A recursive remove directory function for PHP?
提问by rhodesjason
I am using PHP to move the contents of a images subfolder
我正在使用 PHP 移动图像子文件夹的内容
GalleryName/images/
画廊名称/图片/
into another folder. After the move, I need to delete the GalleryName directory and everything else inside it.
到另一个文件夹。移动后，我需要删除 GalleryName 目录和其中的所有其他内容。
I know that rmdir()won't work unless the directory is empty. I've spent a while trying to build a recursive function to scandir()starting from the top and then unlink()if it's a file and scandir()if it's a directory, then rmdir()each empty directory as I go.
我知道rmdir()除非目录为空，否则这将不起作用。我花了一段时间试图构建一个递归函数，scandir()从顶部开始，然后unlink()如果它是一个文件，scandir()如果它是一个目录，那么rmdir()我去每个空目录。
So far it's not working exactly right, and I began to think -- isn't this a ridiculously simple function that PHP should be able to do?Removing a directory?
到目前为止，它的工作并不完全正确，我开始思考——这难道不是 PHP 应该能够做到的一个非常简单的函数吗？删除目录？
So is there something I'm missing? Or is there at least a proven function that people use for this action?
那么有什么我想念的吗？或者至少有一个经过验证的功能可供人们用于此操作？
Any help would be appreciated.
任何帮助，将不胜感激。
PS I trust you all here more than the comments on the php.net site -- there are hundreds of functions there but I am interested to hear if any of you here recommend one over others.
PS 我比 php.net 站点上的评论更相信你们所有人——那里有数百个功能，但我很想听听你们中是否有人推荐一个而不是其他功能。

What about this?
那这个呢？
foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dirPath, FilesystemIterator::SKIP_DOTS), RecursiveIteratorIterator::CHILD_FIRST) as $path) {
$path->isDir() && !$path->isLink() ? rmdir($path->getPathname()) : unlink($path->getPathname());
}
rmdir($dirPath);

This is the recursive function I've created/modifed and that finally seems to be working. Hopefully there isn't anything too dangerous in it.
这是我创建/修改的递归函数，它最终似乎起作用了。希望里面没有什么太危险的东西。
function destroy_dir($dir) {
if (!is_dir($dir) || is_link($dir)) return unlink($dir);
foreach (scandir($dir) as $file) {
if ($file == '.' || $file == '..') continue;
if (!destroy_dir($dir . DIRECTORY_SEPARATOR . $file)) {
chmod($dir . DIRECTORY_SEPARATOR . $file, 0777);
if (!destroy_dir($dir . DIRECTORY_SEPARATOR . $file)) return false;
};
}
return rmdir($dir);
}

If the server of application runs linux, just use the shell_exec() function, and provide it the rm -R command, like this:
如果应用程序的服务器运行的是 linux，只需使用 shell_exec() 函数，并为其提供 rm -R 命令，如下所示：
$realPath = realpath($dir_path);
if($realPath === FALSE){
throw new \Exception('Directory does not exist');
}
shell_exec("rm ". escapeshellarg($realPath) ." -R");
Explanation:
解释：
Removes the specified directory recursively only if the path exists and escapes the path so that it can only be used as a shell argument to avoid shell command injection.
仅当路径存在时递归删除指定目录并转义路径，使其只能用作 shell 参数以避免 shell 命令注入。
If you wouldnt use escapeshellargone could execute commands by naming the directory to be removed after a command.
如果您不使用，escapeshellarg则可以通过在命令后命名要删除的目录来执行命令。

There is another thread with more examples here: How do I recursively delete a directory and its entire contents (files + sub dirs) in PHP?
这里还有另一个包含更多示例的线程： How do I recursively delete a directory and its entire contents (files + sub dirs) in PHP?
If you are using Yii then you can leave it to the framework:
如果你使用 Yii，那么你可以把它留给框架：
CFileHelper::removeDirectory($my_directory);

I prefer an enhaced method derived from the php help pages http://php.net/manual/en/function.rmdir.php#115598
我更喜欢从 php 帮助页面http://php.net/manual/en/function.rmdir.php#115598派生的增强方法
// check accidential empty, root or relative pathes
if (!empty($path) && ...)
{
if (PHP_OS === 'Windows')
{
exec('rd /s /q "'.$path.'"');
}
else
{
exec('rm -rf "'.$path.'"');
}
}
else
{
error_log('path not valid:$path'.var_export($path, true));
}
reasons for my decision:
我的决定的原因：
- less code
- speed
- keep it simple
- 更少的代码
- 速度
- 把事情简单化

$files = scandir($dir);
foreach ($files as $file) {

else

I've adapted a function which handles hidden unix files with the dot prefix and uses glob:
我改编了一个函数，它处理带有点前缀的隐藏 unix 文件并使用 glob：
public static function deleteDir($path) {
if (!is_dir($path)) {
throw new InvalidArgumentException("$path is not a directory");
}
if (substr($path, strlen($path) - 1, 1) != '/') {
$path .= '/';
}
$dotfiles = glob($path . '.*', GLOB_MARK);
$files = glob($path . '*', GLOB_MARK);
$files = array_merge($files, $dotfiles);
foreach ($files as $file) {
if (basename($file) == '.' || basename($file) == '..') {
continue;
} else if (is_dir($file)) {
self::deleteDir($file);
} else {
unlink($file);
}
}
rmdir($path);
}
