Uuid Generator

This class' intent is to encapsulate Uuid's latest and more secure versions removing the need to explicitly hard-code a Uuid version everywhere.

1. Installation

The recommended way to install the Uuid Generator is through Composer. Run the following command to install it:

php composer.phar require nilportugues/uuid

2. Usage

Usage is real simple, you can create your Uuid right away or under certain namespaces.

2.1. Without namespacing

This is the most common case. Usage is straight-forward:

<?php
use NilPortugues\Uuid\Uuid;

echo Uuid::create(); // "13dfa123-d7a6-4082-8b3f-513c28f5d691"

2.2. With namespacing

First of all, the following namespaces exists:

• DNS Namespace
• URL Namespace
• OID (Object Id) Namespace
• X500 Namespace

Code-wise it's use can be defined using a constant.

<?php
use NilPortugues\Uuid\Uuid;

echo Uuid::create(Uuid::NAMESPACE_DNS, 'nilportugues.com');

echo Uuid::create(Uuid::NAMESPACE_URL, 'http://nilportugues.com/robots.txt');

echo Uuid::create(Uuid::NAMESPACE_OID, 'Foo\Bar');

echo Uuid::create(Uuid::NAMESPACE_X500, '/c=us/o=Sun/ou=People/cn=Rosanna Lee');

More on its usage can be found here: http://tools.ietf.org/html/rfc4122#appendix-C

2.3. Uuid versions

Currently Uuid has 5 versions and while all of them are valid, usage of newest versions is always preferred. Lastest preferred versions are:

• Uuid4 preferred over Uuid1.
• Uuid5 preferred over Uuid3 and Uuid1

3. Quality

To run the PHPUnit tests at the command line, go to the tests directory and issue phpunit.

This library attempts to comply with PSR-1, PSR-2, and PSR-4. If you notice compliance oversights, please send a patch via pull request.
