I know no way of disabling the back button, but the code that you are using just makes it so the user doesn't cache the page, this is helpful for pages with dynamic content.

See this page:
http://www.php.net/manual/en/function.header.php
The code was good for me:
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
// always modified
header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache"); // HTTP/1.0
