In order to get the PATH_INFO to work in order to pass parameters using a hidden program/trailing slash/"pretty url" in more recent versions of PHP you MUST add "AcceptPathInfo On" to your httpd.conf.
AddType application/x-httpd-php .php .html
AcceptPathInfo On
Try it out with your phpinfo page and you'll be able to search for PATH_INFO.

If you want to drop the .php use one or both of these:
DefaultType application/x-httpd-php
ForceType application/x-httpd-php
