范例

Example #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

Example #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();
?>

Example #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",
  )
}

Example #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

Example #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";
   }
}
?>

Example #6 默认视图文件

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

Example #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。

I success in "application" directory set to:

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

And Bootstrap.php should be enter at least 3 line like these:

<?php
class Bootstrap extends Yaf_Bootstrap_Abstract {
}

the nginx rewrite rule should be:

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

Alternative

you can generate the example above by using Yaf Code Generator: https://github.com/laruence/php-yaf/tree/master/tools/cg

use  nginx  and php-fpm   you can   config:

    location / {
        try_files $uri    $uri/    /index.php$is_args$args;
        }

        location ~ \.php$ {
                fastcgi_pass   127.0.0.1:9000;
               #fastcgi_pass unix:/tmp/php-cgi.sock;
                fastcgi_index  index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include        fastcgi_params;
        }

When you use nginx & php-fpm config for yaf frame, you must set PATH_INFO support in nginx. Otherwise, it will not work.
Demo :
location / {
  try_files $uri $uri/ @path_rw;
}

#path_info is needed by some php frameworks like yaf/thinkphp
location @path_rw {
  rewrite ^/(.*)$  /index.php/$1 last;
}

location ~ \.php {
  fastcgi_pass unix:/dev/shm/php-cgi.sock;
  fastcgi_index index.php;
  include fastcgi.conf;

  fastcgi_split_path_info ^(.+?\.php)(/.+)$;
  fastcgi_param SCRIPT_FILENAME   $document_root$fastcgi_script_name;
  fastcgi_param SCRIPT_NAME $fastcgi_script_name;
  fastcgi_param PATH_INFO $fastcgi_path_info;
}

Lost default Bootstrap.php

<?php
   /* bootstrap class should be defined under ./application/Bootstrap.php */
   class Bootstrap extends Yaf_Bootstrap_Abstract {
        public function _initConfig(Yaf_Dispatcher $dispatcher) {
            var_dump(__METHOD__);
        }
        public function _initPlugin(Yaf_Dispatcher $dispatcher) {
            var_dump(__METHOD__);
        }
   }
