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); 
   } 
 }

基于The Pixel Developer's comment，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);

注意：它不进行完整性检查，并使用 PHP 5.3.0 中的 FilesystemIterator 引入的 SKIP_DOTS 标志。当然，$todo可能是if/ else。重要的一点是CHILD_FIRST用于在其父级（文件夹）之前先遍历子级（文件）。

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);
}

对于 *nix，您可以使用shell_execforrm -R或DEL /S folder_namefor Windows。

这里还有另一个带有更多示例的线程： A recursive remove directory function for PHP?

如果您使用的是 Yii，那么您可以将其留给框架：

CFileHelper::removeDirectory($my_directory);

似乎所有其他答案都假设给函数的路径总是一个目录。此变体可用于删除目录以及单个文件：

/**
 * 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），你可能想要添加代码来检查scandir()，如果是rmdir()，unlink()则返回错误并抛出异常。

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);
}

glob()函数的示例。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 );
    }
};

“简单”的代码可以工作并且可以被十岁的孩子阅读：

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);

unlinkr 函数通过确保它不会删除脚本本身来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，请按以下方式调用它

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

如果您只想删除 php 文件，请按以下方式调用它

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。
