Description:
------------
It would be quite handy were there an option (optional 3rd parameter) to array_change_key_case so that it would recurse into multi-dimensional arrays so one would not need to create work arounds such as:

function ack_r($array, $case) 
{
  $array = array_change_key_case($array, $case);
  foreach ($array as $key => $value) {
    if ( is_array($value) ) {
      $array[$key] = ack_r($value, $case);
    }
  }
  return $array;
}

Re-requested in request #52917.

another way to do it:

    function ack_r3(&$array, $case=CASE_LOWER, $flag_rec=false) 
    {
      $array = array_change_key_case($array, $case);
      if ( $flag_rec ) {
        foreach ($array as $key => $value) {
            if ( is_array($value) ) {
                ack_r3($array[$key], $case, true);
            }
        }
      }
    }

note that: ack_r3($array, $case, false) <=> array_change_key_case($array, $case)

I don't see much point in adding this feature to php-src, since it
can trivially be implemeted in userland code, and there doesn't
appear to big downside in doing so.

If anybody still feels strongly about this, please pursue the RFC
process[1].
