What is the use of interface interface in PHP? What should I pay attention to What is a PHP interface? Using interfaces (interface), you can specify which methods a class must implement, but you do not need to define the specifics of these

In the Java language, abstract classes and interface are the two mechanisms that support the definition of an abstraction class. It is the existence of these two mechanisms that gives Java a powerful object-oriented capability. Abstract class and

In an abstract class, you can include one or more abstract methods, but in an interface (interface), all methods must be abstract and cannot have a method body, which is more "abstract" than an abstract class.Interfaces are declared by using the
