uuid
====

[](#uuid)

Provides a native PHP implementation of UUID creation.

This class supports version 4 (random) and version 5 (SHA-1) UUID generation algorithms. It generates the DCE 1.1 variant UUID, the most common outside of Microsoft environments.

The UUIDs generated are RFC 4122 compliant.

Introduction
------------

[](#introduction)

### Installation

[](#installation)

This class only requires PHP 4 or later, but we recommend using the latest available version of PHP as a matter of principle. It has no dependencies.

It is installable and autoloadable via Composer as \[cxj/uuid\] ().

Alternatively, \[download a release\] () or clone this repository, then require or include its *autoload.php* file.

### Quality

[](#quality)

This class attempts to comply with [PSR-1](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-1-basic-coding-standard.md), [PSR-2](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md), and [PSR-4](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-4-autoloader.md). If you notice compliance oversights, please send a patch via pull request.

### Design Goals

[](#design-goals)

This class was designed to cover only the most common use cases, and to be small and lightweight. Hence, there are some features it does not provide.

In particular:

- It does not provide a version 1 (MAC address) implementation, because there is no reliable and lightweight method to obtain the MAC address from PHP. There are also criticisms of version 1 which make it less desirable.
- Version 2 (DCE Security) is also not presently implemented. The need for this version appears small.
- It does not provide a version 3 (MD5) implementation. MD5 has been shown to have weaknesses, and version 5 (SHA-1) is recommended for usage instead.
- It is a UUID generator, so very little UUID parsing and validation is part of the code at present.

Usage
-----

[](#usage)

The UUID generation methods are static, so simply call them as shown below.

Pull requests are welcome!

Requests which follow the PSR-1 and PSR-2 coding and style standards, and which have PHPUnit test coverage will get most attention.
