Protected classes in Laravel are used to encapsulate common functionality and behavior that can be reused by other classes. This can help to improve code organization and readability, and to reduce duplication of effort.

Benefits of using Protected class

• To implement authentication and authorization logic. This can be done by creating a protected base class that defines the common functionality, and then creating child classes for specific authentication and authorization providers.
• To implement common database operations. For example, you could create a protected base class that provides methods for creating, reading, updating, and deleting database records. Child classes could then be created to implement specific database operations for different types of models.
• To implement common business logic. For example, you could create a protected base class that provides methods for calculating shipping costs or generating invoices. Child classes could then be created to implement the specific business logic for different types of products or services.

Why use protected class instead of private class in Laravel?

The main difference between protected and private classes is that protected classes are accessible to child classes, while private classes are not. This means that protected classes can be used to implement common functionality and behavior that can be reused by other classes, while private classes are typically used to encapsulate sensitive data and logic.

In general, you should use protected classes whenever you need to implement common functionality and behavior that can be reused by other classes. You should only use private classes when you need to encapsulate sensitive data and logic.

Protected classes are a powerful tool that can be used to improve the organization, readability, security, and reusability of your Laravel code.
