function checkOnline($userid,$tempid=null)
{
$conn = connect();
//对于所有用户
//先设置自己为在线
$stmt = "UPDATE ".DB_NAME.".USER SET IsOnline='Y' WHERE UserID=".$userid;
$result = query($stmt,$conn);
//info($stmt);
//如果当前用户是游客
if ($tempid != null)
{
$stmt = "SELECT TempID FROM ".DB_NAME.".TEMPUSER WHERE
TempID=".$tempid;
$result = query($stmt,$conn);
//info($stmt);
//如果该游客还在线
if ($row = fetch_array($result))
{
$stmt = "UPDATE ".DB_NAME.".TEMPUSER SET
RequestTime='".getCurrentTime()."' WHERE TempID=".$tempid;
$result = query($stmt,$conn);
//info($stmt);
}
//该游客已经离线
else
{
$stmt = "INSERT INTO ".DB_NAME.".TEMPUSER
VALUES('".$tempid."','".getCurrentTime()."')";
$result = query($stmt,$conn);
//info($stmt);
}
}
//查看其他用户
//普通用户
$stmt = "UPDATE ".DB_NAME.".USER SET IsOnline='N' WHERE ".time()." -
unix_timestamp(RequestTime) > ".ONLINE_DURATION." AND UserGroupID != ".GUEST;
$result = query($stmt,$conn);
//游客
$stmt = "DELETE FROM ".DB_NAME.".TEMPUSER WHERE ".time()." -
unix_timestamp(RequestTime) > ".ONLINE_DURATION;
$result = query($stmt,$conn);
disconnect($conn);
}
//得到在线人数，分用户和游客
function getOnlineNumber()
