php/apache installation

Hi,

i'm new to PHP, and i'm trying to install it on my computer, not as a server 
though. 
I am using Win98.
I have installed Apache, and it seems to have installed properly, as when i 
point the browser at http://localhost/ it comes up with the apache page. 
However, when i try and run a script 
(phpinfo.php, containing "<? phpinfo() ?>" located in "apache 
group/apache/htdocs") it comes up with a 404 error - page not found. I have 
checked the installation, as recommended at 
http://hotwired.lycos.com/webmonkey/00/44/index4a_page10.html?tw=programming 
and can find no errors, i just copied and pasted from there. 

Any ideas, anyone???

Adam.
