Is there any code before the print_r() call, i.e. code that might be
setting it to an empty array?

If not, then are you sure your form is definitely sending post
variables? It sounds a stupid question, but a small typo could be
sending the data as GET by accident. Firefox has a useful extension
called Firebug which might be able to show you the data being sent to
the browser. If you really need to bring out the big guns, then
Wireshark will show all the network traffic, including that sent from
your form to the server.
