Bug description: unable to unset reference
Description:
------------
Hello,
First of all I would like to know if one day we will be able to unset
$this into a class in order to destroy the object. It could really be
useful to prevent big memory usage.
As it can't be done I tried to unset an object by unsetting a reference
of this object but it has no effect on the object but only on the
reference.
Should unset destroy the reference itself and the object ???
if you don't think so can you think of something different to destroy both
of them like I don't know, destroy($obejctsreference)
Regards.
Reproduce code:
---------------
<?
$x = new stdClass();
$x->a = 'ayayaye';
$b[0] =& $x;
unset($b[0]);
var_dump($x);
?>
Expected result:
----------------
NULL
Actual result:
--------------
object(stdClass)#1 (1) {
["a"]=>
string(7) "ayayaye"
}
