 **A PHP library for generating universally unique identifiers (UUID).**

What is a UUID?
---------------

[](#what-is-a-uuid)

A UUID *(short for Universally Unique IDentifier)* ​​is a 36-character alphanumeric string that can be used to identify information. For example, they are commonly used to identify rows of data in database tables, with each row assigned a specific UUID.

Here is an example of a UUID: `acde070d-8c4c-4f0d-9d8a-162843c10333`

One reason UUIDs are so widely used is that they are likely to be globally unique. In other words, not only row UUIDs are unique within a row. A database table is probably the only row with that UUID on any system.

*(Technically it's not impossible that the same UUID you generate could be used elsewhere, but it's highly unlikely as there are 340,282,366,920,938,463,463,374,607,431,768,211,456 possible different UUIDs.)*
