I have loaded XAMP and read a lot of the how tos but I still can't process my php scripts from my PC?
What is happening then? Have you got the Apache service running? Are you accessing the files via http://127.0.0.1 as opposed to the filesystem?
Are you sure Apache and Wamp are running? Left click the wamp server on your toolbar and start apache and wamp if they are not running. If I recall correctly, localhost/index.php should show your server configuration, tools (phpinfo(), PHPmyadmin and SQLitemanager), as well as any projects you start. To run any php file, make sure it is in the folder you set your working folder to (install directory\wamp\www\, I forget what the default folder is)
You probably didn't put your PHP files into Xampp folder. I don't have Xampp installed but if I'm not mistaken you have to put your files into C:/.../xampp/htdocs/xampp/. Hope this helps.
