CURL不适用于SOAP封装的XML请求

I tried to get response from SOAP request using CURL but can't get any success. I got error like,

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

I used code,

$envelope = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:aut="http://schemas.tourico.com/webservices/authentication" xmlns:hot="http://tourico.com/webservices/hotelv3" xmlns:hot1="http://schemas.tourico.com/webservices/hotelv3">

                  </hot1:ChildAges>
               </hot1:RoomInfo>

</soapenv:Envelope>';

$soap_do = curl_init();

curl_setopt($soap_do, CURLOPT_URL,            "http://demo-hotelws.touricoholidays.com/hotelflow.svc?wsdl" );
curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($soap_do, CURLOPT_TIMEOUT,        10);
curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true );
curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($soap_do, CURLOPT_POST,           true );            
curl_setopt($soap_do, CURLOPT_POSTFIELDS,     $envelope); 
curl_setopt($soap_do, CURLOPT_VERBOSE, TRUE); 
curl_setopt($soap_do, CURLOPT_HTTPHEADER, array("Content-Type: text/xml","SOAPAction: \"http://demo-hotelws.touricoholidays.com/HotelFlow.svc/bas\"", "Content-length: ".strlen($envelope))); 

$result = curl_exec($soap_do);
echo "<pre>";
print_r($result);
exit;

I got response in SOAPUI software but not working with php code.

Can anyone help me to sorted out this problem?
