rmdir手册中用户提供的部分包含一个体面的实现:

 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);
}
}

对于 * nix，可以对 rm -R使用 shell_exec，对 Windows 使用 DEL /S folder_name。

在 像素开发者的评论的基础上，使用 SPL 的代码片段可能类似于:

$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS),
RecursiveIteratorIterator::CHILD_FIRST
);


foreach ($files as $fileinfo) {
$todo = ($fileinfo->isDir() ? 'rmdir' : 'unlink');
$todo($fileinfo->getRealPath());
}


rmdir($dir);

注意: 它执行 没有健全性检查，并使用 PHP5.3.0中的 FilesystemIterator 引入的 SKIP _ DOTS 标志。当然，$todo可以是 if/else。重要的一点是，CHILD_FIRST用于首先遍历子文件(文件) ，然后遍历它们的父文件夹(文件夹)。

像这样吗？

function delete_folder($folder) {
$glob = glob($folder);
foreach ($glob as $g) {
if (!is_dir($g)) {
unlink($g);
} else {
delete_folder("$g/*");
rmdir($g);
}
}
}

“简单”的代码，一个十岁的孩子就能读懂:

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);
}
}

请注意，我所做的只是展开/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文件夹不是空的？

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/$file") && !is_link("$dir/$file")) ? recurseRmdir("$dir/$file") : unlink("$dir/$file");
}
return rmdir($dir);

这里还有另外一条线索，里面有更多的例子: PHP 的递归删除目录函数？

如果你正在使用 Yii，那么你可以把它留给框架:

CFileHelper::removeDirectory($my_directory);

我刚从 StackOverflow 的讨论中编写了这段代码。我还没有在 Linux 环境下进行测试。这样做是为了删除一个文件或目录，完全:

function splRm(SplFileInfo $i)
{
$path = $i->getRealPath();


if ($i->isDir()) {
echo 'D - ' . $path . '<br />';
rmdir($path);
} elseif($i->isFile()) {
echo 'F - ' . $path . '<br />';
unlink($path);
}
}


function splRrm(SplFileInfo $j)
{
$path = $j->getRealPath();


if ($j->isDir()) {
$rdi = new RecursiveDirectoryIterator($path, FilesystemIterator::SKIP_DOTS);
$rii = new RecursiveIteratorIterator($rdi, RecursiveIteratorIterator::CHILD_FIRST);
foreach ($rii as $i) {
splRm($i);
}
}
splRm($j);


}


splRrm(new SplFileInfo(__DIR__.'/../dirOrFileName'));

例如 Globa ()函数。它将递归删除所有文件和文件夹，包括以点开头的文件。

delete_all( 'folder' );


function delete_all( $item ) {
if ( is_dir( $item ) ) {
array_map( 'delete_all', array_diff( glob( "$item/{,.}*", GLOB_BRACE ), array( "$item/.", "$item/.." ) ) );
rmdir( $item );
} else {
unlink( $item );
}
};

@ XzaR 溶液的改良版。当所有文件都被删除时，它确实会删除空文件夹，并且会抛出异常，而不是在错误时返回 false。

function recursivelyRemoveDirectory($source, $removeOnlyChildren = true)
{
if (empty($source) || file_exists($source) === false) {
throw new Exception("File does not exist: '$source'");
}


if (is_file($source) || is_link($source)) {
if (false === unlink($source)) {
throw new Exception("Cannot delete file '$source'");
}
}


$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($source, RecursiveDirectoryIterator::SKIP_DOTS),
RecursiveIteratorIterator::CHILD_FIRST
);


foreach ($files as $fileInfo) {
/** @var SplFileInfo $fileInfo */
if ($fileInfo->isDir()) {
if ($this->recursivelyRemoveDirectory($fileInfo->getRealPath()) === false) {
throw new Exception("Failed to remove directory '{$fileInfo->getRealPath()}'");
}
if (false === rmdir($fileInfo->getRealPath())) {
throw new Exception("Failed to remove empty directory '{$fileInfo->getRealPath()}'");
}
} else {
if (unlink($fileInfo->getRealPath()) === false) {
throw new Exception("Failed to remove file '{$fileInfo->getRealPath()}'");

Unlinkr 函数通过确保不删除脚本本身，递归地删除给定路径中的所有文件夹和文件。

function unlinkr($dir, $pattern = "*") {
// find all files and folders matching pattern
$files = glob($dir . "/$pattern");


//interate thorugh the files and folders
foreach($files as $file){
//if it is a directory then re-call unlinkr function to delete files inside this directory
if (is_dir($file) and !in_array($file, array('..', '.')))  {
echo "<p>opening directory $file </p>";
unlinkr($file, $pattern);
//remove the directory itself
echo "<p> deleting directory $file </p>";
rmdir($file);
} else if(is_file($file) and ($file != __FILE__)) {
// make sure you don't delete the current script
echo "<p>deleting file $file </p>";
unlink($file);
}
}
}

如果要删除放置此脚本的所有文件和文件夹，请按以下方式调用该脚本

//get current working directory
$dir = getcwd();
unlinkr($dir);

如果你只是想删除 php 文件，然后调用如下

unlinkr($dir, "*.php");

您也可以使用任何其他路径来删除文件

unlinkr("/home/user/temp");

这将删除 home/user/temp 目录中的所有文件。

foreach(glob($dir . '/*') as $file) {

rrmdir($file);

或者这个。

<?php

$files = array_diff(scandir($dir), array('.','..'));
foreach ($files as $file) {
(is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file");

似乎所有其他的答案都假设给函数的路径总是一个目录。这个变体可以删除目录和单个文件:

/**
* Recursively delete a file or directory.  Use with care!
*
* @param string $path
*/
function recursiveRemove(string $path) {
if (is_dir($path)) {
foreach (scandir($path) as $entry) {
if (!in_array($entry, ['.', '..'], true)) {
recursiveRemove($path . DIRECTORY_SEPARATOR . $entry);
}
}
rmdir($path);
} else {
unlink($path);
}
}

编辑: 如果你很挑剔(你应该很挑剔) ，你可能想添加代码来检查 scandir()，rmdir()和 unlink()返回一个错误，如果是这样，抛出一个异常。

正确使用 DirectoryIterator 和递归:

function deleteFilesThenSelf($folder) {
foreach(new DirectoryIterator($folder) as $f) {
if($f->isDot()) continue; // skip . and ..
if ($f->isFile()) {
unlink($f->getPathname());
} else if($f->isDir()) {
deleteFilesThenSelf($f->getPathname());
}
}
rmdir($folder);
}
