code: public function bindArray($param, $values, $type = null)
      {
        foreach ($values as $index => $value) {
          $this->bind($param.$index, $value, $type);
        }   
      }
docs: Iterates over an array binding each element.
  Giving it ":id" for the param would result in the bindings of:
  :id1,
  :id2,
  :id3, etc
