Description:
------------
The manual says that array_multisort mantains key associations. This is only true if the keys are strings. If the keys are integers on the other hand, key association is not mantained. I don't think that this is a bug since it's so obvious. But I wish feedback on this to clear this issue up. Thanks alot!

Reproduce code:
---------------
<?
//names array. keys are user id's
$names[5]  = 'Peter';
$names[7]  = 'Jim';
$names[11] = 'Martin';
$names[33] = 'John';
$names[34] = 'Robert';

//age array. keys are user id's
$age[5]    = 15;
$age[7]    = 19;
$age[11]   = 54;
$age[33]   = 29;
$age[34]   = 17;

//sort names array by ages
array_multisort($age, $names);

var_dump($names);
?>

Expected result:
----------------
I expect this:

// _should_ return
//
// array
//   5  => 'Peter'
//   34 => 'Robert'
//   7  => 'Jim'
//   33 => 'John'
//   11 => 'Martin'

Actual result:
--------------
// returns the following for me
//
// array
//   0 => 'Peter'       
//   1 => 'Robert'
//   2 => 'Jim'   
//   3 => 'John'   
//   4 => 'Martin'
