Traits

In a single inheritance language such as PHP, we often feel that we could have extended another class to inherit some functionalities. For example, in our Car class, we have inherited all the generic vehicle functionalities and now we might be in need of adding some e-commerce functionalities. Again, the Motorcycle class might want to have such e-commerce functionalities. As e-commerce related methods do not belong to the Vehicle class, we need to think of an alternative approach to reuse such e-commerce behavior. Hence, when we need to add a group of behaviors to our objects, we group the behaviors in terms of methods with a trait and use the trait inside our classes. A trait is similar to a class but you can't instantiate it; rather, you can use traits inside classes. A trait can be used in a class context with the use keyword; for example, use TraitName.

Check out the following trait syntax:

trait MyTraitName{
    function one()
  ...
