浅析php原型模式

<?php
/**
 * 原型模式

//声明一个克隆自身的接口
interface Prototype {
    function copy();
}  
//产品要实现克隆自身的操作
class Student implements Prototype {
       //简单起见，这里没有使用get set
    public $school;
    public $major;
       public $name;
       public function __construct($school, $major, $name) {
              $this->school = $school;

              printf("%s,%s,%sn", $this->school, $this->major, $this->name);
       }
    public function copy() {
           return clone $this;
    }
}
$stu1 = new Student('清华大学', '计算机', '张三');
$stu1->printInfo();
$stu2 = $stu1->copy();
$stu2->name = '李四';
$stu2->printInfo();
