删除目录中有文件吗?

I wonder, what's the easiest way to delete a directory with all its files in it?

我想知道，删除包含所有文件的目录最简单的方法是什么?

I'm using rmdir(PATH . '/' . $value); to delete a folder, however, if there are files inside of it, I simply can't delete it.

我用删除路径(路径。“/”。美元价值);但是，要删除一个文件夹，如果里面有文件，我就不能删除它。

There are at least two options available nowdays.

现在至少有两个选择。

Before deleting the folder, delete all it's files and folders (and this means recursion!). Here is an example:

在删除文件夹之前，删除它的所有文件和文件夹(这意味着递归!)这是一个例子:

public static function deleteDir($dirPath) {
    if (! is_dir($dirPath)) {
        throw new InvalidArgumentException("$dirPath must be a directory");
    }
    if (substr($dirPath, strlen($dirPath) - 1, 1) != '/') {
        $dirPath .= '/';
    }
    $files = glob($dirPath . '*', GLOB_MARK);
    foreach ($files as $file) {
        if (is_dir($file)) {
            self::deleteDir($file);
        } else {
            unlink($file);
        }
    }
    rmdir($dirPath);
}

And if you are using 5.2+ you can use a RecursiveIterator to do it without needing to do the recursion yourself:

如果您正在使用5.2+，您可以使用一个RecursiveIterator来实现它，而不需要自己进行递归:

$dir = 'samples' . DIRECTORY_SEPARATOR . 'sampledirtree';
$it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($it,
             RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $file) {
    if ($file->isDir()){
        rmdir($file->getRealPath());
    } else {
        unlink($file->getRealPath());
    }
}
rmdir($dir);

I generally use this to delete all files in a folder:

我通常用它来删除文件夹中的所有文件:

array_map('unlink', glob("$dirname/*.*"));

And then you can do

然后你可以这么做

rmdir($dirname);

Short function that does the job:

完成工作的短功能:

function deleteDir($path) {
    return is_file($path) ?
            @unlink($path) :
            array_map(__FUNCTION__, glob($path.'/*')) == @rmdir($path);
}

I use it in a Utils class like this:

我在Utils类中使用如下:

class Utils {
    public static function deleteDir($path) {
        $class_func = array(__CLASS__, __FUNCTION__);
        return is_file($path) ?
                @unlink($path) :
                array_map($class_func, glob($path.'/*')) == @rmdir($path);
    }
}

With great power comes great responsibility: When you call this function with an empty value, it will delete files starting in root (/). As a safeguard you can check if path is empty:

强大的功能带来了巨大的责任:当你用空值调用这个函数时，它会删除从root(/)开始的文件。作为保障，你可以检查路径是否为空:

function deleteDir($path) {
    if (empty($path)) { 
        return false;
    }
    return is_file($path) ?
            @unlink($path) :
            array_map(__FUNCTION__, glob($path.'/*')) == @rmdir($path);
}

#5

This is a shorter Version works great to me

这个较短的版本对我来说很好

function deleteDirectory($dirPath) {
    if (is_dir($dirPath)) {
        $objects = scandir($dirPath);
        foreach ($objects as $object) {
            if ($object != "." && $object !="..") {
                if (filetype($dirPath . DIRECTORY_SEPARATOR . $object) == "dir") {
                    deleteDirectory($dirPath . DIRECTORY_SEPARATOR . $object);
                } else {
                    unlink($dirPath . DIRECTORY_SEPARATOR . $object);
                }
            }
        }
    reset($objects);
    rmdir($dirPath);
    }
}

As seen in most voted comment on PHP manual page about rmdir() (see http://php.net/manual/es/function.rmdir.php), glob() function does not return hidden files. scandir() is provided as an alternative that solves that issue.

