How can one ensure that when a user closes their browser or navigates to a different website, the cookie is deleted along with the session in PHP?

To ensure that a cookie is deleted along with the session when a user closes their browser or navigates to a different website in PHP, you can set the cookie with a session-only expiration time. This way, the cookie will be deleted when the browser session ends. Additionally, you can use session_unset() and session_destroy() functions to remove the session data. 

// Start the session
session_start();

// Set a cookie with session-only expiration
setcookie("cookie_name", "cookie_value", 0, "/");

// Remove session data
session_unset();
session_destroy();
