PHP--Facades门面技术MVC视图渲染（进阶三）

Facades门面技术

<?php
//facades门面技术
require 'model.php';
require 'view.php';
//1，服务容器
class container
{
    protected $instances = [];
    public function bind($alias,\Closure $process)
    {
        $this->instances[$alias] = $process;
    }
    public function make($alias,$params=[])
    {
        return call_user_func_array($this->instances[$alias],[]);
    }
}
$container=new container;
$container->bind('Model',function(){return new Model;});
$container->bind('View',function(){return new View;});
//2，facades门面技术
class facades
{
    protected static $container=null;
    protected static $data=[];
    // 初始化方法: 从外部接收一个依赖对象: 服务容器的实例
    public static function initialize(container $container)
    {
        static::$container = $container;
    }
}
class M extends facades
{
    public static function getData()
    {
        static::$data= static::$container->make('Model')->getData();
    }
}
class V extends facades
{
    public static function fetch()
    {
        return static::$data = static::$container->make('View')->fetch(static::$data);
    }
}
//3，控制器
class controller
{
    public function __construct(container $container)
    {
        facades::initialize($container);
    }
    public function index()
    {
        M::getData();
        return V::fetch();
    }
}
$controller=new controller($container);
echo $controller->index();

总结：运行原理应该是这样的；从底层开始（控制器）-上移->Facades门面-上移->服务容器。往上接管！代码看的懵！
