使用DirectoryIterator等价于之前的答案…

function deleteFolder($rootPath)
{   
    foreach(new DirectoryIterator($rootPath) as $fileToDelete)
    {
        if($fileToDelete->isDot()) continue;
        if ($fileToDelete->isFile())
            unlink($fileToDelete->getPathName());
        if ($fileToDelete->isDir())
            deleteFolder($fileToDelete->getPathName());
    }

    rmdir($rootPath);
}

简单易行…

$dir ='pathtodir';
if (is_dir($dir)) {
  foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename) {
    if ($filename->isDir()) continue;
    unlink($filename);
  }
  rmdir($dir);
}

<?php
  function rrmdir($dir) {
  if (is_dir($dir)) {
    $objects = scandir($dir);
    foreach ($objects as $object) {
      if ($object != "." && $object != "..") {
        if (filetype($dir."/".$object) == "dir") 
           rrmdir($dir."/".$object); 
        else unlink   ($dir."/".$object);
      }
    }
    reset($objects);
    rmdir($dir);
  }
 }
?>

你试过上述代码从php.net吗

为我工作吧

这是一个更短的版本，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);
    }
}

使用DirectoryIterator等价于之前的答案…

{   
    foreach(new DirectoryIterator($rootPath) as $fileToDelete)
    {
        if($fileToDelete->isDot()) continue;
        if ($fileToDelete->isFile())
            unlink($fileToDelete->getPathName());
        if ($fileToDelete->isDir())
            deleteFolder($fileToDelete->getPathName());
    }

    rmdir($rootPath);
}

我更喜欢这个，因为它仍然在成功时返回TRUE，失败时返回FALSE，而且它还防止了一个错误，即一个空路径可能会尝试删除'/*'中的所有内容!!：

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);
}
