What did you thinks about this another syntax ?

        $data = array();
        foreach ($list as $tag) {
            $data[] = array(
                'id_tag' => (int)$tag,
                'id_product' => (int)$id_product,
                'id_lang' => (int)$id_lang
            );
        }
        $result = Db::getInstance()->insert('product_tag', $data);

If $data is empty, Db::insert() return true, maybe this can be more readable ?
