This sounds pretty terminal, our server was down and we could no longer use moodle. I hadn't changed any settings in php.ini. What had happened was I had manually cleared the php.log file sitting in C:/temp/ without the log file it no longer wanted to serve webpages...(?!). restoring that file, brought the server back up.
