How can session values be updated in PHP without the need to log out and log back in?

To update session values in PHP without the need to log out and log back in, you can simply assign new values to the session variables directly. This can be done by accessing the $_SESSION superglobal array and updating the specific session variable with the new value. 

<?php
session_start();

// Update session value
$_SESSION['username'] = 'new_username';

// Access updated session value
echo $_SESSION['username'];
?>
