To Besta and 'j dot b..dot sk':
'Add Module mod_php4.c' or 'AddModule mod_php5.c' may or may not be necessary depending on your environment and version of Apache.
In my situation, this add module DID NOT work or it wasn't necessary. The LoadModule was enough to do the trick. I tried it with PHP4 on Apache 1.3.34 and Apache 2.0.
All in all, your notes have been helpful. Thanks.
