How can a PHP developer ensure that a user remains logged in even after closing their browser using session cookies?

To ensure that a user remains logged in even after closing their browser using session cookies, a PHP developer can set the session cookie expiration time to a longer period, such as several days or weeks. This way, the session cookie will persist even after the browser is closed, allowing the user to stay logged in for an extended period of time.

// Set session cookie expiration time to 1 week
ini_set('session.cookie_lifetime', 604800);

// Start the session
session_start();
