范例

示例 #1 一个典型的应用目录结构

- index.php 
- .htaccess 
+ conf
  |- application.ini //application config
- application/
  - Bootstrap.php   
  + controllers
     - Index.php //default controller
  + views    
     |+ index   
        - index.phtml //view template for default action
  + modules 
  - library
  - models  
  - plugins 

示例 #2 入口文件

顶层目录下的index.php是整个应用的唯一入口,应该把所有请求都重定向到这个文件(在Apache+php_mod模式下可以使用.htaccess)。

<?php
define("APPLICATION_PATH",  dirname(__FILE__));

$app  = new Yaf_Application(APPLICATION_PATH . "/conf/application.ini");
$app->bootstrap() //call bootstrap methods defined in Bootstrap.php
 ->run();
?>

示例 #3 重写规则

#for apache (.htaccess)
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* index.php

#for nginx
server {
  listen ****;
  server_name  domain.com;
  root   document_root;
  index  index.php index.html index.htm;

  if (!-e $request_filename) {
    rewrite ^/(.*)  /index.php/$1 last;
  }
}

#for lighttpd
$HTTP["host"] =~ "(www.)?domain.com$" {
  url.rewrite = (
     "^/(.+)/?$"  => "/index.php/$1",
  )
}

示例 #4 应用配置文件

[yaf]
;APPLICATION_PATH is the constant defined in index.php
application.directory=APPLICATION_PATH "/application/" 

;product section inherit from yaf section
[product:yaf]
foo=bar

示例 #5 默认控制器

<?php
class IndexController extends Yaf_Controller_Abstract {
   /* default action */
   public function indexAction() {
       $this->_view->word = "hello world";
       //or
       // $this->getView()->word = "hello world";
   }
}
?>

示例 #6 默认视图文件

<html>
 <head>
   <title>Hello World</title>
 </head>
 <body>
   <?php echo $word;?>
 </body>
</html>

示例 #7 运行应用

以上例程的输出类似于:

<html>
 <head>
   <title>Hello World</title>
 </head>
 <body>
   hello world
 </body>
</html>

Note:

在yaf@github上有Yaf代码生成器,你也可以用它来生成上面的例子。
