TranslationHelper
This uses the HTTP_ACCEPT_LANGUAGE to determine the current users most accepted language. It takes the the first one of all accepted, then looks up the available translations and delivers. If all fails, or no good translation was found, it returns the default string.
Usage
Download code
$trans->text(array('default'=>'Title',
'de_de'=>'Titel',
'fr_fr'=>'Titre',
'it_it'=>'Titolo')
);
