How can session cookies impact the behavior of PHP scripts?

Session cookies can impact the behavior of PHP scripts by storing session identifiers in the user's browser. If the session cookie is not properly secured, it can be vulnerable to session hijacking or manipulation. To mitigate this risk, developers should ensure that session cookies are secure by setting the 'secure' and 'httponly' flags in the cookie parameters.

// Set session cookie parameters to secure and httponly
session_set_cookie_params([
    'lifetime' => 0,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,
    'httponly' => true
]);
