You have just to follow the below step and you will get the layout as below:

Step 1: Install Laravel

This is optional; however, if you have not created the laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app
Step 2: Create Format Route web.php
<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\FindByValueController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/index',[FindByValueController::class, 'index']);
Step 3: create FindByValueController

we will create FindByValueController. so you can see the below code with output:

php artisan make:controller FindByValueController
App\Http\Controllers\FindByValueController
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FindByValueController extends Controller
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
    */
    public function index()
    {
        $collection = collect(['Doe',"John" ,"Gadas" ,"Maxy"]);
            
        dd($collection->search(function($item, $key) {
            
            $value = "John";

            return $item == $value;
        
        }));

    }
}
Step 4: Start Development Server

Start the development server. Use the PHP artisan serve command and start your server:

php artisan serve

Now you are ready to run our example so run the below command to quick run.

http://localhost:8000/index
Output:
