PHP design pattern abstract factory

This article introduces the abstract factory of PHP design pattern, which has certain reference value. Now I share it with you. Friends in need can refer to it

After learning the factory method, the factory method I know is basically to create an object.
For example, when playing a game, I created a Guan Yu hero and a Zhang Fei hero.

But sometimes you may need to create a group of objects during programming, and this leads to the second creational design pattern-- Abstract Factory Method (AbstractFactory).
For example, when I created Guan Yu, I was holding the Qinglong Yanyue Sword and riding a red rabbit horse.
When Liu Bei was created, he held both male and female swords in his hands and rode a horse.
Then their weapons need one class to implement, and the horse needs another class to implement.
Characters, weapons and mounts become a combination.

Finally, the combination creation is achieved through an abstract factory pattern.

The recording code is as follows:

<?php    

  
/** Hero 
 *  定义一个英雄接口 
 */  
interface Hero  
{  
    function CreateHero();  
}  
  
/** GuanYu 
 *  关羽英雄类 
 */  
Class GuanYu implements Hero  
{  
    function CreateHero()  
    {  
         echo "关羽加入战场-->";  
    }   
}  
  
/** LiuBei 
 *  刘备英雄类 
 */  
Class LiuBei implements Hero  
{  
    function CreateHero()  
    {  
         echo "刘备加入战场-->";         
    }  
}  
  
  
/** Weapon 
 *  定义一个兵器接口 
 */  
interface Weapon  
{  
    function CreateWeapon();  
}  
  
/** GuanYuWeapon 
 *  青龙偃月刀的类 
 */  
Class GuanYuWeapon implements Weapon  
{  
    function CreateWeapon()  
    {  
        echo "手持青龙偃月刀-->";         
    }  
}  
  
/** LiuBeiWeapon 
 *  雌雄双剑的类 
 */  
Class LiuBeiWeapon implements Weapon  
{  
    function CreateWeapon()  
    {  
        echo "手持雌雄双剑-->";          
    }  
}  
  
  
/** Horse 
 *  定义一个坐骑接口 
 */  
interface Horse  
{  
    function CreateHorse();  
}  
  
/** ChiTu 
 *  赤兔马类 
 */  
Class ChiTu implements Horse  
{  
    function CreateHorse()  
    {  
        echo "脚蹬赤兔马。";    
    }  
}  
  
/** DiLu 
 *  的卢马类 
 */  
Class DiLu implements Horse  
{  
    function CreateHorse()  
    {  
        echo "脚蹬的卢马。";    
    }     
}  
  
/** AbstractFactory 
 *  抽象工厂接口  为子类建立标准 
 *  LoadingHero   加载人物类方法 
 *  LoadingWeapon 加载武器类方法 
 *  LoadingHorse  加载坐骑类方法 
 */  
interface AbstractFactory  
{  
    function LoadingHero();  
    function LoadingWeapon();  
    function LoadingHorse();  
}  
  
/** GFactory 
 *  关羽英雄创建工厂类  用于客户端调用 
 */  
Class GFactory implements AbstractFactory  
{  
    function LoadingHero()  
    {  
        return new GuanYu();  
    }  
    function LoadingWeapon()  
    {  
        return new GuanYuWeapon();  
    }  
    function LoadingHorse()  
    {  
        return new ChiTu();  
    }          
}  
  
/** LFactory 
 *  刘备英雄创建工厂类  用于客户端调用 
 */  
Class LFactory implements AbstractFactory  
{  
    function LoadingHero()  
    {  
        return new LiuBei();  
    }  
    function LoadingWeapon()  
    {  
        return new LiuBeiWeapon();  
    }  
    function LoadingHorse()  
    {  
        return new DiLu();  
    }     
}

<?php   
  
// 抽象工厂模式  index.php    
header("Content-Type:text/html;charset=utf-8");  
  
require_once "AbstractFactory.php";  
  
echo "-----------------创建第一个英雄-----------------<br/>";  
$GY = new GFactory(); // 调用第一个英雄的工厂  
  
// 加载各自的创建方法  
$GYHero = $GY->LoadingHero();  
$GYWeapon = $GY->LoadingWeapon();  
$GYHorse = $GY->LoadingHorse();  
  
// 生成加入战场  
$GYHero->CreateHero();  
$GYWeapon->CreateWeapon();  
$GYHorse->CreateHorse();  
  
echo "<br/>";  
  
echo "-----------------创建第二个英雄-----------------<br/>";  
$LB = new LFactory(); // 调用第一个英雄的工厂  
  
// 加载各自的创建方法  
$LBHero = $LB->LoadingHero();  
$LBWeapon = $LB->LoadingWeapon();  
$LBHorse = $LB->LoadingHorse();  
  
// 生成加入战场  
$LBHero->CreateHero();  
$LBWeapon->CreateWeapon();  
$LBHorse->CreateHorse();

The output result:

-------------- ---Create the first hero-----------------
Guan Yu joins the battlefield--> Holding the Qinglong Yanyue Sword--> Pedal Red rabbit horse.
-----------------Create a second hero-----------------
Liu Bei joins the battlefield--> holding both male and female swords--> Luma on foot.
