Oihana PHP – Standards
======================

[](#oihana-php--standards)

[![Oihana PHP System](https://raw.githubusercontent.com/BcommeBois/oihana-php-standards/main/assets/images/oihana-php-standards-logo-inline-512x160.png)](https://raw.githubusercontent.com/BcommeBois/oihana-php-standards/main/assets/images/oihana-php-standards-logo-inline-512x160.png)

**Oihana PHP – Standards** is a library of **constants**, **value-objects** and **helpers** built on top of international standards (ISO, IETF, UN/CEFACT, UN M49).

It is designed for **strong typing**, **validation** and **easy lookups** in your PHP 8.4+ applications.
