OS : Windows XP Media Center with SP2

Web Server: IIS 5.1

My purpose is to install and use wikipedia as a base for my colloborative online consultancy website.

I have downloaded wikipedia latest and PHP 5.x latest recently.

I donot know whether my PHP installation is successful or not. I could be able to open http://localhost from IE 5.1, but not in Mozilla FireFox after installing it. I need to confirm PHP installation before proceeding to wikipedia installation.

I have already completed wikipedia installation as per procedure. But nothing seems to happenning.

I also require some resources to start a feature like Yahoo!Answers (but not RSS Feeds please) and also a online library for reference, a forum, on linux server. I thought wikipedia is a better platform, but open to other solutions also.

I'm not sure I can answer all your questions, but...here goes nothing...

i'm not sure about the wikipedia stuff, but to test if your php installation worked, create a .php file with this in it:

<?php

phpinfo()

?>

save it to your /var/www/html directory and open it, or just save it to where it's going to be able to run through your web server. Access the file, and if it shows a bunch of info about your server, that means your installation is good.

If you want some sort of forum, it's good that you've already got php going. I'd recommend phpbb. It's free, easy to install, and there's a lot of info out there about it. Hope this info helps :)
