<?php // Script 3.3 handle_form.php
ini_set ('display_errors', 1);//Let me learn from my mistakes!
// This page receives the data from feedback.html.
// It will receive: title, name, email, response, comments, and submit in

$title = $_POST['title'];
$name = $_POST['name'];
$response = $_POST['response'];
$comments = $_POST['comments'];
//Print the received data:
print "<p>Thank you, $title $name, for your comments.</p>
<p>You stated that you found this example to be '$response' and added:

You stated that you found this example to be '$response' and added:
