    <html>
    <br />
    <?
    echo $_SESSION['start'];
    ?>
    <br />
    <?
    echo $_SESSION['expire'];
    ?>
    Welcome <?php echo $_SESSION['luser'];

    ?>
    </html>

  <?php
  }
}
?>

欢迎
这里有两个文件login.php和home.php，当用户成功登录会话时，使用该登录时间启动，会话在5分钟后超时。

它从登录时间开始计算时间，但现在我想用空闲会话超时来更改此会话。

当用户对主页不执行任何操作时，应将其销毁会话应将其销毁，我需要对此进行更改。感谢高级…

一旦页面呈现，PHP就完成了。要做到这一点，您需要客户端语言

可能最合理的方法是使用PHP将expire值导出到JavaScript变量中，然后设置一个间隔侦听器，该侦听器将检查过期时间是否小于现在，如果小于现在，则向用户发出警报

如果您仍然想使用PHP来实现这一点（破坏会话、与数据库通信等），唯一的方法是进行AJAX调用，您仍然可以通过JavaScript进行调用。用外行的话说，PHP一呈现页面就睡着了，您可以使用AJAX调用来唤醒它

既然你没有试图解决这个问题，我就不给你任何代码了。但是，我上面写的已经足够让你开始了
