由于工作的原因，最近需要生成网站的sitemap.xml,谷歌百度了很多地方，没有发现并合适可用的代码，三思之后还是决定自己写吧！虽然可能写的有所缺陷，但是毕竟是认认真真写的，希望对一些后来者有所帮助......
1、为什么要自己写脚本生成sitemap.xml?
很多人会说，在网上有现成的工具，扫一下就可以了，没有必要自己写。是的，的确是这样的。但是假设我们的网站进行经常更新，那么是不是每次我都要手动更新sitemap呢。我很懒，那么，有没有更好的方案呢？肯定是有的，我是否可以起一个定时任务，每天晚上更新一次呢，此时脚本就有用武之地了
2、文档目录：
配置文件 - config/config.ini.php
sitemap主文件 - SiteMap.class.php
3、主文件代码
