About

Since Laravel 4.* and 5.* both rely on either OpenSSL or Mcrypt, the pseudo random byte generator now tries to use one of them. If both cannot be used (not a Laravel project?), the 'less random' mt_rand() function is used.

Requirements

Laravel 5.3, 5.4 or 5.5+

Installation

Laravel 5.5 and above

From your projects root folder in terminal run:

    composer require novay/laravel-uuid

Uses package auto discovery feature, no need to edit the config/app.php file.

Laravel 5.4 and below

From your projects root folder in terminal run:

    composer require novay/laravel-uuid:2.0

    'aliases' => [
        'Uuid' => Novay\Uuid\Uuid::class,
    ];

Basic Usage

To quickly generate a UUID just do

    Uuid::generate()

This will generate a version 1 with a random ganerated MAC address.

To echo out the generated Uuid cast it to a string

(string) Uuid::generate()

Uuid::generate()->string

Advanced Usage

UUID creation

UUID V1

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');

UUID V3

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

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

UUID V4

Generate a version 4, truly random, UUID

Uuid::generate(4);

UUID V5

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

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

Additional Features

Import UUID

To import a UUID

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

Extract Time

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

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

Extract Version

Extract the version of an UUID

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

Eloquent UUID Generation

If you want an UUID magically be generated in your Laravel models, just add this boot function to your Model.

/**
 *  Setup model event hooks
 */
public static function boot()
{
    parent::boot();
    self::creating(function ($model) {
        $model->uuid = (string) Uuid::generate(4);
    });
}

This will generate a version 4 UUID when creating a new record.

Model Binding to UUID instead of Primary Key

If you want to use the UUID in URLs instead of the primary key, you can add this to your model (where 'uuid' is the column name to store the UUID)

/**
 * Get the route key for the model.
 *
 * @return string
 */
public function getRouteKeyName()
{
    return 'uuid';
}

When you inject the model on your resource controller methods you get the correct record

public function edit(Model $model)
{
   return view('someview.edit')->with([
        'model' => $model,
    ]);
}

Validation

Just use like any other Laravel validator.

'uuid-field' => 'uuid'

Or create a validator from scratch. In the example an Uuid object in validated. You can also validate strings $uuid->string, the URN $uuid->urn or the binary value $uuid->bytes

$uuid = Uuid::generate();
$validator = Validator::make(['uuid' => $uuid], ['uuid' => 'uuid']);
dd($validator->passes());
