How to make sure that a person does not see the results from the URL of the PHP script?

Question

How to make sure that a person does not see the results from the PHP script url?

Recently, while viewing the source of the site that made the AJAX call, I tried to execute the link in the browser

www.site.com/script.php?query=value

Instead of getting the result that I expected to see, I saw a message stating that only scripts should view this page.

How do you limit the script to the fact that the script has access to it?

UPDATE:

here is the DEMO page page

Answer 1

with php you can only check and show results if the page is called via ajax

function isAjax() {
    return (isset($_SERVER['HTTP_X_REQUESTED_WITH']) && ($_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest'));
}

if(isAjax()) {
    // display content
} else {
    // not ajax, dont show
    echo 'Invalid Request';
}
