handle);
        }
    }
    copyDir("myphp","D:\\admin");
?>

把盘符去了，就可以创建。不知道为什么不到copy到其它盘
加盘符就会出现错误

------解决方案--------------------
你这个是各种错,路径不对,权限不对,自己检查清楚.
你是虚拟主机?
