Course Introduction：Abstract classes and methods are used in PHP to build object-oriented programming structures that define the blueprints that other classes must follow. Abstract classes cannot be instantiated directly, they can only be inherited, and can contain ordinary methods and abstract methods; abstract methods only define method names and parameters, and there is no concrete implementation. Subclasses must implement all abstract methods. Use abstract classes to force consistency, avoid duplicate code and optimize design. For example, the payment method class can define an abstract process() method, and different payment types can be implemented on demand. Key rules include: classes containing abstract methods must be declared as abstract classes, abstract classes cannot coexist with finals, and interfaces are stricter and have no implementation.

Course Introduction：Creating and using classes in ES6 is very intuitive. It introduces the class keyword to define templates for objects, making JavaScript's object-oriented programming closer to other languages ??(such as Java or Python). Although it is still a syntactic sugar based on prototypes in nature, it is clearer and easier to maintain. Here are some key points and usages that you really need to master. 1.

Course Introduction：PHP has perfect support for object-oriented programming. Classes are templates for objects, objects are instances of classes, and namespaces are the ultimate solution to naming conflicts for global members. Starting from PHP5.3, the emergence of namespaces, and PHP.5.4, the Trait class breaks through the limitations of single inheritance, making the functions of the class more flexible.
