What's about :

Code:

function list_date_email($d1,$m1,$d2,$m2,$limit,$pgoffset)
{    

    $query_string = "SELECT id, first_name, email FROM cars_reservation"
        ." WHERE MONTH(birth_day) BETWEEN '$m1' AND '$m2'"
        ." AND DAY(birth_day) BETWEEN '$d1' AND '$d2'";
        ." LIMIT $pgoffset,$limit";

    $result_item = $this->db->query($query_string);

    return $result_item->result();
}
