Zend http

PHP
1

Using Zend/Http and cURL I want to create a function that depending whether I pass $data to function or not it uses get or post way. I used this:

function Post_Curl_Data ($url, $data = ‘’, $header = ‘’) {

    $options = array(CURLOPT_RETURNTRANSFER => 1);
    if (!empty($data)) {
        $options += array(CURLOPT_POST => 1, CURLOPT_POSTFIELDS => $data);
     }


    if (!empty($header)) {
        $options += array(CURLOPT_HTTPHEADER => $header);
    }

    $config = array(
                    'adapter'   => 'Zend\\Http\\Client\\Adapter\\Curl',
                    'curloptions' => $options
             );


    $client = new Zend\\Http\\Client($url, $config);
    $response = $client->send();
     return trim($response->getContent());

}

It works fine with get method, but actually does not post $data to url however I did set: CURLOPT_POST => 1 and CURLOPT_POSTFIELDS => $data
Plz advice what wrong I did?
