Remove all files, folders and their subfolders with php
提问by donald123
I need a script which can remove a whole directory with all their subfolders, files and etc. I tried with this function which I found in internet before few months ago but it not work completely.
我需要一个脚本，它可以删除整个目录及其所有子文件夹、文件等。我尝试过几个月前在互联网上找到的这个功能，但它不能完全工作。
function deleteFile($dir) {
if(substr($dir, strlen($dir)-1, 1) != '/') {
$dir .= '/';
}
if($handle = opendir($dir)) {
while($obj = readdir($handle)) {
if($obj != '.' && $obj != '..') {
if(is_dir($dir.$obj)) {
if(!deleteFile($dir.$obj)) {
echo $dir.$obj."<br />";
return false;
}
}
elseif(is_file($dir.$obj)) {
if(!unlink($dir.$obj)) {
echo $dir.$obj."<br />";
return false;
}
}
}
}
closedir($handle);
if(!@rmdir($dir)) {
echo $dir.'<br />';
return false;
}
return true;
}
return true;
}
For the test I use a unpacked archive of prestashop and I try to delete the folder where archive is unpacked but it doesn't work.
对于测试，我使用了 prestashop 的解压存档，我尝试删除解压存档的文件夹，但它不起作用。
/home/***/public_html/prestashop/img/p/3/
/home/***/public_html/prestashop/img/p/3
/home/***/public_html/prestashop/img/p
/home/***/public_html/prestashop/img
These are the problem folders. At the first time I think - "May is a problem with the chmod of the files" but when I test with all files chmod permission 755 (after that with 777) - the result was the same.
这些是问题文件夹。我第一次想 - “可能是文件的 chmod 有问题”但是当我使用 chmod 权限 755（之后是 777）测试所有文件时 - 结果是一样的。

<?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);
}
}
?>
Try out the above code from php.net
从php.net尝试上面的代码
Worked fine for me
对我来说很好用

You can use a cleaner method for doing a recursive delete of a directory.
您可以使用更清洁的方法对目录进行递归删除。
Example:
例子：
function recursiveRemove($dir) {
$structure = glob(rtrim($dir, "/").'/*');
if (is_array($structure)) {
foreach($structure as $file) {
if (is_dir($file)) recursiveRemove($file);
elseif (is_file($file)) unlink($file);
}
}
rmdir($dir);
}
Usage:
用法：
recursiveRemove("test/dir/");
