Why is it important to include session_start() before using session_destroy()?

When using session_destroy() in PHP to end a session, it is important to include session_start() before it because session_destroy() will only work if a session has been started. By calling session_start() before session_destroy(), you ensure that the session is initialized and can then be properly destroyed. 

<?php
session_start();
session_destroy();
?>
