An Interface allows the users to create programs, specifying the public methods that a class must implement, without involving the complexities and details of how the particular methods are implemented. In the following example, we will show you how to use the interface to make the system easier to extend and more flexible. La classe implémentant l'interface doit utiliser des signatures de méthodes The class implementing the interface must use the exact same method signatures as are defined in the interface. PRIMARY PURPOSES OF AN INTERFACE: Interfaces allow you to define/create a common structure for your classes – to set a standard for objects. Interfaces are not quite the same as classes as the class can inherit from one class but the class can implement one or more interfaces.

Here we have declared three interfaces i.e 'interface a',' interface b', 'interface c'.In this case interface c also extends the previous two interfaces. Interface in PHP. When you create a class that you want to implement that interface, you simply declare the class, as you would normally would and follow that line with implements name_of_interface. In the case of interface parent-child relationship does not exist. Once upon a time, there was a web developer who used to spend weeks and weeks updating the same lines of code. It allows us to have assurance that any given dependency … PHP Interface will only define arguments and names rather than the contents of the methods and any class which implements the interface need to implement all the methods which are defined by the interface. In case you would want to, a child class can implement an interface: Solution for overriding interface constants, //I am from interface 1 \n I am from test class. Les constantes d'interfaces fonctionnent exactement due to trickery one needs to do to work around lack of multiple inheritance), simply add  __construct() to your interface, so risk of init being forgotten is reduced. Les deux di… To two notes below: There is one situation where classes and interfaces can be used interchangeably. De la même manière que pour les classes abstraites, nous n’allons pas directement pouvoir instancier une interface mais devoir l’implémenter, c’est-à-dire créer des classes dérivées à partir de celle-ci pour pouvoir utiliser ses éléments. Interfaces solves the problem of single inheritance – they allow you to inject ‘qualities’ from multiple sources. Créer une interface Une interface se déclare avec le mot-clé interface, suivi du nom de l'interface, suivi d'une paire d'accolades. When you are sharing code with closely related objects, you use class abstraction. Interfaces allow you to specify what methods a class should implement. Let us see all about it, in detail with this article. When I first saw the word SOLID, as in someone referring to SOLID programming, I thought they meant it was solid, as in cool or legitimate. You can implement multiple Interfaces in one class. Dans le cas contraire, une erreur fatale sera émise. Any classes implementing an interface must implement all methods defined by the interface. When a class implements an interface, It means it contains same public methods of an interface with their implementation. PHP Interfaces: In PHP, the interface blocks which declares set of functions to be defined with a class to implement this interface. Exemple #3 Héritage de plusieurs interfaces, Exemple #4 Interfaces avec des constantes. Let' create an interface and implement it with a simple example. An interface comprises of methods that have no content, which means the interface methods are abstract methods. A TV interface for gaming or streaming is also included. Interfaces are one of the main features of object-oriented languages, they provide polymorphic behavior and are the base of highly extended patterns and techniques like the Repository Pattern and Dependency Injection, but do they really make sense in PHP?Let's dig into this. Introduction to PHP Interface. Interface Interfaces are used when you need to enforce a class to implement When we create an interface in an application, we define a contract for what a class can do, without saying anything about how the class will do it.

In PHP coding with object interfaces (as a keyword) and "interfaces" in the more general context of use that includes both object interfaces and abstract classes, the purpose of "loose binding" (loosely bound objects) for ease of change and re-use is a helpful way to think about both uses of the term "interface." Interface classes completely empty the shells while expecting child classes to implement everything for them. An interface is an outline of what a particular object can do. An interface contains no logic. Most developers know that they cannot use multiple inheritance in PHP. Any classes implementing an interface must implement all methods defined by the interface. In PHP, an interface can extend another interface and thereby it inherits all functions declared with this interface. The structure I am working with has a lot of inheritance going on, but not all methods are specified in one place.
