这篇文章主要介绍了php+memcache实现的网站在线人数统计代码,代码例子简洁实用,需要的朋友可以参考下

今天闲来无事,想在博客统计中显示在线人数。在网上找了好多例子,不是数据库存储数据就是文件存储,代码也看起来过于复杂。

晚上回来后,构思了下,看到我服务器中安装有 Memcache 服务,,何不用 Memcache 实现呢。

下面就来讲下实现过程:

效果图:

实现代码:

connect ( "127.0.0.1", 11211 ); // 获取 在线用户 IP 和 在线时间数据 $online_members = $mc->get ( 'online_members' ); // 如果为空,初始化数据 if (! $online_members) { $online_members = array (); } // 获取用户ip $ip = $_SERVER ["REMOTE_ADDR"]; // 为访问用户重新设置在线时间 $online_members [$ip] = time (); foreach ($online_members as $k => $v) { // 如果三分钟后再未访问页面,刚视为过期 if (time() - $v > 180) { unset($online_members[$k]); } } // 重新设置在线用户数据 $mc->set ( 'online_members', $online_members ); // 重新获取在线用户数据 $online_members = $mc->get ( 'online_members' ); // 输入统计在线人数 echo count($online_members); ?>
