PHP Objects, Patterns and Frameworks PHP4 退出历史舞台， PHP5 成为主流 PHP5 对于面向对象的支持大大加强反射（ reflection ）、异常（ exception ）、私有和保护（ private 和 protected ）的方法和属性、 __toString() 方法、 static 修饰符、抽象类和抽象方法、 final 方法和属性、接口、迭代器（ iterator ）、拦截器（ interceptor ）方法、类型检查、 const 关键字、引用传递、 __clone() 方法和 __construct() 构造方法等等。面向对象的 PHP 开发设计模式的应用面向对象的 PHP 开发框架国内的 FleaPHP, ThinkPHP 等

场景：川菜馆顾客看菜谱顾客：来一盘鱼香肉丝服务员：好咯服务员告诉大厨： 2 号桌要一盘鱼香肉丝大厨辛苦劳动。。炒炒炒搞定。告诉服务员：炒好了。服务员把菜端给顾客 MVC 的含义 MODEL VIEW CONTROLLER

Zend Framework 开放源代码的 PHP5 开发框架易于学习和使用功能强大，促进快速开发有活跃的开发者社区和完善的支持平台 BSD 许可适合商业应用由 Zend 公司主导开发合作： 2008 Jolt Award

MVC in ZF Zend_Db_Table Zend_View Zend_Controller

MVC in ZF 单一入口： index.php 项目文件目录分布

Bootstrap ( 入口文件 ) <?php // 控制器实例化 $controller = Zend_Controller_Front :: getInstance (); $controller -> setControllerDirectory ( $controllerDir ); // 设置路由 $router = new Zend_Controller_Router_Route_Rewrite (); $controller -> setRouter ( $router ); // 设置请求对象 $request = new Zend_Controller_Request_Http (); $controller -> setRequest ( $request ); $controller -> throwExceptions ( true ); $controller -> returnResponse ( true ); // 得到响应对象 $response = $controller -> dispatch (); // 输出 echo $response ; ?>

Zend_Controller 用户访问： http://www.phpeye.com/article/view/id/1 Apache Server: url_rewrite 转向所有请求到入口文件 index.php index.php 初始化控制器 Router 对 URL 进行分解根据路由规则，决定调用哪个 controller 中的哪个 action Dispatcher 调用 controller 中的 action

Zend_Controller Zend_Controller_Front 设置 controller 目录，生成 request 对象，并 dispatch() Zend_Controller_Request_Abstract 默认使用 Zend_Controller_Request_Http Zend_Controller_Router_Interface 决定调用哪个 Controller 中的哪个 Action Zend_Controller_Dispatcher_Interface 调用 controller 中的 Action

Zend_Controller class ArticleController extends Zend_Controller_Action { public function indexAction () { } public function viewAction () { $articleId = $this->request-> getParam(‘id’); $article = $this->article->find($articleId); $this->view->article = $article; $this->view->render();// 不需要指定模板 } } http://www.phpeye.com/article/ -> indexAction() http://www.phpeye.com/article/view/id/1 -> viewAction()

Model - DB 1. 数据库软件的抽象基于 PDO (PHP Data Objects) MySQL, OCI, PostgreSQL, ODBC, DB2, SQLite, Sybase/FreeTDS/MSSQL 2. SQL 抽象多个层次 Zend_Db 手写 Sql $this->db->query($sql); Zend_Db_Select 部分手写 Zend_Db_Table 基本不用写 Sql Zend_Db_Table_Row Row Data Gateway Zend_Db_Table_Rowset 数据库访问抽象的两个层次

Table Data Gateway An object that acts as a Gateway to a database table. One instance handles all the rows in the table.

Active Record An object that wraps a row in a database table or view, encapsulates the database access, and adds domain logic on that data.

CRUD Zend_Db_Table $rows_affected = $this->insert($data); $rows_affected = $this->update($data, $where); $rows_affected = $this->delete($where); $rowset = $this->find($id); Zend_Db $this->db->query($sql);

Zend_View <html> <head> <title ><?php echo $title ?></title> </head> <body> <?php echo $body ?> </body> </html>

Zend_View PHP is template language itself. You don’t need another one. Just separate your logic from your presentation. View Renderer Compatible with other template systems, such as Smarty, HTML_Template_PHPLIB, etc.
