What could be causing the issue of offline data being loaded instead of the preview text in a PHP form?

The issue of offline data being loaded instead of the preview text in a PHP form could be caused by the browser caching the previous data. To solve this issue, you can add a random parameter to the URL of the preview text request to ensure that the browser fetches the latest data every time.

php 
<?php
$preview_text_url = 'https://example.com/get_preview_text.php';
$preview_text_url .= '?rand=' . uniqid(); // Add a random parameter to the URL

$preview_text = file_get_contents($preview_text_url);
echo $preview_text;
?>
