       $path = public_path('word');

        $zip = new \ZipArchive;
        $zip->open($zipFileName, \ZipArchive::CREATE | \ZipArchive::OVERWRITE); 
        $files = new \RecursiveIteratorIterator(new \RecursiveDirectoryIterator($path));
        foreach ($files as $name =>$file)
        {
         if (!$file->isDir()) {
          $filePath  = $file->getRealPath();
          $relativePath = 'word/' . substr($filePath, strlen($path) + 1);
          $zip->addFile($filePath, $relativePath);
         } 
        }
        
        $file_name = mb_convert_encoding($zipFileName,'GB2312','UTF-8');
        header('Content-type: application/zip');
        header("Content-Disposition: attachment; filename=\"{$file_name}\"");
        readfile(public_path($file_name));
        unlink(public_path($file_name));
