Are there any built-in PHP functions that can be used to redirect users based on Form Token validation?

To redirect users based on Form Token validation in PHP, you can use the header() function to send a raw HTTP header to perform the redirection. After validating the Form Token, if it is correct, you can use header('Location: new_page.php'); to redirect the user to a new page. If the Form Token is not valid, you can redirect the user to an error page or back to the original form.

<?php
session_start();

// Validate Form Token
if ($_POST['token'] !== $_SESSION['token']) {
    header('Location: error_page.php');
    exit;
}

// If Form Token is valid, redirect to new page
header('Location: new_page.php');
exit;
?>
