I will give you simple following three examples:

2) Laravel Collection Add Attribute using map()

3) Laravel Eloquent Collection Add Attribute using map()

Let's see the below examples:

Example 1: Laravel Eloquent Collection Add Attribute using setAttribute()

app/Http/Controllers/DemoController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\User;
  
class DemoController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $user = User::first();
  
        $user->setAttribute('position', 'Web Developer');
  
        dd($user->toArray());
    }
}

Output:

array:8 [
  "id" => 1
  "name" => "Hardik Savani"
  "email" => "aatmaninfotech@gmail.com"
  "email_verified_at" => null
  "created_at" => "2022-05-23T12:58:18.000000Z"
  "updated_at" => "2022-05-23T12:58:18.000000Z"
  "birthdate" => "2001-05-23"
  "position" => "Web Developer"
]

Example 2: Laravel Collection Add Attribute using map()

app/Http/Controllers/DemoController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use Illuminate\Support\Str;
  
class DemoController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $posts = collect([
            ['id'=>1,'title'=>'Post One'],
            ['id'=>2,'title'=>'Post Two'],
            ['id'=>3,'title'=>'Post Three'],
            ['id'=>4,'title'=>'Post Four'],
        ]);
   
        $posts = $posts->map(function ($post) {
            $post['url'] = url("post/". Str::slug($post['title']));
            return $post;
        });
  
        dd($posts->toArray());
    }
}

Output:

Array
(
    [0] => Array
        (
            [id] => 1
            [title] => Post One
            [url] => http://localhost:8000/post/post-one
        )
    [1] => Array
        (
            [id] => 2
            [title] => Post Two
            [url] => http://localhost:8000/post/post-two
        )
    [2] => Array
        (
            [id] => 3
            [title] => Post Three
            [url] => http://localhost:8000/post/post-three
        )
    [3] => Array
        (
            [id] => 4
            [title] => Post Four
            [url] => http://localhost:8000/post/post-four
        )
)

Example 3: Laravel Eloquent Collection Add Attribute using map()

app/Http/Controllers/DemoController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\Post;
  
class DemoController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $posts = Post::select("id", "title", "status")->take(5)->get();
  
        $posts = $posts->map(function ($post) {
            $post->status_label = $post->status == 1 ? 'Active' : 'InActive';
            return $post;
        });
  
        dd($posts->toArray());
    }
}

Output:

Array
(
    [0] => Array
        (
            [id] => 2
            [title] => Demo Updated
            [status] => 1
            [status_label] => Active
        )
    [1] => Array

            [id] => 3
            [title] => Dr.
            [status] => 0
            [status_label] => InActive
        )
    [2] => Array
        (
            [id] => 4
            [title] => Miss
            [status] => 0
            [status_label] => InActive
