Beats me, but Apache seemed fairly easy to me, although there have been some problems around (some months ago a person with the exact same software and configuration simply couldn't make it work). PHP and Apache make a nice couple, and it can't be too hard to get them to work. Why don't you tell us the problem?
BTW server software runs better on NT based systems (for ex. XP) than 95 based ones, as they can run in the background as system services.
