Bug description: this pointer is not passed by reference correctly
Description:
------------
When you pass the $this pointer by reference and change data for the
object it points to, that data is not correctly updated.
Reproduce code:
---------------
function changeAddress(&$oldThing) {
$oldThing = new Thing();
}
class Thing {
var $data;
public function updateData($newData) {
ThingChanger::changeData($this,$newData);
var_dump($this);
var_dump($this->data);
}
}
class ThingChanger {
public static function changeData(&$thingToChange,$newData) {
changeAddress($thingToChange);
$thingToChange->data = $newData;
}
}
$thing = new Thing();
$thing->data = "foo";
$thing->updateData("bar");
Expected result:
----------------
object(Thing)#2 (1) {
["data"]=>
string(3) "bar"
}
string(3) "bar"
Actual result:
--------------
object(Thing)#2 (1) {
["data"]=>
string(3) "bar"
}
string(3) "foo"
