SOAP request in PHP with CURL

Question

Since the SOAP manual on php.net is not very noob friendly and I could not find any good examples I will post my question here.

How can I create PHP SOAP request to look like this?

POST /MySERVER/myWSDLservice.asmx HTTP/1.1
Host: connection.mywebsite.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://connection.mywebsite.com/MySERVER/GetCarType"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
 <soap:Body>
  <GetCarType xmlns="http://connection.mywebsite.com/MySERVER/">
    <IDNumber>string</IDNumber>
  </GetCarType>
 </soap:Body>
</soap:Envelope>

Please note:

• there is user/pass auth
• SSL connection

Any suggestion / links / example much appreciated.

          <?php 
          //Data, connection, auth
          $dataFromTheForm = $_POST['fieldName']; // request data from the form
          $soapUrl = "https://connecting.website.com/soap.asmx?op=DoSomething"; // asmx URL of WSDL
          $soapUser = "username";  //  username
          $soapPassword = "password"; // password
  
          // xml post structure
  
          $xml_post_string = '<?xml version="1.0" encoding="utf-8"?>
                              <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
                                <soap:Body>
                                  <GetItemPrice xmlns="http://connecting.website.com/WSDL_Service"> // xmlns value to be set to your's WSDL URL
                                    <PRICE>'.$dataFromTheForm.'</PRICE> 
                                  </GetItemPrice >
                                </soap:Body>
                              </soap:Envelope>';   // data from the form, e.g. some ID number
  
             $headers = array(
                          "Content-type: text/xml;charset=\"utf-8\"",
                          "Accept: text/xml",

                      ); //SOAPAction: your op URL
  
              $url = $soapUrl;
  
              // PHP cURL  for https connection with auth
              $ch = curl_init();
              curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);

              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);
              // user $parser to get your data out of XML response and to display it.
