In PHP 5 Release Candidate 3 the problem still exists.

So, there is a problem with serialization and deserialization of
objects with references to others objects.

5.0.0 RC2, Win32

----------------------------------
<?php
class MyClass
{ public $number;
function EchoNum()
{ echo $this->number;
echo "<br>";
}
}

$a = new MyClass;
$a->number = 1;

$b = $a;
$b->number = 2;

$a->EchoNum();
$b->EchoNum();
?>

outputs:

2
2

----------------------------------
but...

<?php
class MyClass1
{ public $myclass2;
}

class MyClass2
{ public $myclass1;
}

$a = new MyClass1;
$a->myclass2 = new MyClass2;

$a->myclass2->myclass1 = $a;
$a->number = 1;
echo $a->myclass2->myclass1->number;
echo "<br>";

$c = serialize($a);
echo $c;

echo "<br><br>";

$b = unserialize($c);

$b->number = 2;
echo $b->number;
echo "<br>";
echo $b->myclass2->myclass1->number;
echo "<br>";
echo "<br>";
?>

outputs:

1
O:8:"MyClass1":2:{s:8:"myclass2";O:8:"MyClass2":1:{s:8:"myclass1";O:8:"MyClass1":2:{s:8:"myclass2";r:2;s:6:"number";i:1;}}s:6:"number";i:1;}

2
1
----------------------------------

while:

<?php
class MyClass1
{ public $myclass2;
}

class MyClass2
{ public $myclass1;
}

$a = new MyClass1;
$a->myclass2 = new MyClass2;

$a->myclass2->myclass1 = &$a; <--- ampersand symbol added
$a->number = 1;
echo $a->myclass2->myclass1->number;
echo "<br>";

$c = serialize($a);
echo $c;

echo "<br><br>";

$b = unserialize($c);

$b->number = 2;
echo $b->number;
echo "<br>";
echo $b->myclass2->myclass1->number;
echo "<br>";
echo "<br>";
?>

works fine and outputs:

1
O:8:"MyClass1":2:{s:8:"myclass2";O:8:"MyClass2":1:{s:8:"myclass1";r:1;}s:6:"number";i:1;}
