        foreach ($params as $key => $val)
        {
                if (is_array($val))
                {
                    $subPre = ($pre=="") ? $key : $pre . "[" . $key . "]";
                    //$pre = "[" . $key . "]";
                    $result = array_merge($result, toPost($val, $subPre));

                }
                else
                {
                    $result[$pre."[".$key."]"] = $val;
