演示代碼：

1、model代碼

<?php
namespace MVC;
// use PDO;
class Model
{
    protected $dsn;
    protected $username;
    protected $password;
    protected static $db=null;
    public function __construct($dsn,$username,$password)
    {
        $this->dsn=$dsn;
        $this->username=$username;
        $this->password=$password;
        self::$db=new \PDO($this->dsn,$this->username,$this->password);
    }
    public function select($limit,$num)
    {
        $sql="select * FROM `staffs` LIMIT {$limit} OFFSET {$num}";
        $res=self::$db->query($sql);
        return $res->fetchAll(\PDO::FETCH_ASSOC);
    }
}

2、view代碼（略）
3、control代碼

<?php 
namespace MVC;
// 引入model和view
require 'Model.php';
require 'View.php';
// 準(zhǔn)備數(shù)據(jù)庫連接參數(shù)
$dsn='mysql:host=php.edu;dbname=php.edu;charset=utf8;port=3306';
$username='phpedu';
$password='123456';
// 服務(wù)容器
class Container
{
    protected $class_container=[];
    public function bind($class,\Closure $obj)
    {
        $this->class_container[$class]=$obj;
    }
    public function make($class,$params=[]){
        return call_user_func_array($this->class_container[$class],$params);
    }
}
$container=new Container;
$container->bind('model',function()use($dsn,$username,$password){return new Model($dsn,$username,$password);});
$container->bind('view',function (){return new View();});
// 控制類(外部model和view對象注入)
/*
class Control
{
    protected $model;
    protected $view;
    public function __construct(Model $model,View $view)
    {
        $this->model=$model;
        $this->view=$view;
    }
    public function html($n,$m)
    {
        $data=$this->model->select($n,$m);
        return  $this->view->index($data);
    }
}
$model=new Model($dsn,$username,$password);
$view=new View();
echo (new Control($model,$view))->html(5,10);
*/
// 控制類，面向服務(wù)容器的形式
class Control
{
    public function html(Container $container,$n,$m)
    {
        $data=$container->make('model')->select($n,$m);
        return  $container->make('view')->index($data);
    }
}
echo (new Control())->html($container,10,10);

4、control類門面技術(shù)：

//定義門面類
class Facades
{
    public static $class=null;
    public static $data=[];
    public static function class(Container $container)
    {
        static::$class=$container;
    }
}
//模型類靜態(tài)接口
class Model1 extends Facades
{
    public static function getdata($n,$m)
    {
        static::$data=static::$class->make('model')->select($n,$m);
    }
}
//視圖類靜態(tài)接口
class View1 extends Facades
{
    public static function index($data)
    {
        return static::$data=static::$class->make('view')->index($data);
    }
}
//控制類
class Control
{   protected $container;
    public function __construct(Container $container){
        $this->container=$container;
        Facades::class($this->container);
    }
    public function html($n,$m)
    {
        Model1::getdata($n,$m);
        return  View1::index(Facades::$data);
    }
    //自動銷毀服務(wù)容器
    public function __destruct()
    {
        $this->container=null;
    }
}
//客戶端代碼，匿名類使用完自動銷毀
echo (new Control($container))->html(12,10);

5、演示結(jié)果：

總結(jié)：

1、call_user_func_array():利用回調(diào)函數(shù)處理數(shù)組
2、MVC是一個經(jīng)典的：數(shù)據(jù)，視圖，控制器分離的代碼組織方法；
3、服務(wù)容器類：把所有需要實列化的類統(tǒng)一交給一個類來管理；
4、facades(門面技術(shù))是把服務(wù)容器中的對象（靜態(tài)接口）實現(xiàn)靜態(tài)化訪問；

批改老師：天蓬老師

批改狀態(tài)：合格

老師批語：容器, 門面, 都是對類成中的高度抽象和封裝, 目標(biāo)就是和用戶提供一個簡單方便的訪問接口
