php

I'm using PHP to upload an image from a form to the server and want to rename the image lastname_firstname.[original extension]. I currently have:

move_uploaded_file($_FILES["picture"]["tmp_name"], "peopleimages/" . "$_POST[lastname]" . '&#95;' . "$_POST[firstname]")

which, of course, renames the file lastname_firstname without an extension. How do I rename the file but keep the extension?

Thanks!
