How to create a PHP SOAP Request and Response

Question

I am working with an API and I am new to PHP SOAP.. I am trying to create a request to get a vehicle value and am looking to get the response value.

The following is a sample SOAP 1.1 request. The placeholders shown need to be replaced with actual values.

POST /vehicles/vehicle.asmx HTTP/1.1
Host: webservice.nada.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://webservice.nada.com/getDefaultVehicleAndValueByVin"

<?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>
    <getDefaultVehicleAndValueByVin xmlns="http://webservice.nada.com/">
    <vehicleRequest>
    <Vin>string</Vin>
    <Region>int</Region>
    <Mileage>int</Mileage>
  </vehicleRequest>
</getDefaultVehicleAndValueByVin>

Here is the SOAP Client URL Call -

 $clientV = new soapclient('http://webservice.nada.com/vehicles/vehicle.asmx?wsdl',array(
// Stuff for development. 'trace' => 1,'exceptions' => 1, 'cache_wsdl' => 0));

This is what ive tried but get no result -

$clientV = new soapclient('http://webservice.nada.com/vehicles/vehicle.asmx?wsdl',array(// Stuff for development. 'trace' => 1,'exceptions' => 1, 'cache_wsdl' => 0));

 $params = new \SoapVar("<vehicleRequest><Vin>5YFBURHE3FP331896</Vin><Region>10</Region><Mileage>100000</Mileage></vehicleRequest>", XSD_ANYXML);
 $result = $client->Echo($params);

Another method I tried but get error parsing WSDL

$wsdl = '
POST /vehicles/vehicle.asmx HTTP/1.1
Host: webservice.nada.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://webservice.nada.com/getDefaultVehicleAndValueByVin"
<?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>
    <getDefaultVehicleAndValueByVin xmlns="http://webservice.nada.com/">
      <vehicleRequest>
        <Vin>5YFBURHE3FP331896</Vin>
        <Region>1</Region>
        <Mileage>100</Mileage>
      </vehicleRequest>
    </getDefaultVehicleAndValueByVin>
  </soap:Body>
</soap:Envelope>
';

try {

     $clientC = @new SOAPClient($wsdl);  for $wsdl

     $response = $clientC->getDefaultVehicleAndValueByVin(array('key' => 'val')); 

     } catch (Exception $e) {  

     echo $e->getMessage(); 

}

die(var_dump($response));

Here is the error I get -

SOAP-ERROR: Parsing WSDL: Couldn't load from ' POST /vehicles/vehicle.asmx HTTP/1.1 Host: webservice.nada.com Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://webservice.nada.com/vehicles/vehicle.asmx?wsdl" 5YFBURHE3FP331896 1 100 ' : failed to load external entity " POST /vehicles/vehicle.asmx HTTP/1.1 Host: webservice.nada.com Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://webservice.nada.com/vehicles/vehicle.asmx?wsdl"

What are the specific problems you are facing? What have you tried so far? I'm afraid SO is neither a "What is the best tutorial" nor a "please write me some code" service - as you for sure know already. Given your previous questions you have enough php skills to give it a try! — Jeff

Yes Im not looking for someone to write the code for me..Im looking for how to structure the XML Call in a php script. Using that SOAP URL call im not sure how to include the XML call. Again ive never used SOAP so just looking for some direction or starting point — Ryan D

I updated the question with my attempt but it doesn't return any result. Do I need to add all the XML into the $params? — Ryan D

What you are assigning to the variable $wsdl is not a WSDL document, it is an HTTP request. You need to load a proper WSDL doc. — Brian Driscoll

@BrianDriscoll thanks, I found this as an example where they had the $wsdl as the xml data. I am struggling to find a way to request that xml data in the php script — Ryan D

Something like this should help you get started. I am not 100% familiar with the NADA API so I don't know what valid values are for some of the parameters... you'll have to fill in the correct values (e.g. for Token, Period, VehicleType, and Region).

$clientV = new SoapClient('http://webservice.nada.com/vehicles/vehicle.asmx?wsdl',array('trace' => 1,'exceptions' => 1, 'cache_wsdl' => 0));

$params = new stdClass();
$params->Token = '';
$params->Period = 1;
$params->VehicleType = '';
$params->Vin = '5YFBURHE3FP331896';
$params->Region = 1;
$params->Mileage = 100;

$result = $clientV->getDefaultVehicleAndValueByVin(array('vehicleRequest' => $params));
