In this chapter we've looked at how we can internationalize programs with the least amount of effort. We've seen that you can use several different techniques – pure PHP with or without objects, and the Gettext library.
We've also seen how easy it is to get information about the user's preferred language from their browser. By using this information, you can be sure to send a page in the correct character encoding.
Finally, we stepped through examples that were simple and a clear basis to extend and experiment from. In addition we traversed some more real world code challenges that demonstrated some work arounds to the regular approach and some architectural suggestions for actually getting something done in non-linear language constructs.
