Today is an auspicious day because we are going to learn about Laravel 7 Traits, how to create Trait in Laravel, and how to use Trait in the Laravel 7 application. Traits allow us to develop a reusable piece of code and inject it in controller and modal in a Laravel application.

I will take the holistic approach that helps you understand the Laravel Traits topic with persistence and help you comprehend the correct usage of Traits in Laravel.
What are Traits?
In general, Traits are nothing but a reusable collection of methods and functions that can be incorporated in any other classes. Let’s see what the exact memoir of Traits as per PHP.
“Traits are a mechanism for code reuse in single inheritance languages such as PHP. A Trait is designed to lessen some limitations of single inheritance by permitting a developer to reuse sets of methods unobstructedly in numerous independent classes living in distinct class hierarchies. The semantics of the combination of Traits and classes is determined in a way which decreases complexity and bypasses the usual difficulties connected with compound inheritance and Mixins.
A Trait is comparable to a class, although only designed to group functionality in a fine-grained and constant way. It is not possible to instantiate a Trait on its own. It is an addition to traditional inheritance and enables horizontal composition of behaviour; that is, the application of class members without requiring inheritance.”
