Description:
------------
This may just be my mis-understanding of how the language should work,
but surely when you copy an object (class) and make changes to it,
those changes shouldn't affect the original object?
I don't really see the point in making a copy of an object, if the
changes you make to the new copy affect the old copy.
If I'm just dumb, then I apologise.
Reproduce code:
---------------
<?
class c {
var $i = 0;
};
$a = new c;
$a->i = 1;
$b = $a;
$b->i = 2;
echo "a: $a->i";
echo "b: $b->i";
?>
Expected result:
----------------
a: 1
b: 2
Actual result:
--------------
a: 2
b: 2
