php完美的rss 生成类
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:
include_once ( "class/RSS.class.php" ); //引入RSS PHP类 $RSS = new RSS( "名称" , "地址" , "描述" , "RSS频道图标" ); $RSS ->AddItem( "日志的标题" , "日志的地址" , "日志的摘要" , "日志的发布日期" ); $RSS ->Display(); //输出RSS内容全部代码如下:
