这是我的多用户统计的在线统计部分

gb_temp表:
temp1 用户ID
temp2 流览IP地址  
temp3 online//做了个标记,因为其他功能也要使用这个表
temp4 登陆时间

$onlinetime最长离线时间分钟
db_class是我定义的一个数据库操作类。

///////////////////
//在线统计
$db = new db_class;
$db->connect();

$limit_time = time() - ($onlinetime * 60);
$online_time = time();

$db->query("delete from gb_temp where (temp4$db->query("insert into gb_temp (temp1,temp2,temp3,temp4) values ('$id','$ip','online','$online_time')");
$onres = $db->query("select count(*) from gb_temp where temp1='$id' and temp3='online'");
$onlineuser = $db->fetch_array($onres);
$onlineuser = $onlineuser[0];