在关于rmdir()的PHP手册页面(请参见http://php.net/manual/es/function.rmdir.php)上的大多数投票评论中可以看到，glob()函数不返回隐藏文件。提供scandir()作为解决该问题的备选方案。

Algorithm described there (which worked like a charm in my case) is:

这里描述的算法(在我的例子中就像魔法一样)是:

<?php 
    function delTree($dir)
    { 
        $files = array_diff(scandir($dir), array('.', '..')); 

        foreach ($files as $file) { 
            (is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file"); 
        }

        return rmdir($dir); 
    } 
?>

Here you have one nice and simple recursion for deleting all files in source directory including that directory:

这里有一个简单的递归，用于删除源目录中的所有文件，包括该目录:

function delete_dir($src) { 
    $dir = opendir($src);
    while(false !== ( $file = readdir($dir)) ) { 
        if (( $file != '.' ) && ( $file != '..' )) { 
            if ( is_dir($src . '/' . $file) ) { 
                delete_dir($src . '/' . $file); 
            } 
            else { 
                unlink($src . '/' . $file); 
            } 
        } 
    } 
    closedir($dir); 
    rmdir($src);

}

Function is based on recursion made for copying directory. You can find that function here: Copy entire contents of a directory to another using php

函数基于复制目录的递归。您可以在这里找到这个函数:使用php将目录的整个内容复制到另一个目录

You may use Symfony's Filesystem (code):

您可以使用Symfony的文件系统(代码):

// composer require symfony/filesystem

use Symfony\Component\Filesystem\Filesystem;

(new Filesystem)->remove($dir);

However I couldn't delete some complex directory structures with this method, so first you should try it to ensure it's working properly.

但是我不能用这个方法删除一些复杂的目录结构，所以首先您应该尝试它以确保它正常工作。

I could delete the said directory structure using a Windows specific implementation:

我可以使用Windows特定的实现删除上述目录结构:

$dir = strtr($dir, '/', '\\');
// quotes are important, otherwise one could
// delete "foo" instead of "foo bar"
system('RMDIR /S /Q "'.$dir.'"');

And just for the sake of completeness, here is an old code of mine:

为了完整性起见，这里有一个我的旧代码:

function xrmdir($dir) {
    $items = scandir($dir);
    foreach ($items as $item) {
        if ($item === '.' || $item === '..') {
            continue;
        }
        $path = $dir.'/'.$item;
        if (is_dir($path)) {
            xrmdir($path);
        } else {
            unlink($path);
        }
    }
    rmdir($dir);
}

I prefer this because it still returns TRUE when it succeeds and FALSE when it fails, and it also prevents a bug where an empty path might try and delete everything from '/*' !!:

我更喜欢这个，因为当它成功时它仍然返回TRUE，当它失败时它返回FALSE，并且它还可以防止一个空路径试图从'/*'中删除所有内容的错误!

function deleteDir($path)
{
    return !empty($path) && is_file($path) ?
        @unlink($path) :
        (array_reduce(glob($path.'/*'), function ($r, $i) { return $r && deleteDir($i); }, TRUE)) && @rmdir($path);
}

#10

What about this:

这个:

function recursiveDelete($dirPath, $deleteParent = true){
    foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dirPath, FilesystemIterator::SKIP_DOTS), RecursiveIteratorIterator::CHILD_FIRST) as $path) {
        $path->isFile() ? unlink($path->getPathname()) : rmdir($path->getPathname());
    }
    if($deleteParent) rmdir($dirPath);
}

#11

Glob function doesn't return the hidden files, therefore scandir can be more useful, when trying to delete recursively a tree.

Glob函数不返回隐藏的文件，因此当尝试递归地删除树时，scandir可能更有用。

<?php
public static function delTree($dir) {
   $files = array_diff(scandir($dir), array('.','..'));
    foreach ($files as $file) {
      (is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file");
    }
    return rmdir($dir);
  }
?>

Litle bit modify of alcuadrado's code - glob don't see files with name from points like .htaccess so I use scandir and script deletes itself - check __FILE__.

