    What are Traits?

    Traits are simply the way to share methods among classes in your application while keeping an equal eye on DRYing up code and making sure its re-usability in the application.

    In this article, we’ll go through the problem and then look at how using Traits can solve it for us.

    User Classes

    Let’s assume, we want to create an admin panel along side the basic users functionality as well. So basically, we would have a couple of classes to start with.

    class User {
    
    }
    
    class Admin {
    
    }

    These classes might share a couple of methods but on the same side might not share all of them. To tackle this type of problem, we’ll create a Trait like so

    trait Authenticatable {
    
    //List of Methods
    
    }

    And to use methods from this Trait, we’ll simple use the use keyword,

    class User {
    
        use Authenticatable;
    
    }

    Well that’s it. Its this simple to DRY up your application’s code-base using traits.

    Final Words

    Traits are important part of PHP application as PHP doesn’t support multiple inheritances. Traits comes to the rescue and lets you share methods between classes with ease.
