What are the methods for implementing user authorization in Slim Framework?

Answer: In the Slim Framework, user authorization can be implemented using the following methods:

1. Middleware: Create middleware to check user permissions before accessing specific routes. This can validate user roles or capabilities.

2. Session Management: Use PHP sessions to store user authentication status and roles, allowing for checks on each request.

3. JWT (JSON Web Tokens): Implement JWT for token-based user authentication, allowing users to authorize API requests securely.

4. OAuth2: Integrate OAuth2 for third-party authentication and authorization, enabling users to log in using social platforms.

5. Custom Authorization Logic: Write custom logic in controllers or services that checks user permissions based on predefined rules.

6. Third-Party Libraries: Use libraries like `PHP-Auth` or `Spiffy` for more robust user authentication and authorization features.

These methods can be combined for enhanced security and flexibility depending on the application’s needs.
