What does php controller mean?

Implementation of the Controller layer in PHP

The role of the Controller is usually to obtain and exchange data in the Model. Let the View display it, so how should we write it during development?

1. Create the class file of Controller. My file name is MatchController.class.php

<?php /**
 * 比赛操作相关控制器功能类 
 */
class MatchController{
    /**
     * 比赛列表操作
     */
    public function listAction(){
        header(&#39;Content-Type: text/html;charset=utf-8&#39;);
        //实例化相应的模型类对象，调用某个方法，实现固定功能
        // require &#39;./MatchModel.class.php&#39;;
        // $m_match = new MatchModel();
        //通过工厂获得对象
        require &#39;./Factory.class.php&#39;;
        $m_match = Factory::M(&#39;MatchModel&#39;);
        $match_list = $m_match->getList();
        // $m_match2 = Factory::M('MatchModel');

        // 载入负责显示的html文件
        require './template/match_list_v.html';
    }
    /**
     * 比赛删除
     */
    public function removeAction(){
        
    }
}

2. Instantiate the controller object (front-end controller or request dispatcher) in the entry file ), the file name is index.php

In order to allow index.php to perform the actions we want to operate, some parameters should be passed to index.php to tell the entry file how to do it.
If we want to delete a game information in the game list (Game Controller), we can pass the parameters to index.php like this:

index.php?c=match&a=remove&id=N

The corresponding HTML file should be written like this:

Pass parameters to index.php through click events

index.php:

<?php //动作
$default_action = &#39;list&#39;;
$a = isset($_GET[&#39;a&#39;])?$_GET[&#39;a&#39;]:$default_action;

//实例化控制器类
require &#39;./MatchController.class.php&#39;;
//实例化
$controller = new MatchController();
//调用方法
$action_name = $a.&#39;Action&#39;;
$controller -> $action_name();//可变方法
