I'm trying to use the PHP ZipArchive class, but I can't seem to get it to work.  It always has a status of 0, and the folder is never created.  The script is uploaded here.

PHP code:

---

    print("<pre>Result of file system search:\n\n");
    print_r(glob("{level,scenario}s/*/*.mf{l,s}", GLOB_BRACE));
    print("\nOpening archive...\n");
    $zip = new ZipArchive();
    $zip -> open("files.zip", ZIPARCHIVE::CREATE) or die("Error: could not open archive.");
    print("\nLoading levels through iterator...\n");
    $iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator("levels/"));
    foreach ($iterator as $key => $value)
    {
        print("| ".$key." => ".$value."\n");
        $zip -> addFile(realpath($key), $key) or die ("Error: could not add file: ".$key);
    }
    print("\nLoading scenarios through iterator...\n");
    $iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator("scenarios/"));
    foreach ($iterator as $key => $value)
    {
        print("| ".$key." => ".$value."\n");
        $zip -> addFile(realpath($key), $key) or die ("Error: could not add file: ".$key);
    }
    print("\nTotal number of files: ".$zip -> numFiles."\nArchive status: ".$zip -> status."</pre>");
    $zip -> close();

Di you need to add the folder structure manually? I have never worked with ZipArchive before...

I've tried using $zip->addEmptyDir() for the two directories and their subdirectories, but it doesn't make any difference.
