What are properties and methods in PHP classes?

25 Jun 2025

The properties and methods of classes in PHP are the basis of object-oriented programming. Attributes are used to store the data of an object, such as $name and $email in $classUser; methods are used to define the behavior of an object, such as setName() and getName() are used to safely set and get property values. Best practices include: 1. Keep attributes private to avoid direct access; 2. Use getter and setter methods to control attribute operations; 3. Encapsulate related functions into methods; 4. Use type declarations to improve code robustness. Following these principles can improve the maintainability and reusability of your code.

What are abstract classes and methods in PHP?

20 Jun 2025

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.
