php trait



les traits sont un mécanisme de réutilisation de code dans un langage à héritage simple tel que php. un trait tente de réduire certaines limites de l'héritage simple, en autorisant le développeur à réutiliser un certain nombre de méthodes dans des classes indépendantes. la sémantique entre les classes et les traits réduit  depuis sa version ., php intègre un moyen de réutiliser le code d'une méthode dans deux classes indépendantes. cette fonctionnalité permet ainsi de repousser les limites de l'héritage simple (pour rappel, en php, une classe ne peut hériter que d'une seule classe mère). nous allons donc nous  depuis php .., php supporte une nouvelle manière de rendre le code plus réutilisable : les traits. le principe des traits est de permettre de contourner les limites imposées par l'héritage simple de php. le but est de permettre de créer de nouvelles méthodes et de nouvelles propriétés que l'on pourra ajouter à nos

one of the problems of php as a programming language is the fact that you can only have single inheritance. this means a class can only inherit from one other class. however, a lot of the time it would be beneficial to inherit from multiple classes. for example, it might be desirable to inherit methods from a  an interface defines a set of methods that the implementing class must implement. when a trait is use 'd the implementations of the methods come along toowhich doesn't happen in an interface . that is the biggest difference. from the horizontal reuse for php rfc: traits is a mechanism for code reuse  in this tutorial, you will learn how to use php traits to share functionality across independent classes, which are not in the same inheritance hierarchy.

in this article i will discuss traits, a new feature introduced in php . to overcome such issues. the concept of traits itself is nothing new to programming and is used in other languages like scala and perl. they allows us to horizontally reuse code across independent classes in different class hierarchies. php traits provide a convenient means of sharing methods between classes. there are times though that we may need to override or extend a method defined in a trait attached to a class. let's take a look at how we can achieve this. let's start by defining a very simple trait as an example called footrait  it's another quick primer this time. today we're going to talk about a php . feature called traits. while laravel doesn't make heavy use of traits they are sprinkled around the core codebase, so you'll want to get familiar with them. if you are new to php or even if you are a veteran php programmer you may have heard about traits but don't quite know what they do or why they are neededwell, luckily they are much easier than you would think and it only takes seconds to grasp the concept.so, what are these so called tra
