PHP from CD-ROM

I'm running a web site where I also want to be able to deliver a version on CD-ROM. The live web site contains links to PHP files, which obviously won't work if the end user is accessing the CD-ROM from their home computer. Right now, if the user clicks a link to a .php served from the CD, the browser fills the window with PHP source -- obviously not the best solution. Yes, I could produce a version which does not use PHP -- the links instead go to pages that say 'you have to be online to use this'. However, I don't want to get into multiple versions if I don't have to. I'm going to check out Javascript to see if there's a way to differentiate the cases. Has anyone come up with a better solution for this? ...................................................................... Les Neste Cellphone 678-778-0382 Web http://www.lesneste.com
