What are common pitfalls when using sessions in PHP, and how can they lead to the constant restarting of sessions?

Common pitfalls when using sessions in PHP include not calling session_start() at the beginning of each page that needs to access session variables, not properly setting session variables, and not properly destroying sessions when they are no longer needed. These issues can lead to the constant restarting of sessions and loss of session data. 

<?php
session_start();

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

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