PHP 5.3 and the Internationalization extension
In this article, Stas Malyshev describes the internationalization extension and mentions it’s been included in the PHP 5.3 core. It is an extensive article with plenty of examples to explain every component of Internationalization: Locale, Collator, Number formatter, Date formatter, Message formatter, Normalizer, Grapheme and Internation Domain Names.
Pretty useful. Storing it for later (when Dokeos will require 5.3 by default, or the installation of the extension in 5.2)
