Are session variables considered cookies in PHP and do they require notification to users?

Session variables in PHP are not considered cookies, as they are stored on the server-side rather than on the client-side. Therefore, they do not require notification to users like cookies do. Session variables are used to store information that persists across multiple pages during a user's visit to a website. To use session variables in PHP, you need to start a session using session_start() at the beginning of your script. 

<?php
// Start the session
session_start();

// Set a session variable
$_SESSION['username'] = 'JohnDoe';

// Retrieve the session variable
echo $_SESSION['username'];
?>
