Fresh Hoary install, php files not recognized

[Tony]

I performed a clean install of Hoary on my iBook (which was previously
running LAMPhp on Warty).  After installing Apache and PHP4, I created
the phpinfo() to look at the setup.  But when I try to view the file
with Firefox, it does not recognize .php files and gives me an "Open
with", "Save to Disk" window.

Is there an additional setting in Apache that must be set to recognize
.php files?
