[PHP-BUG] Bug #52332 [NEW]: Static Member Reference Not Updating

[kolb0057 at umn dot edu]

From: 
Operating system: Windows XP Home SP3
PHP version:  5.2.13
Package:  Class/Object related
Bug Type: Bug
Bug description:Static Member Reference Not Updating

Description:

When an object's member is assigned as a reference to a different class'
static member and that static member is itself later assigned by reference,
the original object member's reference is not being updated.





I posted this question to the PHP General Mailing List.  One user confirmed
the bug for V5.0.0 to V5.3.3RC2.  In case you would like to search the
archive, the subject of the email was Static Class Member References.

Test script:
---
?php

class A

{

  public static $a = 3;

}



class B 

{

public $b;



public function assign()

{

$this-b = A::$a;

}

}



$b = new B;

$a = new A;

$b-assign();

A::$a = $a;



var_dump($b-b); // expected: object(A) | result: int 3

?

Expected result:

I expect 'var_dump($b-b);'  to print: object(A).

Actual result:
--
'var_dump($b-b);' is actually printing 'int 3'.
