You should check the 'Accept-Language' header [1] that the client usually sends: $languages = $_SERVER['HTTP_ACCEPT_LANGUAGE']; you'll have a string like: en;q=1.0, de;q=0.9, da;q=0.1 meaning that the user prefers english but if you don't have an english translation, give me german, and last but not least, I can read danish a bit. If the client doesn't have the header then direct them to a page that has them select their language choice. Then handle their choice with session data [2]. I would have the session data override the Accept-language header so that the user can manually override his browser settings. You can see how google [3] does things by modifying your language settings in your browser and your personal google settings. IMO they have a very nice language detection system.
