Bug description: New object model fails - old style works fine
Description:
------------
You have a main object which includes some other
objects. This object is stored in the session. The
other objects have a reference to the main object. If
you start a new session these references should point to
the main object. If you pass the objects to the main
object in the old style with "&" this works fine. If you
use the new style without "&" it doesn't work as
exspected.
Reproduce code:
---------------
The classes:
class CHello
{
var $store;
// this doesn't work as exspected
public function CHello($store)
{
$this->store = $store;
}
/*
// this works fine
public function CHello(&$store)
{
$this->store =& $store;
}
*/
public function hello( )
{
$v = $this->store->value;
echo "Hello World: value is $v. (store id: $this->store)<br>";
}
}
class CStore
{
var $object1;
var $object2;
var $value = 0;
}
---------------------------
The first script:
session_start();
$store = new CStore;
$hello1 = new CHello($store);
$hello2 = new CHello($store);
$store->value = 999;
$store->object1 = $hello1;
$store->object2 = $hello2;
echo "store id: $store<br>";
$store->object1->hello();
$store->object2->hello();
session_register("store");
---------------------------
The second script:
session_start();
$store->value = 123;
echo "store id: $store<br>";
echo $store->object1->hello();
echo $store->object2->hello();
Expected result:
----------------
The first script where the objects are generated:
store id: Object id #4
Hello World: value is 999. (store id: Object id #4)
Hello World: value is 999. (store id: Object id #4)
The second script:
store id: Object id #1
Hello World: value is 123. (store id: Object id #1)
Hello World: value is 123. (store id: Object id #1)
Actual result:
--------------
The first script where the objects are generated:
store id: Object id #6
Hello World: value is 999. (store id: Object id #6)
Hello World: value is 999. (store id: Object id #6)
The second script:
store id: Object id #1
Hello World: value is 999. (store id: Object id #3)
Hello World: value is 999. (store id: Object id #5)
