[求教代码]google的xml格式的sitemap的PHP生成代码

[gongyi101459]

google的xml格式的sitemap的PHP生成代码，能生成网站根目录下的所有链接的文件啊
其实在线生成的有很多，例如：http://www.xml-sitemaps.com/
但我想在网站上安装个这样的插件，望高手指点！
补充：PE的有这样的，但是asp的

[gongyi101459]

google新推出的sitemap，是对原来robots.txt的扩展，sitemap!使用xml格式来记录整个网站的信息并供google读取，使搜索引擎能更快更全面的收录网站的内容。

sitemap的作用就好像为网站提供了整站的rss，而google就是这些rss的订阅者，只要网站有更新就会自动通知google。这样一来，搜索引擎的收录由被动的pull变成了主动的push，辛苦的google爬虫们终于可以松一口气了。
