The user-contributed section in the manual page of rmdircontains a decent implementation:
手册页中的用户贡献部分rmdir包含一个不错的实现：
function rrmdir($dir) {
if (is_dir($dir)) {
$objects = scandir($dir);
foreach ($objects as $object) {
if ($object != "." && $object != "..") {
if (is_dir($dir. DIRECTORY_SEPARATOR .$object) && !is_link($dir."/".$object))
rrmdir($dir. DIRECTORY_SEPARATOR .$object);
else
unlink($dir. DIRECTORY_SEPARATOR .$object);
}
}
rmdir($dir);
}
}

Building on The Pixel Developer's comment, a snippet using the SPL might look like:
基于The Pixel Developer 的评论，使用 SPL 的片段可能如下所示：
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS),
RecursiveIteratorIterator::CHILD_FIRST
);
foreach ($files as $fileinfo) {
$todo = ($fileinfo->isDir() ? 'rmdir' : 'unlink');
$todo($fileinfo->getRealPath());
}
rmdir($dir);
Note: It does nosanity checking and makes use of the SKIP_DOTS flag introduced with the FilesystemIterator in PHP 5.3.0. Of course, the $todocould be an if/else. The important point is that CHILD_FIRSTis used to iterate over the children (files) first before their parent (folders).
注：它确实没有完整性检查，并利用在PHP 5.3.0与FilesystemIterator推出SKIP_DOTS标志。当然，$todo可以是if/ else。重要的一点是CHILD_FIRST用于在其父级（文件夹）之前首先迭代子级（文件）。

Deletes all files and folders in the path.
删除路径中的所有文件和文件夹。
function recurseRmdir($dir) {
$files = array_diff(scandir($dir), array('.','..'));
foreach ($files as $file) {
(is_dir("$dir/$file")) ? recurseRmdir("$dir/$file") : unlink("$dir/$file");
}
return rmdir($dir);
}

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：

'simple' code that works and can be read by a ten year old:
“简单”的代码可以工作并且可以被 10 岁的孩子阅读：
function deleteNonEmptyDir($dir)
{
if (is_dir($dir))
{
$objects = scandir($dir);
foreach ($objects as $object)
{
if ($object != "." && $object != "..")
{
if (filetype($dir . "/" . $object) == "dir")
{
deleteNonEmptyDir($dir . "/" . $object);
}
else
{
unlink($dir . "/" . $object);
}
}
}
reset($objects);
rmdir($dir);
}
}
Please note that all I did was expand/simplify and fix (didn't work for non empty dir) the solution here: In PHP how do I recursively remove all folders that aren't empty?
请注意，我所做的只是扩展/简化和修复（不适用于非空目录）这里的解决方案： 在 PHP 中，我如何递归删除所有非空文件夹？

Enhanced @Artefacto 's solution - corrected typos and simplified code, working for both - empty && non-empty directories .
增强了@Arteacto 的解决方案 - 更正了拼写错误并简化了代码，适用于两者 - 空 && 非空目录。
function recursive_rmdir($dir) {
if( is_dir($dir) ) {
$objects = array_diff( scandir($dir), array('..', '.') );
foreach ($objects as $object) {
$objectPath = $dir."/".$object;
if( is_dir($objectPath) )
recursive_rmdir($objectPath);
else
unlink($objectPath);
}
rmdir($dir);

It seems that all other answers assume the path given to the function is always a directory. This variant works to remove directories as well as single files:
似乎所有其他答案都假定给函数的路径始终是目录。此变体可用于删除目录和单个文件：
/**
* Recursively delete a file or directory. Use with care!
*
* @param string $path
*/
function recursiveRemove($path) {
if (is_dir($path)) {
foreach (scandir($path) as $entry) {
if (!in_array($entry, ['.', '..'])) {
recursiveRemove($path . DIRECTORY_SEPARATOR . $entry);
}
}
rmdir($path);
} else {
unlink($path);
}
}
