Knoppix comes with php built into apache.
To view your webpages from knoppix, you could try edit your /etc/apache/httpd.conf file.
Find lines that says:
# This should be changed to whatever you set DocumentRoot to.
#
<Directory /var/www/>

change it to where your webpages location :
ex: Directory /mnt/hda1/myweb

Don't forget to mount your windows partition and run /etc/init.d/apache start
Then open konquerer and point to your ip address/your.php or index.html (after you set a static ip, using netcardconfig).
