In this tutorial, we will how to apply automatic logout after 10 minutes of inactive session.
Step 1: Start a new session by using session_start() the function at the beginning of the script.
Step 2: Set a timer when the user logs in or accesses a page by setting a session variable with the current time, for $_SESSION[‘last_activity’] = time();
Step 3: On every page load, the system checks the difference between the current time and the last activity time. If the difference is greater than 10 Minutes(10*60 seconds), the user session will logout and redirect to the login page.
