off track but php on cf server

i wanted to do some php on my platform

winXP-pro sp3

cf server

msSQL2000 server

msSQL2005 server

so added as per instructions

,net framework

fastCGI

mySQL 5.2

php 5.3

i used the install software from microsoft or that came with the program and all looks nice. cf still runs ok but calling a php doc via localhost does nothing or at most a pop-up window asking if i would like to save.

.php is showing in extensions

any ideas would be appreciated.

tnx
