Please URL Rewrite in php

I would like visitors to access the page by typing www.site.com/12 instead of www.site.com/room/doorstep.php?page_id=12

The IDs are many so i cannot create folders. What is the code needed to do this? I am trying to do this through .htaccess but I have not been successfull. Please help me with this.

Dennis.

The problem with the www.site.com/12 setup, is it makes it a bit tricky to do, as if you want to actually add a physical page called 1000 your setup may not work right (which may also depend on multiviews). Instead I would steer away from that and do something like:

www.site.com/room/12 or www.site.com/room/id/12

The .htaccess redirect for that would be something like:

RewriteRule ^room/id/(.*)$ room/doorstep.php?page_id=$1 [L]

That should give you the example you need to get the show on the road.

EDIT

What might even be better is just match a number:

RewriteRule ^room/id/([0-9]+)$ room/doorstep.php?page_id=$1 [L]

Which would only return true if a number was passed, since that is what your ID's seem to consist of.

Assuming you've got mod_rewrite set up in Apache, you can do the following in your .htaccess

RewriteEngine On
RewriteRule ^([0-9]+)$ room/doorstep.php?page_id=$1 [L]
