IIS7 doesn't call php-cgi?

[Valer...@iengeo.de]

Hi, everybody,

I'm trying to set up PHP on a Windows 2008 server with IIS7, but for some
reason the web server sends out the uninterpreted php source code. Here's
what I did so far:

* downloaded PHP and installed it in C:\PHP\
* added the "CGI" role service to the IIS role
* prepared a php.ini in C:\PHP\
* set up a handler mapping *.php in IIS as a fast-cgi module pointing to
C:\PHP\php-cgi.exe
* used the icacls to grant access to the C:\PHP\ and C:\inetpub\wwwroot\
to user IUSR [(OI)(CI)(M)]
* added C:\PHP\ to the server's PATH variable
* added permission for C:\PHP\php5.dll into ISS's "ISAPI and CGI Restrictions"
* tested the PHP by manually calling "C:\PHP\php-cgi < info.php > test.html"
and verifying that test.html displays the desired result. (The file
info.php contains the usual "<?php phpinfo(); ?>" command.)

I can http-access files from the web server. Calling up a PHP file only displays the PHP source code, though, so for some reason IIS doesn't invoke
php-cgi (or ignores its output).

Did I forget something? Any tips how I could get the system to process my PHP files? Thank you for any suggestions!
