README

Create a new Ulid() anywhere in your application, and you have a stringable object that can be used as the primary key in a database. Ulid strings look something like 01G2J6MYN0PGC5Q21W9C or can be prefixed with a type like CUSTOMER_01G2J6MYN0PGC5Q21W9C. They are cryptographically pseudo-random, and sort so that newer Ulids compare "greater than" older Ulids.

This solves the problems exposed with working with auto-incrementing integer primary keys, which are predictable and difficult to work with in distributed databases.

Example usage:

use GT\Ulid\Ulid;

$exampleDataSource->create(new Person(
	new Ulid("pet"),
	name: "Cody",
	age: 5,
));
