Here's the skinny:

I have just upgraded my Fedora Core3 box to Fedora Core 4 (I wanted php5, and being a kinda newbie and after having a lot of problems trying to install it, I just decided to upgrade fedora since it had the new version pre-installed). The upgrade went smoothly, but php5 does not seem to be working. I know that Apache is up and running AND that it says the php5 module is loaded. I found this out by trying to add the line

LoadModule php5_module /usr/lib/httpd/modules/libphp5.so

to the httpd.conf and upon doing so, got a warning saying the php5 module was already loaded. Yet, when I load a page with php content (LogIn.php for example), it dumps the code to the browser instead of executing it.

I can run php from the command line and get correct ouput, for example ?>php ./LogIn.php

What am I doing wrong, I am guessing it is a problem with my apache configuration

Info:

Check that the Directory Index section in your httpd.conf has index.php as one of the listed indexes. If not add it to the list.

I actually just found the source of the problem. When I upgraded to Core 4, it generated a new configuration file for apache (httpd.conf.rpm...something). I am not sure if it was Fedora or if it was Apache that generated this file, but It was this new config file that apache needed to work correctly. I guess it doesn't replace httpd.conf so as not to hose your old config settings. Anywho, I renamed httpd.conf.rpm... to httpd.conf and things started working again.

Thanks for your input, checking the webroot was a good idea that hadn't thought of ^_^

Thats the way rpm is deigned, it does not overwrite most config files by default. I should have thought of that since you said you did an upgrade.
