首先--添加dll,修改php.ini--不同的版本,不同的需求
其次,根据教程http://www.laruence.com/manual/tutorial.firstpage.html#tutorial.directory手动搭建好目录结构
入口文件index.php位置稍作修改--个人习惯
入口文件内容
<?php header("Content-Type: text/html;charset=utf-8"); define("APP_PATH", realpath(dirname(__FILE__) . '/../')); /* 指向public的上一级 */ $app = new Yaf_Application(APP_PATH . "/yaf/conf/application.ini"); $app->run();
配置文件
配置文件内容
[product]
;支持直接写PHP中的已定义常量
application.directory=APP_PATH "/yaf/application"
集成了一个数据库操作类
控制器写法
new DBModel();的意思是去models文件夹下找DB.php里的DBModel类
DB.php
