How can server settings impact the functionality of PHP scripts, specifically in relation to login processes?

Server settings such as session handling, cookie settings, and security configurations can impact the functionality of PHP scripts, especially in relation to login processes. To ensure smooth login functionality, it is important to configure these server settings properly to allow for secure and efficient user authentication.

// Example code snippet for setting session cookie parameters for login functionality
session_set_cookie_params([
    'lifetime' => 3600,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,
    'httponly' => true
]);
session_start();
