How can PHP be used to redirect users back to a previous page while clearing session data for form fields?

To redirect users back to a previous page while clearing session data for form fields in PHP, you can use the header() function to redirect the user back to the previous page and then unset the session variables storing the form field data. 

<?php
session_start();

// Clear session data for form fields
unset($_SESSION['form_field_1']);
unset($_SESSION['form_field_2']);
// Add more unset statements for additional form fields if needed

// Redirect back to previous page
header('Location: ' . $_SERVER['HTTP_REFERER']);
exit;
?>
