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.
