Since you just need specific files from a directory to create ZipArchive you can use glob() function to do this.

open($download, ZipArchive::CREATE);
    foreach (glob("images/*.png") as $file) { /* Add appropriate path to read content of zip */
        $zip->addFile($file);
    }
    $zip->close();
    header('Content-Type: application/zip');
    header("Content-Disposition: attachment; filename = $download");
    header('Content-Length: ' . filesize($download));
    header("Location: $download");
 ?>

Don't use glob() if you try to list files in a directory where very much files are stored (more than 100.000). You get an "Allowed memory size of XYZ bytes exhausted ..." error.

readdir() is more stable way.
