The object-oriented programming is all about effective planning and design and interface plays the role of a blueprint; traits help objects to implement that blueprint. Going overboard with traits break that effectiveness.
Let us try to understand that point in the light of our selling application. Consider this code.

//iDeliveryParty.php
namespace MyInterface;

interface iDeliveryParty {
function get($product);
function post($review);
}
However, not every user may want to post a review. In that case, the traits will come to our help for not only implementing the interface but also enhance the re-usability of the code.
