Hey, I followed this tutorial here: http://www.thesitewizard.com/php/install-php-5-apache-windows.shtml and I've done it twice now and checked everything, but PHP simply wont work and only asks to save the PHP file when using Apache. So, what else is there to do? Am I missing something?
This would indicate that PHP is not being invoked, and the server-side script file content is simply being sent verbatim to the browser. Please see the tutorials in our PHP server-side scripting forum for instructions on installing PHP as a module or as a CGI (whichever your server supports).
I'd suspect you've installed it "the wrong way" for the method that your server actually supports.
