How can PHP session settings impact the functionality of cookies in a script?

PHP session settings can impact the functionality of cookies in a script by controlling how sessions are managed and how session data is stored. If the session settings are not configured correctly, it can lead to issues with setting or retrieving cookies, which are often used to store session identifiers. To ensure proper functionality, make sure that the session settings are configured appropriately, including setting the correct path, domain, and secure settings for cookies. 

// Example of setting session settings to ensure proper cookie functionality
session_set_cookie_params([
    'lifetime' => 3600, // Set cookie lifetime to 1 hour
    'path' => '/', // Set cookie path to root
    'domain' => 'example.com', // Set cookie domain
    'secure' => true, // Use secure connection for cookie
    'httponly' => true // Prevent access to cookie through JavaScript
]);

session_start();
