Windows XP
Apache 2.2.4
PHP 5.2.3

My Level: Biginner - non technical (UK Based)
I'm trting to setup on a standalone local PC so that I can learn about 
PHP/MySQL/Apache

I have Apache up and running and I am trying to get PHP 5.2.3 working with 
it. When I try loading the test.php file all I get is the code <? phpinfo(); 
?>.

I'm not really sure where to start to narrow down the problem. Can onyone 
help please.
