Answer 1

Typically people set a variable to check if a file was included or not, Why not do something like this? In your index file

<?php
$fromIndex = true;
include 'viewannouncement.php';
?>

Then in your file viewannouncement.php, try this at the top.

if(!isset($fromIndex)) {
  header('Location: /index.php');
  die;
}
