How to implement php object cloning

Sometimes we need to use two or more identical objects in a project. If you use the "new" keyword to recreate the object and then assign the same attributes, it is more cumbersome and easier to do so. An error occurred, so it is very necessary to completely clone an identical object based on an object, and after cloning, the two objects will not interfere with each other. This article mainly shares with you the implementation method of PHP object cloning, hoping to help everyone.

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()."
"; echo "ee1 Name: ".$ee1->getName()."
"; echo "ee2 ID: ".$ee2->getID()."
"; echo "ee2 Name: ".$ee2->getName()."
"; ?>

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: ".$ee1->getID()."
"; echo "ee1 Name: ".$ee1->getName()."
"; echo "ee2 ID: ".$ee2->getID()."
"; echo "ee2 Name: ".$ee2->getName()."
"; ?>
