What are common mistakes made when working with PHP sessions?

Common mistakes when working with PHP sessions include not starting the session before using any session variables, not properly destroying the session when it is no longer needed, and not properly securing the session data to prevent unauthorized access. To solve these issues, always start the session with session_start() at the beginning of your PHP script, use session_destroy() to properly destroy the session when it is no longer needed, and make sure to set session variables securely using session_regenerate_id() and session_set_cookie_params(). 

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

// Set session variables securely
session_regenerate_id(true);
session_set_cookie_params(0, '/', '.yourdomain.com', true, true);

// Use session variables as needed

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