这篇文章主要介绍了用php代码限制国内IP访问我们网站,需要的朋友可以参考下
利用淘宝的IP接口来判断IP,是否是国内的ip,是国内(CN)的就不允许访问。
$ip = $_SERVER['REMOTE_ADDR']; $content = file_get_contents(‘?ip='.$ip); $banned = json_decode(trim($content), true); $lan = strtolower($_SERVER['HTTP_ACCEPT_LANGUAGE']); if((!empty($banned['data']['country_id']) && $banned['data']['country_id'] == ‘CN') || strstr($lan, ‘zh')) { header(“HTTP/1.0 404 Not Found”); echo ‘HTTP/1.0 404 Not Found'; exit; }
同时发现一篇好文章: 《Redis 来限制高并发 php代码实例》
Redis本质上也是一种键值数据库的,但它在保持键值数据库简单快捷特点的同时,又吸收了部分关系数据库的优点。从而使它的位置处于关系数据库和键值数据库之间。Redis不仅能保存Strings类型的数据,还能保存Lists类型(有序)和Sets类型(无序)的数据,而且还能完成排序(SORT) 等高级功能,在实现INCR,,SETNX等功能的时候,保证了其操作的原子性,除此以外,还支持主从复制等功能。
Redis 来限制高并发
php代码实例
$redis->setnx(‘lock:hot_items', true)尝试创建一个key作为”锁”.若key已存在,setnx不会做任何动作且返回值为false,所以只有一个客户端会返回true值进入if语句更新缓存. $redis = new redis(); $redis_key = ‘lock:hot_items'; $clock_expire_time = $redis->get($redis_key); if(!empty($clock_expire_time) && time() > intval($clock_expire_time)) { //解除当前Redis锁 $redis->delete($redis_key); } if($redis->setnx($redis_key, time() + 3) !== true) { echo ‘高并发有冲突'; } //操作你的代码, 同一时刻就一个人访问该代码了 //解除当前Redis锁 $redis->delete($redis_key);
