1:What are traits ?

Traits are basically a peice of code where we reuse wherever we need it , like we need to save image in different controllers so what we do , we actually use move command and save the image , whcih results in repetive same code then we use traits. Hence traits are like objects where you can't direct call them , basically they are public protected functions which are mostly call by inside a function .
Here we are consider an example of api response.

For creating trait create a folder manually , traits inside app like this app/Traits and inside this traits make a file ApiResponse.php

As shown below we are using an API response for success() and error() method which sends the response in json format by calling them from controller , paste the following code in app/Traits/ ApiResponse.php
code for traits Copy

<?php

namespace App\Traits;

use Carbon\Carbon;

|--------------------------------------------------------------------------

| Api Responser Trait

|--------------------------------------------------------------------------

| This trait will be used for any response we sent to clients.

trait ApiResponse

{

/**

* Return a success JSON response.

* @param array|string $data

* @param string $message

* @param int|null $code

* @return \Illuminate\Http\JsonResponse

protected function success($data, string $message = null, int $code = 200)

{

return response()->json([

'status' => 'Success',

'message' => $message,

'data' => $data

], $code);

}

/**

* Return an error JSON response.

* @param string $message

* @param int $code

* @param array|string|null $data

* @return \Illuminate\Http\JsonResponse

protected function error(string $message = null, int $code, $data = null)

{

return response()->json([

'status' => 'Error',

'message' => $message,

'data' => $data

], $code);

}

use App\Models\Role;

use Hash;

use App\Traits\ApiResponse;

use Auth;

class DeveloperCorner extends Controller

{

use ApiResponse;

public function TestTraits()

{

$data = 'Developer Corner';

$message = 'Welcome to Developer Corner';

return $this->success($data,$message);

}
