本文实例讲述了PHP生成RSS文件类文件。分享给大家供大家参考。具体如下：

PHP RSS 生成类实例代码如下:

复制代码 代码如下:<?php

if (defined('_class_rss_php')) return;

define('_class_rss_php教程',1);

/**

* 使用说明：

* $rss = new rss('redfox','http://jb51.net/',"redfox's blog");

* $rss->additem('rss class',"http://www.jb51.net","xxx",date());

* $rss->additem(...);

* $rss->savetofile(...);

*/
