Does mod_php4 include php4?

[S W]

Dear all,

I'm setting up apache/snort/acid/mysql, etc, and need php4 for acid.

Acid needs (or certainly used to) phplot, which needs mod_php4, but if
I attempt to install mod_php4 (needed for phplot) on top of php4, it
complains that it and php4 install to the same place (and vice-versa).

I have come across a post which suggests that mod_php4 includes php4 -
can anyone confirm this?

Best wishes,
boink
