$xml_post_string = '<?xml version="1.0" encoding="utf-8"?>

</soapenv:Envelope>'; // data from the form, e.g. some ID number
$headers = array(
"Content-type: text/xml;charset=\"utf-8\"",
"Accept: text/xml",
"Cache-Control: no-cache",
"Pragma: no-cache"
"SOAPAction: http://testapi.roombookpro.com/en/soap/index#getCountries",
"Content-length: ".strlen($xml_post_string),
); //SOAPAction: your op URL
$url = $soapUrl;
// PHP cURL for https connection with auth
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, $soapUser.":".$soapPassword); // username and password - declared at the top of the doc
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); // the SOAP request
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
// converting
$response = curl_exec($ch);
curl_close($ch);
// converting
$response1 = str_replace("<soap:Body>","",$response);
$response2 = str_replace("</soap:Body>","",$response1);
// convertingc to XML
$parser = simplexml_load_string($response2);
var_dump($parser);
echo $parser;
// user $parser to get your data out of XML response and to display it.

Answer 1

In your code,your request is pointing to wsdl link below,
http://testapi.roombookpro.com/en/soap/index?wsdl
and thats why you are not getting soap response rather you getting the definitions.
you should use the following soap url to get the soap response,
http://testapi.roombookpro.com/en/soap/index
EDIT:
and to get the XML response (as string):
$response = curl_exec($ch);
curl_close($ch);
print_r($response);
to get as SimpleXMLElement Object :
$xml = simplexml_load_string($response);
foreach ($xml->xpath('//ns2:Soap_Model_SOAP_Location_Country') as $item)
{
print_r($item);
//to access individual elements
// echo $item->id ;
// echo $item ->code;
// echo $item->name;
// echo "\n";
}
which gives array of XML objects:
SimpleXMLElement Object
(
[id] => 252
[code] => ZW
[name] => Zimbabwe
)
