Here are two quick and dirty functions that use SimpleXML to detect if a feed xml is RSS or ATOM:

function is_rss($feedxml) {
    @$feed = new SimpleXMLElement($feedxml);

    if ($feed->channel->item) {
        return true;
    } else {
        return false;
    }
}

function is_atom($feedxml) {
    @$feed = new SimpleXMLElement($feedxml);

    if ($feed->entry) {
        return true;
    } else {
        return false;
    }
}

The functions take in the full text feed (retrieved via cURL, for example) and return a true or a false based on the result.
