traits
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;
}
