Convert line breaks in php textarea

Question

I have a kind of a guestbook on my page. It's just a common textarea like this:

echo '
<textarea name="msg"></textarea>';

and then I use a form to send me to the backend on submit:

$db = JFactory::getDbo();
$query = $db->getQuery(true);
$jinput = JFactory::getApplication()->input;
$msg = $jinput->getString('msg');
$columns = array('message');
$values = array($db->quote($msg);
$query->insert($db->quoteName('guestbook'))->columns($db->quoteName($columns))->values(implode(',', $values));
$db->setQuery($query);
$db->execute();

But my problem is, that if the user write something like:

Hey.

This is a nice site.

Bye for now!

The guestbook prints out:

Hey. This is a nice site. Bye for now!

How can I get the line breaks from the user-inputs?

EDIT: I echo the results like this:

$results = $db->loadObjectList();
foreach ($results as $row) {
echo $msg;
}

You don't show how you are echoing the result, but have you tried wrapping it in nl2br?
