復(fù)制代碼 代碼如下:

uid<int(10)> ：用戶id
session_id<varchar(40)> ：用戶登錄后系統(tǒng)產(chǎn)生的session_id，PHP可是使用session_id()函數(shù)獲取
login_time<int(10)> ：登錄時(shí)間
logout_time<int(10)> ：登出時(shí)間

復(fù)制代碼 代碼如下:

$uid = $_SESSION[uid] = $info[id];
$session_id = $_SESSION[session_id] = session_id();
$login_time = time();
$logout_time = time() 600;
$sql = "INSERT INTO member_login (uid,session_id,login_time,logout_time) values($uid,$session_id,$login_time,$logout_time)";
mysql_query($sql);

復(fù)制代碼 代碼如下:

if($_SESSION[uid]){
$uid = $_SESSION[uid];
$session_id = $_SESSION[session_id];
$logout_time = time() 600;
$sql = "UPDATE member_login SET logout_time=$logout_time WHERE uid=$uid AND session_id=$session_id";
mysql_query($sql);
}
