Bug description: No way to get origional object from within __clone()
Description:
------------
When you clone an object the __clone method does not have a way to get a
reference to the original object.
It would be advantageous to have a way to get the original object from
within the __clone method.
One reason for this is that you can have an object that has child objects
that in-turn reference back to the parent object and on clone you want to
clone these child objects but would need to remove the original reference
and replace it with the new parent reference.
This feature could be implemented by simply passing the original object as
an argument to the __clone() method.
Reproduce code:
---------------
class Parent
{
protected $children = array();
public function __clone($originalThis)
{
$clonedChildren = array();
foreach($this->children as $child)
{
$childClone = clone $child;
$childClone->attach($this);
// we have no way of getting the original
// object do we cant do the following...
$childClone->detach($originalThis);
}
$this->children = $clonedChildren;
}
}
Expected result:
----------------
N/A
Actual result:
--------------
N/A
