Comment my small PHP3 solution (Score 1) 189
I solved this for my purposes with a very little PHP3 function (10 lines, only one swicth() call). Now I have only _one_ source file for each multilingual page (no database needed).
Examples available.
Languages are selected via ?language=xx tags appended to the URL.
Of course it's not a solution for a big site and by far not perfect.
