What are the differences between Interfaces and Abstract Classes in PHP?
Article Introduction：In PHP, the difference between interfaces and abstract classes is mainly reflected in the definition, inheritance model and implementation method. 1. The interface only defines method signatures (PHP8.1 supports default methods), emphasizing "what should be done", while abstract classes can contain abstract methods and concrete implementations, emphasizing "how to implement some functions". 2. Classes can implement multiple interfaces, but can only inherit one abstract class, so interfaces are more flexible when combining multiple behaviors. 3. The interface method is exposed by default and cannot have attributes. Abstract classes support arbitrary access control, attributes, constructors and destructors. 4. Use interfaces when a unified API is required or when an interchangeable component is designed; use abstract classes when a shared state or logically related classes. The selection basis is: the interface is used to define the contract, and the abstract class is used to share the implementation logic.
