We will walk you through the process of creating UUIDs in Laravel 10 in this article. We will look at various ways and packages that make it easier to generate UUIDs and integrate them into the database structure of your application.

Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

What is UUID?

A UUID is a standardised identification that is intended to be unique throughout all space and time. It is a 128-bit value that is commonly expressed as a hexadecimal sequence separated by hyphens.

UUIDs are extensively used in computer systems and software to identify diverse items such as files, database records, network devices, software components, and others. They serve to reduce the likelihood of duplication, making them useful for a wide range of applications where uniqueness is required.

Generate UUID Using Str

We will use Str class to generate UUID.

Consider this example with a controller file say CustomController.php

<?php
 
namespace App\Http\Controllers;
 
use App\Http\Controllers\Controller;
use Illuminate\Support\Str;
 
class CustomController extends Controller
{
    public function index()
    {
        $uuid = Str::uuid()->toString();

        dd($uuid);
    }
}

Concept

You can use toString() and uuid() methods of Str.

$uuid = Str::uuid()->toString();

OR

$uuid = (string) Str::uuid();

Output

93df0150-160a-11ed-a017-15fb2ac449ef

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

    }
}

How to Check a UUID is valid?

Laravel Str class provides a method i.e isUuid. You can use it to check a UUID is valid or not.

<?php
 
namespace App\Http\Controllers;
 
use App\Http\Controllers\Controller;
use Illuminate\Support\Str;

class CustomController extends Controller
{
    public function index()
    {
        $isUuid = Str::isUuid('a0a2a2d2-0b87-4a18-83f2-2529882be2de');

        dd($isUuid);
    }
}

Output
