In what situations can pressing Ctrl + F5 help resolve PHP form submission issues?

Pressing Ctrl + F5 can help resolve PHP form submission issues when the browser cache is not properly cleared, causing the browser to display cached data instead of fetching the updated form submission data from the server. By forcing a hard refresh with Ctrl + F5, the browser will reload the page and fetch the most recent data from the server, potentially resolving any form submission issues related to cached data. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form submission data here
}
?>
