How can differences in server environments impact the functionality of PHP scripts related to cookies?

Differences in server environments can impact the functionality of PHP scripts related to cookies due to variations in server configurations, PHP versions, and security settings. To ensure consistent cookie functionality across different server environments, it is important to set the cookie parameters correctly and handle any potential errors or inconsistencies in a robust manner.

// Set cookie with secure and HttpOnly flags
setcookie('cookie_name', 'cookie_value', time() + 3600, '/', '', true, true);
