From the first comment in the official documentation.
来自官方文档中的第一条评论。
<?php
// When the directory is not empty:
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);
}
}
?>
Edited rmdir to rrmdir to correct typo from obvious intent to create recursive function.
将 rmdir 编辑为 rrmdir 以纠正明显意图创建递归函数的拼写错误。

Something like this should do it...
这样的事情应该这样做......
function removeDir($path) {
// Normalise $path.
$path = rtrim($path, '/') . '/';
// Remove all child files and directories.
$items = glob($path . '*');
foreach($items as $item) {
is_dir($item) ? removeDir($item) : unlink($item);
}
// Remove directory.
rmdir($path);
}
removeDir('/path/to/dir');
This deletes all child files and folders and then removes the top level folder passed to it.
这将删除所有子文件和文件夹，然后删除传递给它的顶级文件夹。
It could do with some error checking such as testing the path supplied is a directory and making sure each deletion was successful.
它可以进行一些错误检查，例如测试提供的路径是一个目录并确保每次删除都成功。

To recursively delete a directory use this:
要递归删除目录，请使用以下命令：
function rrmdir($path) {
return is_file($path)? @unlink($path): array_map(__NAMESPACE__ . '\rrmdir',glob($path.'/*'))==@rmdir($path);
}
Only tested on unix.
