How to make sure a human doesn't view the results from a PHP script URL?
Recently when viewing the source of a site that was making an AJAX call, I tried to follow the link in the browser
www.site.com/script.php?query=value
Instead of getting the result I expected to see, I saw a message stating only scripts should view that page.
How do you restrict a script to only allowing a script to access it?
UPDATE:
here is the page DEMO page
