Laravel package to generate a UUID according to the RFC 4122 standard. Only support for version 1, 3, 4 and 5 UUID are built-in.

Add webpatser/laravel-uuid to composer.json.

"webpatser/laravel-uuid": "1.*"

Run composer update to pull down the latest version of Laravel UUID.

Edit app/config/app.php and add the alias

'aliases' => array(
    'Uuid' => 'Webpatser\Uuid\Uuid',
)

To quickly generate a UUID just do

Uuid::generate()

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

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::nsDNS);

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::nsDNS);

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);

If used on windows it will use the CAPICOM getRandom method
