Hi Audrey

There are many ways of doing this in any serverside language. You can use the methods you mention above or use IP verification to determine the users origin. The favoured method for quick and simple is to use variables for your outputs stored in a language pack. You could offer users a flag or child menu to switch language or create a cookie to auto switch the language file if you have a good volume of returning visitors. It really depends upon your sites needs as to how you go about creating the application.
