problems in setting up php on sarge

["Raymond Still" <rstill@canada.com>]

Hello,
This is my first Linux install, so any help would be
very much appreciated.
I'm currently trying to setup Apache and php on a new
sarge install. Apache works. The only thing I had to
figure out was the web root and that wasn't too bad.
However, it just won't parse php.
I have spent an evening on google and man pages, but
I'm not getting anywhere. 
I selected webserver on the sarge installer. (RC3 if it
matters) 
For a test case, I added
<?php
echo"hello";
?>
to the bottom of the apache default page (just above
</body>)
The php code shows when I select view source code in
mozilla, but it doesn't parse.
any hints, help, or suggestions greatly appreciated.
Thanks
Ray
