When you look on google for PHP interview question, then you find this one (How to utilize t trait in PHP). Some of the best coding developers within our network share their top questions, answers, and tips so that a developer’s PHP knowledge and expertise can be tested. So, before knowing how to utilize Traits, you have to comprehend what is traits.

What a Trait

A trait  is like a theoretical class which can't be accelerated on its own (though it is often more than the interface).
A new feature of language in PHP 5.4 has been known as TRAITS. An attribute is a sort of Mixin in which it enables you to mix trait classes in the existing class. This means that you can reduce code duplication and addition benefits while maintaining a strategic distance from numerous heritage problems.
One trait is only a set of methods that you need to incorporate into another category. A specialty like an abstract class cannot be done immediately on its own.
You know that interviewer ask you various sorts of PHP interview question like:

Whenever you need multiple inheritance,then what you will use?

Answer: Wherever you need multiple inheritances, you can use trait there, which reduces the complexity and with multiple inheritances and mixes Attaches to explicit issues keeps away from.

I will discuss those features which are traits presented in PHP 5.4. The idea of attributes included some additional qualities in single legacy. In other words, there is nothing like a trait, yet there is a component for the reuse of code in a single-inheritance.

Why and How To Use Traits?

This PHP interview question is the core question of PHP traits and,  the fundamental concept code behind the trait is reusable. In the specialty language, the code seems very useful in terms of reusable that supports only a single legacy like PHP. Therefore, the primary purpose behind utilizing the attribute is to benefit from the advantages of any inheritance and alternate of code reusable.
The traits cannot be instantaneous like unique classes and interfaces which just override their techniques. We make this by utilizing the Trait keyword.

Examples Of Trait

Let’s see how to start with the trait:

File Name: hoo.php
<?php trait hoo { public function sayHello(){ return “Hello”; } public function sayWorld(){ return “World”; } } ?>
A trait is used in class using keyword. Let’s look at an example using trait:
File Name: car.php
<?php include(“hoo.php”); class Car{ // Using the Trait Here use hoo; } $obj = new Car; // Executing the method from trait $obj->sayHello(); //Hello $obj->sayWorld(); // World ?>

Explanation:
Note that we utilize the foo name as a trait in the bar class, and in this, we can utilize the foo keyword properties and properties with bar objects.
Generally, all interviewers ask you this PHP interview question in short, What is the role of the traits, then your answer is (for reuse codes). Developers can compose strategies that can be utilized in any number of classes, to keep up their code DRY and more.
If you need to utilize the trait in a class, you can use the “use” keyword. All the attributes of the trait are accessible in the classroom where it is used. Calling the  technique for a trait is similar to calling an instance method.

Conclusion:
The conclusion according to the Best Interview Question:-
Traits allow PHP developers to make cleaner, simpler,and progressively effective codes while enabling increasingly complex systems to be created and used.
They are not good; they are fantastic! Utilizing OPP, they open up another level of development techniques to OOP programmers, and I believe they are a sign of things coming in future PHP versions.
