What are some best practices for beginners in PHP to ensure efficient management of cookie expiration based on user activity?

When managing cookie expiration based on user activity in PHP, beginners should consider setting a reasonable expiration time for the cookie based on the expected duration of user activity. Additionally, they should update the cookie expiration time whenever the user interacts with the website to ensure it remains valid. This can help prevent premature expiration of the cookie and provide a seamless user experience. 

// Set initial cookie expiration time
$expiration_time = time() + 3600; // 1 hour

// Check if user activity has occurred and update cookie expiration time
if (/* user activity condition */) {
    $expiration_time = time() + 3600; // Update expiration time to 1 hour from current time
}

// Set the cookie with the updated expiration time
setcookie("user_cookie", "value", $expiration_time, "/");
