What is the issue with displaying the updated value from the database in PHP after submitting a form?

The issue with displaying the updated value from the database in PHP after submitting a form is that the page needs to be refreshed or the updated value needs to be fetched from the database again to display the most recent data. To solve this, you can either redirect the user to a new page after the form submission that fetches and displays the updated value, or use AJAX to dynamically update the value on the current page without a full page reload.

// Assuming the form has been submitted and the database has been updated
// Redirect the user to a new page to display the updated value
header("Location: updated_page.php");
exit;
