The code behind Five Filters' content extraction is actually open source, and is based on Readability's original Javascript (before they became a service).

You should be able to use it like this:

$page = file_get_contents($item_url);
$readability = new Readability($page);
if ($result = $readability->init()) {
    $content = $readability->getContent()->innerHTML;
}
