$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);
    }
}

那么这个呢:

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);
}

如果你不确定，给定的路径是目录或文件，那么你可以使用这个函数删除路径

function deletePath($path) {
        if(is_file($path)){
            unlink($path);
        } elseif(is_dir($path)){
            $path = (substr($path, -1) !== DIRECTORY_SEPARATOR) ? $path . DIRECTORY_SEPARATOR : $path;
            $files = glob($path . '*');
            foreach ($files as $file) {
                deleteDirPath($file);
            }
            rmdir($path);
        } else {
            return false;
        }
}

<?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

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);
}

以Linux服务器为例:exec('rm -f -r '。cache_folder美元。“/ *”);
