[Xitami] PHP-scripts are not running

[Irmgard Schwenteck]

Hello

I have installed xitami to learn php. When I try to open a php-file, the
browser wants to save this file like an unknown filetyp. The extensions
.php, .php3 and .php4 are registrated in the filter-section of xitami.cfg.
PHP.exe and the DLLs are saved in the Xitami-directory. In the php.ini I
have changed the entry for extension_dir to ./e:\xitami	(E is my
NT4-drive).
What is wrong? 

Thank you for help
