Mogę zadzwonićcurl_setopt zCURLOPT_HTTPHEADER wiele razy, aby ustawić wiele nagłówków?

$url = 'http://www.example.com/';

$curlHandle = curl_init($url);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, array('Content-type: application/xml'));
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, array('Authorization: gfhjui'));

$execResult = curl_exec($curlHandle);
