TP download folder, compress folder and download

/** *  Encapsulate compressed files  * @param $name */
public function zipFile($name){
    
    $zip = new \ZipArchive();
    
	//  The file needs to be compressed 
    $file_name = ROOT_PATH.'public'.DS.'uploads'.DS.$name;

        } else {
    
            throw new NotFoundHttpException(' The directory does not exist or has been deleted ');
        }
    }

    // pack zip
    $zip->close();
}

encapsulation zip class , It can also be used as a method

class Zip extends Controller
{
    
    public static function addFileToZip($path, &$zip,$root='')
    {
    
        $handler = opendir($path); // Open the current folder by $path Appoint .
        !$root && $root = $path;

        while (($filename = readdir($handler)) !== false)
        {
    
            if ($filename != "." && $filename != "..")
            {
    // The folder file name is '.' and ‘..’, Don't operate on them 
                if (is_dir($path . "/" . $filename))
                {
    //  If an object read is a folder , Then recursion 
                    self::addFileToZip($path . "/" . $filename, $zip, $root);
                }
                else
                {
     // Add files to zip object 
                    $pathFilename=$path . "/" . $filename;
                    $zip->addFile($pathFilename, str_replace($root.'/','',$pathFilename));
                }
            }
        }
        @closedir($path);
    }

}
