Description:
------------
I have reference to array and iterating through the array using current()/next() loop

The problem is, that $element = current($arr_ref) returns always the first element in array regardless of multiple next($arr_ref) calls before current(...)

-----

It worked in php4.4.0. At the moment the only workaround is to replace everywhere in code:
  $element = current ($arr_ref)
to
  $element = current(& $arr_ref);

Reproduce code:
---------------
$a = array('foot', 'bike');

reset ($a);
next($a);
echo "A:" . current ($a) . "<BR>";


$b =& $a;

reset ($b);
next($b);
echo "B:" . current ($b) . "<BR>";

Expected result:
----------------
A:bike
B:bike

Actual result:
--------------
A:bike
B:foot
