How to add files to newly created folder in ziparchive using php?

问题

enter image description here

As in the image above ,I have images that are organized in virtual folders(in mysql database but not real folders). I need to make the selected folder available for download as zip .I was able to zip the images but how can we add subdirectory so as to add images to it (i tried using addEmptyDir() but couldn't figure out a way to add images into it! ). Is this really possible without creating the physical folder?

Please suggest!

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);
  }
}

If the "files" you want to add to your zip directory are stored in a db as strings, you could use ZipArchive::addFromString. If the db stores pointers to actual files use ZipArchive::addFile
