PHP design pattern abstract factory-PHP Tutorial-php.cn

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:

"; } } /** 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(); } }

"; $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 "
"; echo "-----------------创建第二个英雄-----------------
"; $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.
