By the way, it is possible to change object attributes as if both were
passed by reference.
class foo {
public $bar;
}
function change($obj) {
$obj->bar = 1;
$obj = null;
}
$o = new foo;
change($o);
var_dump($o);
The result of this is:
object(foo)#1 (1) {
["bar"] => int(1)
}

Description:
------------
When trying to reassign an object inside a function, it is not acting
as passed by reference.
Reproduce code:
---------------
<?php
class foo {
}
function change($obj) {
$obj = null;
}
function change_ref(&$obj) {
$obj = null;
}
$o = new foo;
change($o);
var_dump($o);
change_ref($o);
var_dump($o);
Expected result:
----------------
Both should yield the same result.
1st: NULL
2nd: NULL
Actual result:
--------------
Only change_ref is redefining the object.
1st:
object(foo)#1 (0) {
}
2nd: NULL
