Article Introduction：How to Create Reusable PHP Classes Using Inheritance Inheritance is an important concept in object-oriented programming that allows us to create a class that inherits the properties and methods of another class. Through inheritance, we can create reusable code, improve code reusability, and save development time. This article explains how to use inheritance to create reusable PHP classes and illustrates it with code examples. Parent class and subclass In inheritance, we usually have a parent class and one or more subclasses. The parent class usually contains some shared properties and methods, and the subclass inherits

Article Introduction：Definition and application of abstract methods of PHP classes In PHP object-oriented programming, abstract classes and abstract methods are very important concepts. Abstract classes are classes that cannot be instantiated and can only be inherited, while abstract methods are methods that are defined in abstract classes but not implemented concretely and must be implemented in subclasses before they can be used. This article will introduce in detail the definition and application of abstract methods in PHP, and provide specific code examples for readers to better understand. The definition of abstract methods in PHP is to define abstract methods by adding the abstract keyword in front of the method.

Article Introduction：Function inheritance allows derived classes to reuse the function definitions of the base class, which is achieved through the following steps: Define an abstract base class that contains pure virtual functions. Use the override keyword in the derived class to inherit and implement the functions of the base class. Practical case: Create the abstract base class Shape, and derive the classes Circle and Rectangle to calculate the areas of different shapes.

Article Introduction：How to use polymorphism and inheritance to handle data types in PHP Introduction: In PHP, polymorphism and inheritance are two important object-oriented programming (OOP) concepts. By using polymorphism and inheritance, we can handle different data types more flexibly. This article will introduce how to use polymorphism and inheritance to deal with data types in PHP, and show their practical application through code examples. 1. The basic concept of inheritance Inheritance is an important concept in object-oriented programming. It allows us to create a class that can inherit the properties and methods of the parent class.

Article Introduction：Before introducing the interface, we need to know why we need to use the interface. Here we will introduce it to you. Among computer languages, only a few object-oriented ones support multiple inheritance. The PHP language we are learning, like most languages, does not support multiple inheritance. To put it bluntly, a parent class can have multiple subclasses, but a subclass can only have one parent class. What is multiple inheritance? It is a subclass that inherits two or more parent classes. This is multiple inheritance, which is not allowed in PHP. If we want to implement multiple inheritance in PHP, then we have to use interfaces. Interfaces can be seen as a solution to multiple inheritance. PHP's object-oriented interface is similar to other object-oriented language interfaces.
