Traits allow you to declare methods that can be used in multiple classes. It means if you declare a method in the trait, you can use it in multiple classes.
The static method can be directly called through Scope Resolution Operator (::), which means there is no need to create an instance of the class.
The interface allows you to declare public methods that a class should implement. It means, when you implement an Interface into a class then it has to implement all the methods that are declared in the Interface.
Abstract classes are a powerful concept in object-oriented programming. They are used to define abstract representational and behavioral combinations, which means they cannot be instantiated without being subclassed.
