Value Object

The experiment I began a few years ago resulted in a modest library that I continue to utilize to this day.

It is available on Packagist / GitHub and you can read more about it on Medium.

The library is also a key focus of an article at PHP Architect, which I had the pleasure of publishing.

The library contains the unit tests written using the PHPUnit framework, but there have also been phpspec tests created (BDD), which can be found in the value-object-spec repository.
