代碼如下:

function rrmdir($dir) { 
if (is_dir($dir)) { 
$objects = scandir($dir); 
foreach ($objects as $object) { 
if ($object != “.” && $object != “..”) { 
if (filetype($dir.”/”.$object) == “dir”) rrmdir($dir.”/”.$object); else unlink($dir.”/”.$object); 
} 
} 
reset($objects); 
} 
} 

rmdir 
(PHP 4, PHP 5) 
rmdir — 刪除目錄 
Report a bug 說明 
bool rmdir ( string $dirname ) 
嘗試刪除 dirname 所指定的目錄。 該目錄必須是空的，而且要有相應的權限。成功時返回 TRUE， 或者在失敗時返回 FALSE. 
Note: 自 PHP 5.0.0 起 rmdir() 也可用于某些 URL 封裝協議。參見Supported Protocols and Wrappers 的列表看看 rmdir() 支持哪些 URL 封裝協議。 
Note: 在 PHP 5.0.0 中增加了 對上下文(Context)的支持。有關 上下文(Context) 的說明參見 Stream 函數。 
Note: 當啟用 安全模式時， PHP 會在執行腳本時檢查被腳本操作的目錄是否與被執行的腳本有相同的 UID（所有者）。 
參見 mkdir() 和 unlink()。 

復制代碼代碼如下:

<?php 
function rrmdir($dir) { 
if (is_dir($dir)) { 
$objects = scandir($dir); 
foreach ($objects as $object) { 
if ($object != "." && $object != "..") { 
if (filetype($dir."/".$object) == "dir") rrmdir($dir."/".$object); else unlink($dir."/".$object); 
} 
} 
reset($objects); 
rmdir($dir); 
} 
} 
?> 

This isn't my code, but just thought I would share, since it took me so long to find. This is a function to delete a folder, all sub-folders, and files in one clean move. 
Just tell it what directory you want deleted, in relation to the page that this function is executed. Then set $empty = true if you want the folder just emptied, but not deleted. If you set $empty = false, or just simply leave it out, the given directory will be deleted, as well. 

復制代碼代碼如下:

<?php 
function deleteAll($directory, $empty = false) { 
if(substr($directory,-1) == "/") { 
$directory = substr($directory,0,-1); 
} 
if(!file_exists($directory) || !is_dir($directory)) { 
return false; 
} elseif(!is_readable($directory)) { 
return false; 
} else { 
$directoryHandle = opendir($directory); 
while ($contents = readdir($directoryHandle)) { 
if($contents != '.' && $contents != '..') { 
$path = $directory . "/" . $contents; 
if(is_dir($path)) { 
deleteAll($path); 
} else { 
unlink($path); 
} 
} 
} 
closedir($directoryHandle); 
if($empty == false) { 
if(!rmdir($directory)) { 
return false; 
} 
} 
return true; 
} 
} 
?> 
[/code] 
A patch to previous script to make sure rights for deletion is set: 

復制代碼代碼如下:

<?php 
//Delete folder function 
function deleteDirectory($dir) { 
if (!file_exists($dir)) return true; 
if (!is_dir($dir) || is_link($dir)) return unlink($dir); 
foreach (scandir($dir) as $item) { 
if ($item == '.' || $item == '..') continue; 
if (!deleteDirectory($dir . "/" . $item)) { 
chmod($dir . "/" . $item, 0777); 
if (!deleteDirectory($dir . "/" . $item)) return false; 
}; 
} 
return rmdir($dir); 
} 
?>
