How can a PHP developer ensure that the state of a hidden element, controlled by JavaScript and session cookies, persists until the browser is closed?

To ensure that the state of a hidden element, controlled by JavaScript and session cookies, persists until the browser is closed, the PHP developer can set the cookie expiration time to 0, which means the cookie will be deleted when the browser is closed. This way, the hidden element's state will be retained as long as the browser session is active.

// Set session cookie with expiration time of 0
setcookie("cookie_name", "cookie_value", 0);
