这篇文章主要介绍了PHP生成RSS文件类,可实现PHP生成RSS文件的功能,对于网站建设与优化来说具有一定的实用价值,需要的朋友可以参考下

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:

1. <?php
2. if (defined('_class_rss_php')) return;
3. define('_class_rss_php粉丝网',1);
4. /**
5. * 使用说明：
6. * $rss = new rss('redfox','http://phpfensi.com/',"redfox's blog");
7. * $rss->additem('rss class',"https://www.phpfensi.com","xxx",date());
8. * $rss->additem(...);
9. * $rss->savetofile(...);
10. */
