Description:
------------
array_walk_recursive simply refuses to do anything whatsoever (even with the example code in the PHP docs!), while array_walk works fine.

Please note:
I am using PHP 5.0.2 and not PHP5.0.3 because I am unable to us ethe latter due to another bug I reported, still open here: http://bugs.php.net/bug.php?id=31175

Reproduce code:
---------------
(taken from http://www.php.net/manual/en/function.array-walk-recursive.php)

$sweet = array('a' => 'apple', 'b' => 'banana');
$fruits = array('sweet' => $sweet, 'sour' => 'lemon');

function test_print($item, $key) 
{
   echo "$key holds $item\n";
}

array_walk_recursive($fruits, 'test_print');

Expected result:
----------------
a holds apple
b holds banana
sour holds lemon 

Actual result:
--------------
[nothing, just blank!]
