What are common issues with PHP sessions and cookies when using frames?

When using frames in PHP, common issues with sessions and cookies arise due to the way frames handle requests. To solve this, you can set the session cookie parameters to be accessible across all frames by specifying the `SameSite=None` attribute and `Secure` attribute if the site is served over HTTPS. 

// Set session cookie parameters for cross-frame compatibility
session_set_cookie_params([
    'samesite' => 'None',
    'secure' => true,
    'httponly' => true
]);
