How can the issue of redirected pages not displaying current data be troubleshooted in PHP scripts?
Issue: Redirected pages may not display current data because the browser might be caching the previous version of the page. To solve this issue, you can add cache control headers to the PHP script to ensure that the browser always requests the latest version of the page.
// Add cache control headers to prevent browser caching
header("Cache-Control: no-cache, no-store, must-revalidate"); // HTTP 1.1.
header("Pragma: no-cache"); // HTTP 1.0.
header("Expires: 0"); // Proxies.
