Event not updated using Google calendar API

I'm trying to update events in a calendar using the google calendar API but I cant get it to work.

Here is my update function.

I'm using pecl's oauth extension.

public function updateEvent($id,$title,$body,$start,$end){

        $calendar = $this->getCalendars();

        try {

            $feed = $this->fetch($calendar['data']['items']['0']['eventFeedLink']."/".$id);

            $feed['data']['title'] = $title;
            $feed['data']['details'] = $body;
            $feed['data']['when']['0']['start'] = $this->jsDateToGoogleDate($start);
            $feed['data']['when']['0']['end'] = $this->jsDateToGoogleDate($end);

            echo json_encode($feed);

            $this->oauth->fetch($feed['data']['selfLink'],json_encode($feed),OAUTH_HTTP_METHOD_PUT,array("Content-Type"=>"application/json","If-Match"=>"*"));

            print_r(json_decode($this->oauth->getLastResponse(),true));

        } catch (OAuthException $e){
            die("ERR : ".$e->getMessage());
        }
    }

I have no error what so ever.

The echo json_encode($feed) outputs :

          } ]

}

and the output from the PUT :

As you can see the output from the PUT is not the same as the one from the feed i'm sending because i'm sending a end date a 13:00h and it returns an end date not modified( still at 11h45pm).

The Http response code is 200.

Anyone have a clue ?

Thanks for reading.

The error came from automatic redirection in pecl oauth http://pecl.php.net/bugs/bug.php?id=22628
