What Is Polymorphism?

Polymorphism allows objects to have multiple forms. In PHP, it means that a method can behave differently depending on the object that is calling it. This is achieved through method overriding or interface implementation.

Key Point: Polymorphism simplifies code and enhances flexibility by allowing the same method to perform different tasks depending on the context.
