A Symfony polyfill library that provides the idn_to_ascii and idn_to_utf8 PHP functions for environments lacking the Intl extension. It enables internationalized domain name handling in pure PHP.
Use cases
- convert internationalized domain names to ascii in php
- use idn_to_utf8 without the intl extension
- handle unicode domain names on hosts without pecl intl
- make my php package depend on idn functions portably
- polyfill intl idn functions in legacy php projects
When to choose
- your PHP runtime lacks the ext-intl extension but you need IDN conversion
- you build portable PHP libraries that must work with or without Intl
- you want a lightweight, MIT-licensed shim maintained by Symfony
When to avoid
- the Intl extension is already installed on your server
- you need full ICU internationalization beyond IDN functions
- your project is not PHP-based
