    Replace your php code with this:

    <?php
if (!empty($_POST)) {
    $from = $_POST['from'];
    $to = $_POST['to'];
    $number = range($from,$to);
    print_r($number);
}
?>

    To access a form post in PHP you use the $_POST superglobal. More info found here: http://www.php.net/manual/en/reserved.variables.post.php.

    I've put a check to see if it's empty or not at the start, so when the page first loads it won't attempt to run the PHP code. Presumably you'll then replace the print_r with whatever you need to insert the data into your database.
