How can the issue of cookies expiring prematurely be addressed in PHP?

Cookies can expire prematurely if the expiration time is not set correctly or if there are issues with the server's time settings. To address this issue in PHP, you can ensure that the expiration time is set accurately by calculating the correct timestamp for the cookie expiration. You can also check and adjust the server's time settings if necessary.

// Set cookie with correct expiration time
$expiryTime = time() + 3600; // 1 hour
setcookie("cookie_name", "cookie_value", $expiryTime, "/");
