RSS订阅制作

在网上找了一篇RSS制作的文章，觉得挺有用。先申明没测试过。

RSS.PHP代码:

<?php
/**

if (defined('_CLASS_RSS_PHP')) return;
define('_CLASS_RSS_PHP',1);

class RSS {

var $webMaster = '';
var $pubDate = '';
var $lastBuildDate = '';
var $generator = 'RedFox RSS Generator';

var $content = '';
var $items = array();

/**************************************************************************/
