    public function uid()
    {
        // Random value all sequences group
        $uuid = Str::uuid();
        echo $uuid."<br>";
 
        // The result with order first sequence group
        $order1 = Str::orderedUuid();
        echo $order1."<br>";

        $order2 = Str::orderedUuid();
        echo $order2."<br>";
    }
}

Example #2 - UUID Using 3rd Party Package

We also can use 3rd party liabrary to generate UUIDs, we will use composer package for generate uuid in Laravel. After installing you don't have to insert alias name in provider. With below command to generate UUID.

Install Package

Install Packagte webpatser/laravel-uuid composer package to your laravel project by following command:

composer require webpatser/laravel-uuid

After then we can try to generate UUID if it works.

<?php
 
namespace App\Http\Controllers;
 
use App\Http\Controllers\Controller;
 
class HomeController extends Controller
{

    public function index()
    {
        $uuid = Uuid::generate()->string
        dd($uuid);
    }
}
