I'm new to PHP, found and installed XAMPP - and was able to run the C:/xampp/htdocs/xampp/splash.php file by entering http://localhost/xampp/splash.php in Firefox.
But when I try to save & run a simple script named c:/xampp/htdocs/xampp/MYphpinfo.php using http://localhost/xampp/MYphpinfo.php
<?
phpinfo();
?>
it doesn't run - or all I get is a blank page.
So, what is the rule for locating files in the XAMPP folder, and what is considered the "root" folder?
