PHPBB的sitemap制作，生成有利于SEO的网址_php 动态显示 sitemap-优快云博客

本文提供了一个用于生成PHPBB论坛站点地图的PHP脚本。通过调整脚本中的变量，可以将其应用于不同域名和路径的论坛上。该脚本能够自动生成符合Sitemap标准的XML文件，便于搜索引擎抓取。

将以下PHP文件放到你网站的根目录就OK了。

加入此sitemap的前提是，必须将PHPBB论坛的默认URL规格改成以下文件里生成的格式，这里有具体方法：http://blog.youkuaiyun.com/huangqiaoling/article/details/7652111

注意红色部分的代码，要改成你网站对应的内容：
