Question

What are traits in Laravel?

Answer 1

PHP Traits are simply a group of methods that you want include within another class. A Trait, like an abstract class cannot be instantiated by itself.Trait are created to reduce the limitations of single inheritance in PHP by enabling a developer to reuse sets of methods freely in several independent classes living in different class hierarchies.

Here is an example of trait.

trait Sharable {
 
  public function share($item)
  {
    return 'share this item';
  }
 
}

You could then include this Trait within other classes like this:

class Post {
 
  use Sharable;
 
}
 
class Comment {
 
  use Sharable;
 
}

Now if you were to create new objects out of these classes you would find that they both have the share() method available:

$post = new Post;
echo $post->share(''); // 'share this item' 
 
$comment = new Comment;
echo $comment->share(''); // 'share this item'
