What are the best practices for managing PHP session variables?

To manage PHP session variables effectively, it is important to follow best practices such as properly initializing sessions, securely storing and accessing session data, and properly destroying sessions when they are no longer needed. This helps to ensure the security and efficiency of your PHP applications. 

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

// Set session variables
$_SESSION['username'] = 'john_doe';
$_SESSION['email'] = 'john.doe@example.com';

// Access session variables
$username = $_SESSION['username'];
$email = $_SESSION['email'];

// Destroy the session when no longer needed
session_destroy();
?>
