Source Code for /private/sample-include.php

/**
 * This PHP file lives outside of the webroot, in the 'private' directory on this webserver.
 * This means that you can't normally access it directly from a web browser, like you can
 * for example with a URL like 'https://php.danq.dev/inc/footer.php'. There is no URL that
 * loads this file directly. Instead, it's only accessed by inclusion within another file:
 * e.g. https://php.danq.dev/appendix-samples/includes-from-outside-webroot.php
 *
 * This PHP code randomly selected 3-4 sentences from a set of Forer-Barnum statements,
 * which are designed to be a selection of the "generic" statements found in e.g. horoscopes.
