problème ZIPLIB sur l'ouverture des fichiers zip

Question

J'utilise cette classe pour créer zip

<?php

     $timearray = ($unixtime == 0) ? getdate() : getdate($unixtime); 

     if ($timearray['year'] < 1980) { 
      $timearray['year'] = 1980;

Il crée un fichier zip, mais lorsque je tente de l'ouvrir sur Mac OS X Snow Leopard et Windows 7, il ne marche pas ouvert. sur mac j'ai eu cette erreur: Error 1: operation not permitted

Une idée?

grâce

EDIT: OK Je TROUVE UNE CLASSE DE TRAVAIL ICI

vous pouvez essayer cette classe http://www.phpclasses.org/package/2322-PHP-Create-ZIP-file-archives-and-serve-for-download.html (Avoir différentes classes pour Mac et PC)
