通过动作时间,如果动作时间超时便踢出!使用mktime是个很好的时间计算函数
可以方便的计算时间差。最小单位是秒。

函数

function user_mktime($onlinetime){
    $new_time = mktime();
        echo $new_time-$onlinetime;
    if($new_time-$onlinetime > 100){
        echo "登录超时";
        session_destroy();
    }else{
        $_SESSION[times]=mktime();
    }
}
?>
