PHP生成RSS文件类实例

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:

<?php 

if (defined('_class_rss_php')) return; 

define('_class_rss_php教程',1); 

/** 

 

 *  使用说明： 

 *  $rss = new rss('redfox','http://3water.com/',"redfox's blog"); 

 *  $rss->additem('rss class',"https://3water.com","xxx",date()); 

 *  $rss->additem(...); 

 *  $rss->savetofile(...);
