[php] Creare zip sul server... non riesco a includere i files senza estenzione

[Trinità76]

Salve, premesso che ho seguito le istruzioni su questo thread:
http://forum.html.it/forum/showthrea...ostid=12215832
usando la libreria ic.zip.php (http://www.web-works.it/2008/08/zipp...rtella-in-php/)

Ho modificato il codice della libreria perchè generava alcuni warning in questo:
ic.zip.php

<?php
include("zip.lib.php");

ini_set("memory_limit","500M");

define("SZIP_DUMP",'dump');
define("SZIP_FILE",'file');
define("SZIP_SAVE",'save');

    var $zip;
    var $options;
    var $base_dir;

    function iczip($warn = true, $safe = true)
    {
        $this->zip = new zipfile;
        $this->options['warn'] = $warn;
        $this->options['safe'] = $safe;
    }
