HTTP Put via php client - php

Question

I'm writing a small 'app' for a accounting site called Xena.biz
The system has an API that uses oAuth2 to connect to. All that I have sorted out - I can perfectly retrieve the information I need. Now I need to submit a PUT string back to Xena - here is where I can't figure it out.
The system is build on a file called XenaClient.php which contains all the authorization calls and all the requests.
Here is an example on how I retrieve information :
<?
require('XenaClient.php');
const CLIENT_ID = 'SECRET';
const CLIENT_SECRET = 'VERY SECRET';
$xenaclient = new XenaOAuth2Client(CLIENT_ID, CLIENT_SECRET);
$xenaclient->setAccessToken($_COOKIE["MaskedCookieName"]);
$ordertask = $xenaclient->fetch('https://my.xena.biz/Api/Fiscal/'.$_GET["fiscal"].'/OrderTask/'.$_GET["orderId"]);
var_dump($ordertask);
?>
But now I want to SEND information via PUT. According to the XenaClient.php script, I should use the command $xenaclient->fetch($url,$parameters);
So this is my shot
require('XenaClient.php');
const CLIENT_ID = 'SECRET';
const CLIENT_SECRET = 'VERY SECRET';
$xenaclient = new XenaOAuth2Client(CLIENT_ID, CLIENT_SECRET);
$xenaclient->setAccessToken($_COOKIE["MaskedCookieName"]);
$xenaclient->fetch('https://my.xena.biz/Api/Fiscal/96946/Order/243936250/Confirmation',array('ConfirmationDate'=>NULL,'ConfirmationReportLayoutId'=>261205291));
?>
This doesn't turn anything back, or doesn't create the wanted effect inside the accounting system. No help to get from Xena themselves, so this is why I ask you guys, hope you can help me.
Heres a few pointers:

XenoOAuth2Client::fetch tells you, that the third parameter to the fetch function - although optional - determines the method of the request. Default ist GET (XenaOAuth2Client::HTTP_METHOD_GET), so if you want PUT, you should explicitly provide the appropriate PUT parameter (other methods see the XenoOAuth2Client class constants:
$xenaclient->fetch(
'https://my.xena.biz/Api/Fiscal/96946/Order/243936250/Confirmation',
array('ConfirmationReportLayoutId'=>261205291),
XenaOAuth2Client::HTTP_METHOD_PUT
);
most APIs consume json today, perhaps it's supposed to be json...
$xenaclient->fetch(
'https://my.xena.biz/Api/Fiscal/96946/Order/243936250/Confirmation',
json_encode(array('ConfirmationReportLayoutId'=>261205291)),
XenaOAuth2Client::HTTP_METHOD_PUT
);
