Thanks for your answers.

open($tmp_file, ZipArchive::CREATE);

    # loop through each file
    foreach($files as $file){

        # download file
        $download_file = file_get_contents($file);

        #add it to the zip
        $zip->addFromString(basename($file),$download_file);

    }

    # close zip
    $zip->close();

    # send the file to the browser as a download
    header('Content-disposition: attachment; filename=Resumes.zip');
    header('Content-type: application/zip');
    readfile($tmp_file);
 ?>
