外观对象

<?php
/**
 * Facade
 *
 * @author     Luffy <lufei@swoole.com>
 * @date       2019/11/29
 * @copyright  Swoole, Inc.
 * @package    sy-records/design-patterns
 */
namespace Luffy\DesignPatterns\Facade;
class Facade
{
    /**
     * @var People
     */
    private $people;
    /**
     * @var Package
     */
    private $package;
    /**
     * Facade constructor.
     */
    public function __construct()
    {
        $this->people = new People();
        $this->package = new Package();
    }
    /**
     * 寄快递
     */
    public function send()
    {
        $this->people->say();
        $this->package->pickup();
        $this->package->inspection();
        $this->package->bale();
        $this->package->sendOut();
    }
}

子系统->人

<?php
/**
 * People
 *
 * @author     Luffy <lufei@swoole.com>
 * @date       2019/11/29
 * @copyright  Swoole, Inc.
 * @package    sy-records/design-patterns
 */
namespace Luffy\DesignPatterns\Facade;
class People
{
    public function say()
    {
        echo "下单寄快递\n";
    }
}

子系统->快递服务

<?php
/**
 * Package
 *
 * @author     Luffy <lufei@swoole.com>
 * @date       2019/11/29
 * @copyright  Swoole, Inc.
 * @package    sy-records/design-patterns
 */
namespace Luffy\DesignPatterns\Facade;
class Package
{
    public function pickup()
    {
        echo "上门取件\n";
    }
    public function inspection()
    {
        echo "验视\n";
    }
    public function bale()
    {
        echo "打包\n";
    }
    public function sendOut()
    {
        echo "寄出\n";
    }
}

客户端调用

<?php
/**
 * Client
 *
 * @author     Luffy <lufei@swoole.com>
 * @date       2019/11/29
 * @copyright  Swoole, Inc.
 * @package    sy-records/design-patterns
 */
namespace Luffy\DesignPatterns\Facade;
include __DIR__ . '/../vendor/autoload.php';
class Client
{
    public static function run()
    {
        $facade = new Facade();
        $facade->send();
    }
}
Client::run();
