Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Sorry, you have a complete wrong idea og OO programming.

Static methods are bound/resolved at compile time. That is the compiler
can replace self with the current class.

Description:
------------
The issue is pretty simple I've explained this problem before, I'm
unsure why it hasn't been addressed - it's a design flaw and violates
basic principles of what you'd expect from an OOP language.

Consider a static function in a base class, and a class that inherits
from the above. In such a static function, self:: always refers to the
class where the code was declared. That is wrong, it should be relative
to the class the code was called from. It makes it impossible to have
seperate variables in sub-classes sharing the same code.

It is easier watching the example, it speaks for itself. When "test()"
runs, on the second call, it should be running within context of
ClassB, not ClassA.

This is related to bug #28442, which was apparently ignored. Can
someone at least explain what is the reasoning behind it working like
that? I don't want to sound rude, but I know how it works, the
distinctions between public and private, please don't patronize me
(again). :)

Reproduce code:
---------------
class ClassA
{
   private static $base    = "Variable from ClassA";
   static function   test()
   {
      print( self::$base . "\n" );
   }
}

class ClassB extends ClassA
{
   private static $base = "Variable from ClassB";
}

ClassA::test();
ClassB::test();


Expected result:
----------------
Variable from ClassA
Variable from ClassB

Actual result:
--------------
Variable from ClassA
Variable from ClassA
