PHP object replication, is a copy of the object's reference address, so use $objA = $objB this style, $objA and $OBJB will point to the same memory address. $objB can also be affected when the $obja is changed. If we want to replicate $obja objects

To eliminate cloning, you might think that you simply set the Clone () method to private (private), but it doesn't work because you can't take a basic class method and make it more "private" in a derived class. So it's not that simple. In addition,
