ICU is widely used and has both C/C++ and Java implementations. This means that the concepts around working with in PHP translate well if you are doing globalization work in other (programming) languages.
The intl extension is bundled with PHP versions 5.3.0 and later. To use it with PHP 5.2.0 or later, install it from PECL.
