如何获得最后登录管理时间和日期登录后我在php

Question

我有5管理员在数据库中。所以现在我想让最后一个用户登录日期和时间的细节。在我登录仪表板之后，谁工作过me.means，我想查看以前的USER登录和注销时间和日期。

我能得到我的（当前用户）登录的日期和时间。但我不知道如何获得以前的用户（Admin）登录和注销日期/时间详细信息。

我发送我的login.php代码。我写了当前用户时间/日期代码。请参阅代码并给我建议如何获得以前的用户登录和注销日期/时间。 谢谢。

<?php include "db.php"; ?>

} 
} 
header ("location: ../admin"); 
}else{ 
header ("location: ../index.php"); 
} 
?> 

所以经过我的仪表盘（的index.php）的页面，我没有附和变量，我可以看到当前用户登录登录日期/时间detail.Which是我的登录细节。

请给我建议，我怎样才能获得以前的用户登录和注销的细节。 感谢

这里IAM让管理员登录的日期和时间detail.But我无法获得先前的观众登录细节。在这里登录后，我只能看到我的登录时间/日期详细信息。 所以请帮助。

Answer 1

我可以给你的基本逻辑这一点。在这里你可以设置会作为标志的会话变量。

// start session 
session_start(); 

// if not yet logged in update database 
if(!isset($_SESSION['logged'])) 
{ 
    // update your database here 
    $query = "UPDATE table 
      SET LastLogin=now() 
      WHERE ID='$ID'"; 
    $result = mysql_query($query); // etc... 

    // if the table was updated 
    if($result === true) 
    { 
     // then create a session var 
     $_SESSION['logged'] = 1; 
    } 
} 

OR

您可以将在登录时的用户名，日期和时间，并把它早在最后一个ID，这将是你以前的登录。

Answer 2

在数据库中创建一个活动表。点击链接查看示例 - > User Activity Table Structure

每当有任何用户登录时，只需在活动表中输入登录时间和用户ID以及其他所需详细信息即可。在登录时，您可以将登录状态更改为取消激活该特定会话。 下一次，当你在任何用户登录可以从PHP从数据库中获得和当前时间的最后登录时间日期（）功能。只需获得这两个日期之间的时差，您将获得上一个用户的最后登录时间和持续时间。 就是这样。

希望这会起作用。
