PHP Trait for creating freezable value objects.

For motivation and considerations, see Missing in PHP7: Value objects


To use the FreezableValueObject library in your project, simply add a dependency on wmde/freezable-value-object to your project's composer.json file. Here is a minimal example of a composer.json file that just defines a dependency on FreezableValueObject 1.x:

    "require": {
        "wmde/freezable-value-object": "~1.0"


For development you need to have Docker and Docker-compose installed. Local PHP and Composer are not needed.

sudo apt-get install docker docker-compose

Running Composer

To pull in the project dependencies via Composer, run:

make composer install

You can run other Composer commands via make run, but at present this does not support argument flags. If you need to execute such a command, you can do so in this format:

docker run --rm --interactive --tty --volume $PWD:/app -w /app\
 --volume ~/.composer:/composer --user $(id -u):$(id -g) composer composer install -vvv

Running the CI checks

To run all CI checks, which includes PHPUnit tests, PHPCS style checks and coverage tag validation, run:


Running the tests

To run just the PHPUnit tests run

make test

To run only a subset of PHPUnit tests or otherwise pass flags to PHPUnit, run

docker-compose run --rm app ./vendor/bin/phpunit --filter SomeClassNameOrFilter
