Using AJAX for an auto-refresh page containing values ​​from a database?

Question

Can someone explain how to create a .php page that automatically updates values ​​from the database? Would using AJAX be better for something like that? I need this PHP code, but I want the page to be updated whenever "values01" is added or changed, without having to refresh the page. Any help would be appreciated! :)
$query = "SELECT values01 FROM users WHERE username='$username'";
$result = mysql_query($query);
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
echo nl2br("{$row['values01']}");
}
