[gentoo-user] PHP won't execute

[Michael Sullivan]

A several years ago I ran a public network out of my apartment.  I had
email, www, etc. etc.  It all worked fine.  Then one day a couple of
years ago we decided that we could not afford to pay for a public IP
address anymore, so we had it turned off.  I haven't touched apache
since then, but we still run that box as it's faster than all the others
and runs distcc well.  We had a picture page that I wrote back in 2005
and occassionally when we have company over we use it to show them
pictures that we've taken.  I went to the site in my web browser this
evening, and saw only PHP code printed on the background image.  I've
checked the usual suspects:

carter apache2 # cat /etc/conf.d/apache2 
# /etc/conf.d/apache2: config file for /etc/init.d/apache2

# When you install a module it is easy to activate or deactivate the
modules
# and other features of apache using the APACHE2_OPTS line. Every module
should
# install a configuration in /etc/apache2/modules.d. In that file will
be an
# <IfDefine NNN> where NNN is the option to enable that module.
# Here are the options available in the default configuration:
#   USERDIR   Enables /~username mapping to /home/username/public_html
#   INFO      Enables mod_info, a useful module for debugging
#   PROXY     Enables mod_proxy
#   DAV       Enables mod_dav
#   DAV_FS    Enables mod_dav_fs (you should enable this when you enable
DAV
#             unless you know what you are doing)
#   SSL       Enables SSL
#   SSL_DEFAULT_VHOST  Enables default vhost for SSL (you should enable
this
#                      when you enable SSL unless you know what you are
doing)
#   LDAP      Enables mod_ldap
#   AUTH_LDAP Enables authentication through mod_ldap
#   DEFAULT_VHOST Enables the default virtual host
in /var/www/localhost/htdocs
APACHE2_OPTS="-D DEFAULT_VHOST -D PHP5 -D MAILMAN -D USERDIR"

# Extended options for advanced uses of Apache ONLY
# You don't need to edit these unless you are doing crazy Apache stuff
# As not having them set correctly, or feeding in an incorrect
configuration
# via them will result in Apache failing to start
# YOU HAVE BEEN WARNED.

# ServerRoot setting
#SERVERROOT=/usr/lib/apache2

# Configuration file location
# - If this does NOT start with a '/', then it is treated relative to
# $SERVERROOT by Apache
#CONFIGFILE=/etc/apache2/httpd.conf

# Location to log startup errors to
# They are normally dumped to your terminal.
#STARTUPERRORLOG="/var/log/apache2/startuperror.log"

# Environment variables to keep
# All environment variables are cleared from apache
# Use this to preserve some of them
# NOTE!!! It's very important that this contains PATH
# Also, it will fail if the _value_ of any of these variables contains a
space
KEEPENV="PATH"

carter apache2 # cat error_log

(that $filename reference would have resolved if PHP were executed AS
PHP instead of plain text)

See?  There ARE files there.

What am I missing here?  I looked at 
http://www.gentoo.org/proj/en/apache/doc/troubleshooting.xml

and it said that the browser cache might be full, so I closed the
browser, deleted the cache directory files, and reopened the browser.
