Step One: Getting Started
How to use phpbean for routing and forwarding? Below is a simple usage example.
First of all, index.php is the single entry point of the program, which mainly performs routing and forwarding work. The program code of Index.php is as follows:

include('startup.php');//Load the startup file
try{
$router=new Phpbean_Router() ;//Initialize the router
$router->set_path(SITE_PATH.'/app/actions');//Set the directory of the controller
$router->dispatch();//Route forwarding processing
}catch (Exception $e){
echo $e;
}

?>

The startup file is as follows:

define('SITE_PATH',str_replace('','/',dirname(__FILE__)));
set_include_path(get_include_path().PATH_SEPARATOR.SITE_PATH.'/libs/');
function __autoload ($filename){
$filepath = SITE_PATH.'/libs/'.str_replace('_','/',$filename).'.php';
if(is_file($filepath)){
include($filepath);
}
}?>

Then, we write an action to test it. (As for why you choose action instead of using controller as control, you can read my previous article on gradually improving the performance of the framework)
For example, app/actions/indexAction.php, write a test in it
class indexAction extends Phpbean_Action {

function run(){
echo 'phpbean_index page!';
}?
}?>
Open IE and enter the address http://localhost :8080/phpbean/index.php/index to see the results.

Step 2: Get url parameters
For example, if I want to use url to pass parameters, how can I implement it in PHPbean? Pathinfo in phpbean supports two ways of obtaining data, one is by keyword and the other is by order (default).
Take the example just now, add the parameter http://localhost:8080/phpbean/index.php/index/1/2 after the address http://localhost:8080/phpbean/index.php/index /3/4/
Then, use keywords to get url parameters, use $this->_getParam('1','key'). For example, if you add echo $this->_getParam('1','key') in the run method of indexAction, the corresponding output will be 2. Note that getting url parameters by keyword in phpbean does not require matching pairs. For example, $this->_getParam('1','key') returns 2, $this->_getParam('2','key') will return 3.
Get the url parameters in order. More convenient. For example, $this->_getParam(1) will return 1, and $this->_getParam($n) will return the $nth parameter.

The third step, Action multi-level directory
Generally speaking, the design of the program is module->controller->action, such as blog->user->login. Then using phpbean's action can be easily mapped.

First, we add the blog folder under app/actions, and then add the user folder under app/actions/blog/.

Now let’s write the blog->user->login action. First create loginAction.php under app/actions/blog/user/. Write

class blog_user_loginAction extends Phpbean_Action {

function run(){
echo 'blog_user_login';
} }

}
?>

Then test http://localhost:8080/phpbean/index.php/blog/user/login/. Is it successful?

So, "How to add some common operations of actions? For example, all actions under the admin directory must be checked by isadmin(). How to implement this?" In phpbean, inheritance can be used to achieve this very conveniently. Let's take blog->admin as an example to implement this.
First, add an admin directory, and add an action base class admin.php in this directory (note that if it is not an action, do not use ***Action.php to name the file)

abstract class _blog_admin extends Phpbean_Action {

function __construct($params){
parent::__construct($params);
echo 'admin check! ';
}

}
?>

Then, all actions in the admin directory inherit from _blog_admin instead of Phpbean_Action, thus realizing public operations of packaging.For example, create a loginAction.php in the admin directory

class blog_admin_loginAction extends _blog_admin {

function run(){
echo 'blog_admin_login';
}

}
?>
