Introduction
In this article, we will study cloning of objects, how to make a cloned object.
Creating a copy of an object with fully replicated properties is not always the intended behavior and the meaning of clone is that there exists multiple identical copies of an original one. A cloned object is created by using the clone keyword that is called implicitly, and it is not possible to call the method explicitly. So the term cloning means make a copy of an old object to a new variable but the clone method cannot be called directly. When we make a clone of an object it will be called to allow any change in the properties that need to change. If you want to implement a copy constructor in PHP, then you can use the clone method to implement the copy constructor in PHP.
In simple words, cloning creates a genuine copy of an object. Assigning an object to another variable does not create a copy, it creates a reference to the same memory location as the object. Cloning an object creates a "shallow" copy of the original object. What this means is that any properties that reference other variables will remain references to those variables and not copies of them.
Example
<?php
class Myclass
{ static $instances=0;
public $instance;
function __construct()
{ $this->instance=++self::$instances;
}
function __clone()
