First off, their docs are almost entirely non-existent. File a bug, or better yet, send them a pull request.

For pings in particular:

$client->require_xep(array(
    '0199'  // XMPP Ping
));

If you want to write your own protocols, look at their XEP-0199 implementation for an example:

public function get_ping_pkt() {
    $attrs = array(
        'type'=>'get',
        'from'=>$this->jaxl->full_jid->to_string(),
        'to'=>$this->jaxl->full_jid->domain
    );

    return $this->jaxl->get_iq_pkt(
        $attrs,
        new JAXLXml('ping', NS_XMPP_PING)
    );
}
