I am currently working on a PHP application and I'm facing some difficulties in handling errors related to user role or permission validation. The main issue is that I need to ensure that only specific users with the appropriate roles or permissions can access certain parts of the application.
I have implemented a user authentication system where each user has a specific role assigned to them. However, when a user tries to access a restricted area, I'm not quite sure how to handle the error gracefully.
Instead of simply displaying a bland "Access Denied" message, I would like to provide more helpful information to the user, such as their current role and the required role to access that particular area. This way, they can understand why they are being denied access and possibly take the necessary steps to obtain the required permissions.
So, my question is: How can I effectively handle these errors related to user role and permission validation in my PHP application? Are there any best practices or recommended approaches that I should follow? I would greatly appreciate any insights or examples that you can provide.
Thanks in advance for your help!
