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);
}

对我来说最好的解决方案

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

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);
    }
}

注。记住!不要将空值传递给任何目录删除函数!!(总是备份它们，否则有一天你可能会遇到灾难!!)

这里有一个完美的解决方案:

function unlink_r($from) {
    if (!file_exists($from)) {return false;}
    $dir = opendir($from);
    while (false !== ($file = readdir($dir))) {
        if ($file == '.' OR $file == '..') {continue;}

        if (is_dir($from . DIRECTORY_SEPARATOR . $file)) {
            unlink_r($from . DIRECTORY_SEPARATOR . $file);
        }
        else {
            unlink($from . DIRECTORY_SEPARATOR . $file);
        }
    }
    rmdir($from);
    closedir($dir);
    return true;
}

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);

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;
        }
}

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!');
  }
 }
