What is the best practice for maintaining session variables in PHP without resetting the session timeout?

When working with session variables in PHP, it is important to ensure that the session timeout is not reset each time a session variable is accessed or modified. One way to maintain session variables without resetting the session timeout is to call session_write_close() after setting or updating session variables. This function closes the session file, allowing other scripts to access the session data without affecting the session timeout. 

<?php
session_start();

// Set or update session variables
$_SESSION['username'] = 'john_doe';

// Close the session file to prevent resetting the session timeout
session_write_close();

// Continue with the rest of your code
?>
