WHAT IS interface in Magento?
A public interface is a set of code that third-party developers can call, implement, or build as a plug-in.

What are interfaces in PHP?
A PHP interface defines a contract which a class must fulfill. If a PHP class is a blueprint for objects, an interface is a blueprint for classes. Any class implementing a given interface can be expected to have the same behavior in terms of what can be called, how it can be called, and what will be returned.
How do you define an interface?
An interface is declared by using the interface keyword. It provides total abstraction; means all the methods in an interface are declared with the empty body, and all the fields are public, static and final by default. A class that implements an interface must implement all the methods declared in the interface.
How do we declare an interface class?

WHAT IS interface and its use?
You use an interface to define a protocol of behavior that can be implemented by any class anywhere in the class hierarchy. Interfaces are useful for the following: Declaring methods that one or more classes are expected to implement. Revealing an object’s programming interface without revealing its class.
Can PHP interface have properties?
