I've never seen this myself, and I don't know PHP, but perhaps the
period has special significance in PHP variables?
Assuming that this might be expected behavior, you could try
URI-encoding the periods with %2E. The browser will still display and
handle it as a period, but you'll need to decode it when it gets sent
back. I would be highly surprised if PHP didn't have a function or
library or something to make this easy.
