PHP Design Patterns Prototype Pattern

The content of this article is about the prototype mode of PHP design pattern, which has certain reference value. Now I share it with everyone. Friends in need can refer to it

Prototype It’s not difficult to understand.

To sum up, it is to create objects through a cloning method to save the complexity of creating objects.

It can be mainly used to prevent a lot of code redundancy caused by repeatedly creating objects.

The recording code is as follows:

<?php  
/** 抽象原型类 
 *  abstract Class Prototype 
 */  
abstract Class Prototype  
{  
    abstract function Cloned();  
}  
  
  
/** 英雄类 继承抽象类 
 *  Class Hero 
 */  
class Hero extends Prototype  
{  
    public $weapon; // 武器变量  
  
    function Create()  
    {  
        echo "英雄已经创建完成，手里拿着";  
    }  
  
    // 克隆方法  
    function Cloned()  
    {  
        return clone $this;// PHP clone方法  
    }  
}

<br/>

weapon = "琉璃琴"; // 添加武器  
  
// 第二次通过克隆一号英雄 得到二号英雄  
$hero2 = $hero1->Cloned();  
  
$hero1->Create();  
echo "=>{$hero1->weapon}<br/>";  
  
// 克隆 会将类里面的函数和变量复制一份  
$hero2->Create();  
echo "=>{$hero2->weapon}<br/>";

##The output result is:

The hero has been The creation is completed, holding the Liuli Qin in hand=>Liu Li Qin
The hero has been created, holding the Liu Li Qin