Litle bit修改了alcuadrado的代码——glob不从点(比如.htaccess)看到文件名的文件，所以我使用scandir并删除脚本——检查__FILE__。

function deleteDir($dirPath) {
    if (!is_dir($dirPath)) {
        throw new InvalidArgumentException("$dirPath must be a directory");
    }
    if (substr($dirPath, strlen($dirPath) - 1, 1) != '/') {
        $dirPath .= '/';
    }
    $files = scandir($dirPath); 
    foreach ($files as $file) {
        if ($file === '.' || $file === '..') continue;
        if (is_dir($dirPath.$file)) {
            deleteDir($dirPath.$file);
        } else {
            if ($dirPath.$file !== __FILE__) {
                unlink($dirPath.$file);
            }
        }
    }
    rmdir($dirPath);
}

#13

The Best Solution for me

对我来说最好的解决办法

my_folder_delete("../path/folder");

code:

代码:

function my_folder_delete($path) {
    if(!empty($path) && is_dir($path) ){
        $dir  = new RecursiveDirectoryIterator($path, RecursiveDirectoryIterator::SKIP_DOTS); //upper dirs are not included,otherwise DISASTER HAPPENS :)
        $files = new RecursiveIteratorIterator($dir, RecursiveIteratorIterator::CHILD_FIRST);
        foreach ($files as $f) {if (is_file($f)) {unlink($f);} else {$empty_dirs[] = $f;} } if (!empty($empty_dirs)) {foreach ($empty_dirs as $eachDir) {rmdir($eachDir);}} rmdir($path);
    }
}

p.s. REMEMBER!
dont pass EMPTY VALUES to any Directory deleting functions!!! (backup them always, otherwise one day you might get DISASTER!!)

注。记住!不要将空值传递给任何删除函数的目录!!(随时备份，否则有一天你可能会遭遇灾难!)

I want to expand on the answer by @alcuadrado with the comment by @Vijit for handling symlinks. Firstly, use getRealPath(). But then, if you have any symlinks that are folders it will fail as it will try and call rmdir on a link - so you need an extra check.

我想扩展@alcuadrado的答案，使用@Vijit处理符号链接的注释。首先,使用getRealPath()。但是，如果您有任何作为文件夹的符号链接，它将失败，因为它将尝试在一个链接上调用rmdir——因此您需要额外的检查。

$it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($it, RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $file) {
    if ($file->isLink()) {
        unlink($file->getPathname());
    } else if ($file->isDir()){
        rmdir($file->getPathname());
    } else {
        unlink($file->getPathname());
    }
}
rmdir($dir);

#15

Something like this?

是这样的吗?

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

Delete all files in Folder
array_map('unlink', glob("$directory/*.*"));
Delete all .*-Files in Folder (without: "." and "..")
array_map('unlink', array_diff(glob("$directory/.*),array("$directory/.","$directory/..")))
Now delete the Folder itself
rmdir($directory)

删除文件夹array_map中的所有文件(“unlink”，glob(“$directory/*.*”));删除文件夹中的所有.*-文件(没有:"."和".")array_map('unlink'， array_diff($directory/.*)，数组("$directory/."，"$directory/. ")))

2 cents to add to THIS answer above, which is great BTW

在上面的答案上再加2分，这很好

After your glob (or similar) function has scanned/read the directory, add a conditional to check the response is not empty, or an invalid argument supplied for foreach() warning will be thrown. So...

在您的glob(或类似的)函数扫描/读取目录之后，添加一个条件来检查响应不是空的，或者为foreach()警告提供的无效参数将被抛出。所以…

if( ! empty( $files ) )
{
    foreach( $files as $file )
    {
        // do your stuff here...
    }
}

        }

        if( substr( $directory, strlen( $directory ) - 1, 1 ) != '/' )
        {
            $directory .= '/';

        if ($fileToDelete->isFile())
            unlink($fileToDelete->getPathName());
