It's kept around for backwards compatibility in projects that were already using it. However, we do not maintain this project and do not advise you to use it in production. --- ValueObjects ============ [](#valueobjects) [![Build Status](https://camo.githubusercontent.com/c41e5f78ebb4987bf1e70282e9310197d1523b75054d3767e212921076ecbbfc/68747470733a2f2f7472617669732d63692e6f72672f6e69636f6c6f7069676e6174656c6c692f76616c75656f626a656374732e706e673f6272616e63683d6d6173746572)](https://travis-ci.org/nicolopignatelli/valueobjects)[![Scrutinizer Quality Score](https://camo.githubusercontent.com/9220ad369615d35b49774654281d96bcf39ae99a227d21128dbfba66ee7fb955/68747470733a2f2f7363727574696e697a65722d63692e636f6d2f672f6e69636f6c6f7069676e6174656c6c692f76616c75656f626a656374732f6261646765732f7175616c6974792d73636f72652e706e673f733d39373935363763326437393166666265616231323737376336306338656462383637373664646363)](https://scrutinizer-ci.com/g/nicolopignatelli/valueobjects/)[![Code Coverage](https://camo.githubusercontent.com/a33da6def007db4505abec4bf1fd63b6ce60a69531cc3c895dd84d7b98a08e34/68747470733a2f2f7363727574696e697a65722d63692e636f6d2f672f6e69636f6c6f7069676e6174656c6c692f76616c75656f626a656374732f6261646765732f636f7665726167652e706e673f733d35396464346131343234313261396463643938393837303631306631633966383963313963663438)](https://scrutinizer-ci.com/g/nicolopignatelli/valueobjects/)[![SensioLabsInsight](https://camo.githubusercontent.com/7fea095f150ae2ac264e2cd9690dd95d619ae8ca758d642b432477f466ccde7a/68747470733a2f2f696e73696768742e73656e73696f6c6162732e636f6d2f70726f6a656374732f32343661326461362d666664622d343733302d393231362d3634376662376161633338332f6d696e692e706e67)](https://insight.sensiolabs.com/projects/246a2da6-ffdb-4730-9216-647fb7aac383) A PHP library/collection of classes aimed to help developers using and undestanding immutable objects. Should I use this library? -------------------------- [](#should-i-use-this-library) Not in production enviroments. Although fully tested, ValueObjects has been developed mainly for educational purposes. Therefore, it can be used in personal projects and to force yourself on thinking in terms of immutable objects and their interaction. When approaching a project using Domain Driven Design, I would suggest to write your own Value Objects in a way they will reflect 100% your domain, without using any library or class designed to solve a general problem more than your specific one. In short, learn from it then throw it away.
