2、首页静态化
首页静态化，可通过ob缓存，通过后台动态页面定时生成首页内容，替换旧页面
两个技术：ob缓存控制页面输出到一个html静态页面中、模板替换技术把模板替换成有内容的特定页面
简单代码：
数据库 news表 字段 id title content
manage.html
View Code1 html 2 head 3 meta http-equiv="content-type" content="text/html;charset=utf-8"/ 4 title 管理新闻 /title 5 /head 6 body 7 h1 管理新闻 /h1 8 hr / 9 a href="add.html" 添加新闻 /a ||10 a href="newsList.php" 更新首页 /a ||11 a href="showNews.php" 查看新闻列表 /a 12 /body 13 /html
