Description:
------------
Before bug #30828 was fixed, debug_backtrace() could be used to get the name of a class when the class was extended from a parent class and being called statically.  The new change removes this functionality, and as far as I can see there is no replacement. Perhaps, I am just unaware of an alternative method of achieving this, but if not then this is a vital piece of functionality that has gone missing!


Reproduce code:
---------------
<?php

  function get_class_static() {
    $bt = debug_backtrace();
    if (isset($bt[1]['object']))
        return get_class($bt[1]['object']);
    else
        return $bt[1]['class'];
  }

  class foo {
    function printClassName() {
      print(get_class_static() . "<br>");
     }
  }

  class bar extends foo {
  }

foo::printClassName();
bar::printClassName();

?>

Expected result:
----------------
In PHP4 the output was:

foo
bar

Actual result:
--------------
In PHP5 the output is:

foo
foo
