Description:
------------
$that is not available in parent class B (uncomment code in class A you
will see it). So it is not possible to clone class in a recursive
way.
Reproduce code:
---------------
class A {
public $a;
function __clone(){
//if( $that === null ) die('$that is null');
$this->a = $that->a;
}
}
class B extends A {
public $b;
function __clone(){
parent::__clone();
$this->b = $that->b;
}
}
$b = new B();
$b->a = 'AAA';
$b->b = 'BBB';
$clone = $b->__clone();
print_r($clone);
Expected result:
----------------
B Object
(
[b] => BBB
[a] => AAA
)
Actual result:
--------------
B Object
(
[b] => BBB
[a] =>
)
