if(haveAccessToEntity('adminPanel', $currentUser)) { // allow access to admin panel } else { // redirect user to login page }In this example, the `haveAccessToEntity` function is used to determine if the current user has permission to access the admin panel. If they do, they are allowed access, otherwise, they are redirected to the login page. This feature is often included in package libraries such as Laravel, Symfony, and Zend Framework.
