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:

<&#63;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>"; 
&#63;> 

<&#63;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>";
