$dir = new RecursiveDirectoryIterator(__DIR__,RecursiveDirectoryIterator::SKIP_DOTS);

$address = new RecursiveIteratorIterator(new TmPRecursiveFilterIterator($dir),RecursiveIteratorIterator::CATCH_GET_CHILD);


foreach($address as $dir) {
    echo $dir,PHP_EOL;
}

使用的类

class TmpRecursiveFilterIterator extends RecursiveFilterIterator {
    public function accept() {
        $file = $this->current();
        if ($file->isDir()) {
            return is_dir("$file/tmp");
        }
        return false;
    }
}
