Apache Doesn't' Process php Files

I am having trouble getting Apache to process php files through the PHP interpreter. When I view a *.php file in a browser, I see my PHP source. I am running Apache 1.3.20 on a RAQ4. The web server was installed before I became involved in this project. I have successfully installed PHP 4.1.2 and can run it interactively from the command line. The php.ini file is in /etc/httpd. I have the following lines in my httpd.conf file: # Extra Modules #LoadModule php_module modules/mod_php.so #LoadModule php3_module modules/libphp3.so LoadModule php4_module modules/libphp4.so # Extra Modules #AddModule mod_php.c #AddModule mod_php3.c AddModule mod_php4.c AddModule mod_perl.c #AddModule mod_casp2.c AddType application/x-httpd-php .php4 AddType application/x-httpd-php .php The last two lines are actually in the VirtualHost section for the site that I am trying to use. I have restarted the web server several times. What else do I need to check? What could be preventing Apache and PHP from playing nice together? -- Bruce Vander Werf brucev@cyberlink.com
