What are some best practices for managing sessions in PHP forms to ensure smooth functionality?

When managing sessions in PHP forms, it is important to ensure smooth functionality by properly starting, storing, and destroying session data. To do this, always start the session at the beginning of your PHP script, store form data in session variables for persistence across multiple pages, and remember to destroy the session once it is no longer needed to free up server resources. 

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

// Store form data in session variables
$_SESSION['username'] = $_POST['username'];
$_SESSION['email'] = $_POST['email'];

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