Portal File

The entry file is the entrance of all requests. Generally, all requests are redirected to this entry file by using the rewrite rules.

A classic portal file public/index. php

<?("APP_PATH",  (() . '/../'));   =  Yaf_Application(APP_PATH . "/conf/application.ini"->run();

Rewrite Rules

Unless we use the query string-based routing protocol (Yaf_Route_Simple, Yaf_Route_Supervar), we need to use the Rewrite rules provided by WebServer to request all the applications, all are directed to the above-mentioned entry file.

Nginx Rewrite (nginx. conf)

 (!-^/(.*)  /index.php/$

Configuration File

In Yaf, configuration files support inheritance and can be segmented. and supports PHP constants. you don't have to worry about parsing performance problems caused by too many configuration files, because Yaf will load the configuration file at the first run and keep the formatted content in the memory. it will not be loaded again until the configuration file has been modified.

A simple configuration fileapplication/conf/application.ini

= APP_PATH  = = = =

Controller

In Yaf, the default modules, controllers, and actions are all named after indexes. Of course, this can be modified through the configuration file.

For the default module, the Controller directory is under the controllers directory under the application directory, and the Action naming rule is "name + Action"

Default Controllerapplication/controllers/Index.php

 

<? IndexController   indexAction() {       ->getView()->assign("content", "Hello World"?>

View File

Yaf supports simple view engines and allows you to customize your own view engines, such as Smarty.

For the default module, the path of the View File is in the directory named lower-case action in the views directory under the application directory.
