Answer 1

Thanks @dnagirl for your answer, but I was actually looking for a way to add files inside subfolders (maybe I was unable to make myself clear!)

discovered that zipArchive automatically creates folder if we give 'path/to/filename' instead of just 'filename'

This is how I achieved it in case anybody may need it!

function zipFilesAndDownload($file_names,$archive_file_name,$img_localpath)
{
  $folder_path=WSP_AK_PLUGIN_DIR ."akTempFolder/";
  $zip = new ZipArchive();
  if ($zip->open($folder_path.$archive_file_name, ZIPARCHIVE::CREATE )===TRUE) {
    //$zip->addEmptyDir('myimages');(this was what i thought would create folder!)
    foreach($file_names as $files)
    {
        //$zip->addFile($img_localpath.'/'.$files, 'myfolder/'.$files);
        $zip->addFile($img_localpath.'/'.$files['fileName'],    $files['folder_path'].$files['fileName']);
    }
    $zip->close();

in above code $files['folder_path'] will give the path to file where it will be created For eg folder1/folder2/image1.jpg

    header("Content-type: application/zip"); 
    header("Content-Disposition: attachment; filename=$archive_file_name");
    header('Content-Type: application/force-download');
    header('Content-Length: ' . filesize($folder_path.$archive_file_name));
    header("Pragma: no-cache"); 
    header("Expires: 0");
    if( file_exists($folder_path.$archive_file_name)) {
        ob_clean();
        readfile($folder_path.$archive_file_name);
    }
    unlink($folder_path.$archive_file_name);
  }
}
