Description:
------------
Why the recursive call of array_walk_recursive() doesn't the exact parameter it needs ? The first and second arguments are OK ($item and $funcname) but the third give the complete array , so the function receive $item and $funcname and an array containing $item, $funcname and the $userdata variable.

Then in the funcname function, if you use the $userdata parameter, you have to think that the parameters is the array and the $userdata is the third value of this array !

Test script:
---------------
// Line 56 of the code in the 1.7 version
// array_walk_recursive($item, $funcname, $args);

// My proposition
// array_walk_recursive($item, $funcname, $args[2]);

// function to call
function test_userdata(&$item, $key, $userdata)
{
$item = $userdata . ' - ' . $item;
}

$a = array(array('test11', 'test12', 'test13'), 'test2', array('test31', 'test32'));

array_walk_recursive($a, 'test_userdata', 'print userdata');

print_r($a);

Expected result:
----------------
Array
(
[0] => Array
(
[0] => print userdata - test11
[1] => print userdata - test12
[2] => print userdata - test13
)

[1] => print userdata - test2
[2] => Array
(
[0] => print userdata - test31
[1] => print userdata - test32
)

)

Actual result:
--------------
Array
(
[0] => Array
(
[0] => Array - test11
[1] => Array - test12
[2] => Array - test13
)

[1] => print userdata - test2
[2] => Array
(
[0] => Array - test31
[1] => Array - test32
)

)
