I am able to get my (current user) login date and time. But I don't have an idea how can I get previous user(Admin) login and logout date/time detail.

I am sending my login.php code.Where i wrote current user time/date code.Please see the code and give me suggestion how can i get previous user login and logout date/time. Thanks.

Answer 1

I can give you the basic logic for this. In this you can set the session variable that it will act as flag.

// 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

You can insert the user id, date and time at the time of login and get it back as last id that will be your previous login.

Answer 2

Create one activity table in database. Click the link to view example here-> User Activity Table Structure

Every time when any user logs in, just enter the login time and user id along with other required details in the activity table. At the time of login you can change the login status to deactivated for that particular session. Next time when any user logs in you can get the last login time from database and current time from PHP date() function. Just get the time difference between those 2 dates and you will get the last login time and duration by previous user. That's it.

Hope this would work.
