Redmine

Hello! Does anybody know, does it work?
Now, I'm trying to send issues via php.
I'd found all information such:
http://www.redmine.org/projects/redmine/wiki/Rest_api
http://www.redmine.org/projects/redmine/wiki/Rest_api_with_php

But it doesn't work...
First, I've found ActiveResource.php (don't remember where)
and write index.php:
@@
if (! extension_loaded ('curl')) {
echo 'cURL extension not loaded.';
exit();
}

require_once ('ActiveResource.php');

class Issue extends ActiveResource 
{
//        echo base64_encode("belov:123456");
        var $site = 'http://belov:123456@10.10.1.40:3000/issues';
        var $request_format = 'xml'; // REQUIRED!
    }

$issue = new Issue (array ('subject' => 'XML REST API', 'project_id' => '1'));
$issue->save ();
echo $issue->id;
@@

But I got the mistake. Redmine said, that ther are no Content-length but redmine need it...

I rewrote ActiveResource.php like this:
curl_setopt ($ch, CURLOPT_HTTPHEADER, array ("Content-Type: application/x-www-form-urlencoded", "Content-length: ".strlen($params)));
instead this:
curl_setopt ($ch, CURLOPT_HTTPHEADER, array ("Content-Type: application/x-www-form-urlencoded"));

Well. Redmine accepted the XML, but I've got internal serve Error 500 with this log:
Processing IssuesController#create to xml (for 10.10.0.4 at 2011-02-03 10:23:42) [POST]
Parameters: {"format"=>"xml", "project_id"=>"1", "action"=>"create", "subject"=>"XML REST API", "controller"=>"issues"}
Form authenticity token is missing or is invalid. API calls must include a proper Content-type header (text/xml or text/json).

I was playing with headers (like "text/xml", "application/xml" and other) but it didn't help.
It seams, that it can't athorise with my login|password.
Via C# I can connect and send the new issue. It's no problem, but I need to realise it via PHP.

Anybody, help!
