PHP broke

["Mark Corsi" <mcorsi spearreport com>]

Hey Guys -

I am using Red Hat Enterprise Linux 5.x.

I have been doing a lot of development on a testing box for transfer over to
our live server. I am not sure what step 'broke' the box, but I can no
longer get php to function through the webserver. 

A simple php page with:

<?php phpinfo(); ?>

Produces the following error in the log file:

[Wed Feb 13 11:18:48 2008] [error] an unknown filter was not added: PHP


Does anyone know what might be broken here? PHP is installed and runs from
the command line.

Thanks -

Mark
