$PATH_INFO is your friend when it comes to creating clean URLS. Take for example this URL:

http://www.company.com/products/routers

If the Apache configuration contains this block:

<Location \"/products\">
ForceType application/x-httpd-php
</Location>

Then all you have to do is create a PHP script in your DOCUMENT_ROOT named \’products\’ and you can use the $PATH_INFO variable which will contain the string, \’/routers\’, to make a DB query.
