I18n is short for internacionalization. Means several languages in one application.

Widgets have a special attribute LANG so you can define in which language are the made.

Lets see a simple example:

<titlebox lang="en" title="What is BIF?"> Build it Fast (BIF) is a PHP Framework. It contains several classes that help you develop complex Web applications in a short amount of time. It brings the concept of the 'widget' to Web development. It features Cascade Skins and transparent session management. </titlebox> <titlebox lang="es" title="¿Qué es BIF?"> Build it Fast (BIF) es un marco de trabajo (framework) escrito en PHP. Contien varias clases que te ayudan a desarrollar aplicaciones web complejas en un período de tiempo corto. Utiliza el concepto de 'widget' en el desarrollo web. Hace uso de Pieles y manejo de </titlebox>

As you can see lang="en" and lang="es" defines the language titlebox contents are in.

In order to configure your application with this behaviour, you should include in your bifConfig.inc.php:

$bifcfg['i18n']['supported'] = array('English' => 'en', 'Español' => 'es', ); $bifcfg['i18n']['default'] = 'en';

If you access that page with ?bif_lang=en or ?bif_lang=es you'll see diferent content. Showing one or other paragraph. You can include a language selector use 'BifLangSelector' widget.

If you need to split languages in diferent files -that's for example English and Spanish in two different files- you could use BifInclude in this way:

<BifInclude src="Content/index_en.bif" lang="en" /> <BifInclude src="Content/index_es.bif" lang="es" />

Note the directory is relative to $app_dir! and the language specific content will be in separated files.
