发布:smiling 来源: PHP粉丝网  添加日期:2014-08-29 13:54:34 浏览: 评论:0 

RSS订阅功能,在很多网站都可以有但也有很多,下面代码是自己写的,其中使用到了一个PHP类:RSS.class.php,感觉非常方便,不敢独享,特拿出来跟大家分享.

类的调用代码如下:

  1. include_once("class/RSS.class.php");//引入RSS PHP类 
  2. $RSSnew RSS("名称","地址","描述","RSS频道图标"); 
  3. $RSS->AddItem("日志的标题","日志的地址","日志的摘要","日志的发布日期"); 
  4. $RSS->Display();//输出RSS内容 

全部代码如下:
