我不记得从哪里复制了这个函数，但它看起来没有列出，它是为我工作

function rm_rf($path) {
    if (@is_dir($path) && is_writable($path)) {
        $dp = opendir($path);
        while ($ent = readdir($dp)) {
            if ($ent == '.' || $ent == '..') {
                continue;
            }
            $file = $path . DIRECTORY_SEPARATOR . $ent;
            if (@is_dir($file)) {
                rm_rf($file);
            } elseif (is_writable($file)) {
                unlink($file);
            } else {
                echo $file . "is not writable and cannot be removed. Please fix the permission or select a new path.\n";
            }
        }
        closedir($dp);
        return rmdir($path);
    } else {
        return @unlink($path);
    }
}

删除一个包含所有文件的目录最简单的方法是什么?

system("rm -rf ".escapeshellarg($dir));

现在至少有两种选择。

Before deleting the folder, delete all its files and folders (and this means recursion!). Here is an example: 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 implementing the recursion yourself: $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);

您可以复制YII帮助程序

$directory (string) -递归删除。

$options (array) -用于删除目录。 有效的选项是: traverseSymlinks:布尔值，是否也应该遍历指向目录的符号链接。默认为false，这意味着符号链接目录的内容不会被删除。在这种默认情况下，只会删除符号链接。

public static function removeDirectory($directory,$options=array())
{
    if(!isset($options['traverseSymlinks']))
        $options['traverseSymlinks']=false;
    $items=glob($directory.DIRECTORY_SEPARATOR.'{,.}*',GLOB_MARK | GLOB_BRACE);
    foreach($items as $item)
    {
        if(basename($item)=='.' || basename($item)=='..')
            continue;
        if(substr($item,-1)==DIRECTORY_SEPARATOR)
        {
            if(!$options['traverseSymlinks'] && is_link(rtrim($item,DIRECTORY_SEPARATOR)))
                unlink(rtrim($item,DIRECTORY_SEPARATOR));
            else
                self::removeDirectory($item,$options);
        }
        else
            unlink($item);
    }
    if(is_dir($directory=rtrim($directory,'\\/')))
    {
        if(is_link($directory))
            unlink($directory);
        else
            rmdir($directory);
    }
}

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);

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一下，以确保它能正常工作。

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.'"');

为了完整起见，这里是我的一个旧代码:

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);
}

类似Playnox的解决方案，但有优雅的内置DirectoryIterator:

function delete_directory($dirPath){
 if(is_dir($dirPath)){
  $objects=new DirectoryIterator($dirPath);
   foreach ($objects as $object){
    if(!$object->isDot()){
     if($object->isDir()){
      delete_directory($object->getPathname());
     }else{
      unlink($object->getPathname());
     }
    }
   }
   rmdir($dirPath);
  }else{
   throw new Exception(__FUNCTION__.'(dirPath): dirPath is not a directory!');
  }
 }
