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 code

<?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($dirTo);        }                if([email protected]($dirSrc)){            while ($filename = readdir($dir_handle)){                if($filename != "." && $filename != ".."){                    $subSrcFile = $dirSrc."\\".$filename;                    $subToFile = $dirTo."\\".$filename;                                        if(is_dir($subSrcFile)){                        copyDir($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?
