In /etc/apache/httpd.conf, uncomment the line near the end of the file so that it reads:
Code:
Include /etc/apache/mod_php.conf
As mentioned in httpd.conf, you'll need to make sure you have the appropriate packages installed. You'll also want to take a look at /etc/apache/mod_php.conf and /etc/apache/php.ini, but for normal usage you won't have to change anything in these files.
