The example in this article describes how to implement object cloning in PHP. Share it with everyone for your reference. The details are as follows:
<?php //定义类staff,其中包括属性id和name class staff { private $id; private $name; function setID($id) { $this->id = $id; } function getID() { return $this->id; } function setName($name) { $this->name = $name; } function getName() { return $this->name; } } //创建一个新的staff对象并初始化 $ee1 = new staff(); $ee1->setID("145"); $ee1->setName("Simon"); //克隆一个新的对象 $ee2 = clone $ee1; //重新设置新对象的ID值 $ee2->setID("146"); //输出ee1和ee2 echo "ee1 ID: ".$ee1->getID()."<br>"; echo "ee1 Name: ".$ee1->getName()."<br>"; echo "ee2 ID: ".$ee2->getID()."<br>"; echo "ee2 Name: ".$ee2->getName()."<br>"; ?>
<?php //定义类staff,其中包括属性id和name class staff { private $id; private $name; function setID($id) { $this->id = $id; } function getID() { return $this->id; } function setName($name) { $this->name = $name; } function getName() { return $this->name; } //这里是__clone函数 function __clone() { $this->id = $this->id + 1; } } //创建一个新的staff对象并初始化 $ee1 = new staff(); $ee1->setID("145"); $ee1->setName("Simon"); //克隆一个新的对象 $ee2 = clone $ee1; //重新设置新对象的ID值 //$ee2->setID("146"); //输出ee1和ee2 echo "ee1 ID: ".$ee1->getID()."<br>"; echo "ee1 Name: ".$ee1->getName()."<br>"; echo "ee2 ID: ".$ee2->getID()."<br>"; echo "ee2 Name: ".$ee2->getName()."<br>"; ?>
I hope this article will be helpful to everyone’s PHP programming design.
