Object interfaces allow you to create code which specifies which methods a class must implement, without having to define how these methods are implemented. Interfaces share a namespace with classes and traits, so they may not use the same name.

Interfaces allow you to specify what methods a class should implement. Interfaces make it easy to use a variety of different classes in the same way. When one or more classes use the same interface, it is referred to as "polymorphism". Interfaces are declared with the interface keyword:
Introduction to the PHP interface. An interface allows you to specify a contract that a class must implement. To define an interface, you use the interface keyword as follows: <?php interface MyInterface { //...} Code language: HTML, XML (xml) An interface consists of methods that contain no implementation.
In an Abstract Class, you can define how some methods work, where as in an Object Interface you can not. An Object Interface is essentually nothing but a list of function names that a class must define if the class implements that interface.
Interfaces are an important part of PHP OOP, and they play a crucial role in helping to ensure that your code is well organized, maintainable, and scalable. By using interfaces, you can define contracts for your code, enforce consistency, and promote reusability.
10 sty 2024 · In object-oriented programming, interfaces define contracts that classes can implement, ensuring they provide specific methods with defined signatures. In PHP, interfaces enhance code organization, enable polymorphism, and facilitate dependency injection, laying foundational practices for robust application design.
Object-Oriented programming is one of the most popular programming paradigms based on the concept of objects and classes. PHP OOP allows you to structure a complex application into a simpler and more maintainable structure.
