rrmdir php中遞歸刪除目錄及目錄下的文件

更新時間：2011年05月15日 01:22:12 作者：

php自帶的rmdir，只能刪除空目錄，這個rrmdir就可以遞歸刪除目錄及目錄下的所有文件，不過使用起來要小心哦，不要把所有文件都刪了

 
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(yīng)的權(quán)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(xié)議。參見Supported Protocols and Wrappers 的列表看看 rmdir() 支持哪些 URL 封裝協(xié)議。
Note: 在 PHP 5.0.0 中增加了對上下文(Context)的支持。有關(guān) 上下文(Context) 的說明參見 Stream 函數(shù)。
Note: 當啟用安全模式時， PHP 會在執(zhí)行腳本時檢查被腳本操作的目錄是否與被執(zhí)行的腳本有相同的 UID（所有者）。
參見 mkdir() 和 unlink()。

復(fù)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(fù)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(fù)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); 
} 
?>
