Apache server propblems

a while back i installed the apache server to run a small web site for my classroom on and i had somebody help me set it up with PHP 5 and i no longer need the PHP 5 and i just need the server back to the original configuration. I have tried to reinstall the Apache and to no vail to have it back up and running. I am needing so help on how to put the Apache back to where it was and I do not know what I had changed for the set up of PHP 5 to put it back to normal.

You have this in your computer or in a server ?

If it's in a computer than haven't you tried uninstall and remove both Apache and PHP and then installing both again ? Now PHP don't support versions below 5.x so why not keep the latest version ?

Agreed. I would just leave it there. PHP5 is pretty standard these days and saves you having to re-configure your server when you decide you want it back again.
