I'm trying to install the latest version of PHP on my home machine for development purposes. I used the installer that comes with one of the Windows versions. I then checked and confirmed everything in the install instructions, as well as the Sitepoint article on using MySQL and PHP. I'm using Personal Web Server(PWS) 4. My problem comes when I go to open a PHP file. The file opens up on the server with nothing where any php code is. I don't see any raw PHP, just emptiness where there should be something filled in by PHP. It's like the server is blind to everything between <?php and ?>.
Any assistance is greatly appreciated. Thanks.
