Problem testing PUT parameter value with Slim

I do not quite understand how this happens with the variables PUT and Slim.

Please consider the following route:

$app->put('/users/me',function() use ($app){
    $app->response->headers->set('Content-Type', 'application/json');
    $userData = $app->request()->put();
    var_dump($userData);
});

This route basically accepts a PUT request and returns all variables with it. When I test it with curl, it works as expected:

oris@oris:~/slim-api$ curl -i -H "Accept: application/json" -X PUT -d "hello=there" http://slim-api.com/users/me
HTTP/1.1 200 OK
Server: nginx/1.2.1
Date: Thu, 06 Feb 2014 09:53:11 GMT
Content-Type: application/json
Transfer-Encoding: chunked
Connection: keep-alive
X-Powered-By: PHP/5.4.6-1ubuntu1.5

Pragma: no-cache

array(1) {
    ["hello"]=>
    string(5) "there"
}

I wrote a small PHPUnit test for this route using this bootstrap.php file :

 public function testPutUsersMe()
{
    $this->put('/users/me',array("myKey=myValue"));
    $userResponse = $this->response->body();
    var_dump($userResponse);
}

I also added a tiny addition to this boot file to update superglobals for every request:

//sets php super globals so other packages would have access to them on tests context
public function setRequestGlobals($method,$path,$options = array())
{
    $_SERVER['REQUEST_METHOD'] = $method;
    if (!empty($options)){
        if ($method === "GET"){
            foreach($options as $key => $value){
                $_GET[$key] = $value;
            }
        }
        if ($method === "POST"){
            foreach($options as $key => $value){
                $_POST[$key] = $value;
            }
        }
        if ($method === "PUT"){
            foreach($options as $key => $value){
                $_POST[$key] = $value;
            }
        }
    }

}

I call $this->setRequestGlobals($method,$path,$options);inside the method request. But this brings up the following answer, which is not quite right:
