Error 404 configuring php

I am trying to get a touch of PHP, MySQL and Apache on my Windows XP Machine before i use it on Linux but i got stuck with PHP. I using php 4.3.3 to work with Apache 2.0.47, and MySQL 4.0.15, Actually im using a CD and a Book: "SAMS Teach yourself"... Apache and MySQL are both working fine but when i unzip php and configure it to work with Apache and i go to test it, i don't get the results of phpinfo(). I get an Error HTTP 404 - File Not Found page. I've tried many things to get it working but i have no idea what is the problem. I've re-installed all three programs but i still get the same thing. I've followed the exact same instruction on the book cause i thought that i was doing something wrong but nothing works.. Any help will be greatly appreciated Thanks In Advance!!!!!! -- Oscar Rene Giron #28 St. Luke st. Belmopan, Cayo District Belize C.A.
