How to generate UUID in Laravel 5 ?

What is UUID?

Laravel package to generate and to validate a universally unique identifier (UUID) according to the RFC 4122 standard. Support for version 1, 3, 4 and 5 UUIDs are built-in.

Installation

In Laravel 5.5 laravel-uuid will install via the new package discovery feature so you only need to add the package to your composer.json file

composer require "webpatser/laravel-uuid:^3.0"

after installation, you should see

Discovered Package: webpatser/laravel-uuid

and you are ready to go 

Usage

To quickly generate a UUID just do

Uuid::generate()

This will generate a version 1 Uuid object with a random generated MAC address.

To echo out the generated UUID, cast it to a string

(string) Uuid::generate()

or

Uuid::generate()->string

Advanced Usage

UUID creation

Generate a version 1, time-based, UUID. You can set the optional node to the MAC address. If not supplied it will generate a random MAC address.

Uuid::generate(1,'00:11:22:33:44:55');

Generate a version 3, name-based using MD5 hashing, UUID

Uuid::generate(3,'test', Uuid::NS_DNS);

Generate a version 4, truly random, UUID

Uuid::generate(4);

Generate a version 5, name-based using SHA-1 hashing, UUID

Uuid::generate(5,'test', Uuid::NS_DNS);

Some magic features

To import a UUID

$uuid = Uuid::import('d3d29d70-1d25-11e3-8591-034165a3a613');

Extract the time for a time-based UUID (version 1)

$uuid = Uuid::generate(1);
dd($uuid->time);

Extract the version of an UUID

$uuid = Uuid::generate(4);
dd($uuid->version);
