Working with Value Objects in PHP

These are the files used in my talk "Working with Value Objects in PHP".

Requirements

• PHP 7.4+

Using Docker

You can use Docker to run the examples in this project, for example:

docker run --rm --volume $(pwd):/files --workdir /files  php:7.4-cli-alpine php samples/auto-validation.php
