对id的处理用字符串查找来处理,这样的方式其实不太合理。
- PHP code
define('MAX_ITEMS', 5);$id = intval($_GET['id']); // 确保id是整数if (isset($_COOKIE['recentlyGoods'])) { // 已有历史数据,追加新数据 $goods = explode(',', $_COOKIE['recentlyGoods']); // 取得id数组 $key = array_search($id, $goods); // 在历史数据中查找当前id if ($key !== false) { unset($goods[$key]); // 找到则删除 } $goods[] = $id; // 追加当前浏览的id} else { // 尚未有历史数据,创建并将当前浏览id加入 $goods = array($id);}// 如果数组中历史数据条目超出限制,则截取最后一段if (count($goods) > MAX_ITEMS) { // 从倒数第MAX_ITEMS条开始提取MAX_ITEMS条记录 $goods = array_slice($goods, 0 - MAX_ITEMS, MAX_ITEMS);}setcookie('recentlyGoods', join(',', $goods), time()+3600);<div class="clear"> </div>
