I am trying to use this webservice

<?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>
    <ABRSearchByName xmlns="http://abr.business.gov.au/ABRXMLSearch/">

      </externalNameSearch>
      <authenticationGuid>string</authenticationGuid>
    </ABRSearchByName>
  </soap:Body>
</soap:Envelope>

below is my class definition

class abnlookup extends SoapClient{

    private $guid = "00000000"; 

    public function __construct($guid)
    {
        $this->guid = $guid;
        $params = array(
            'soap_version' => SOAP_1_1,
            'exceptions' => true,
            'trace' => 1,
            'cache_wsdl' => WSDL_CACHE_NONE
        ); 

        parent::__construct('http://abr.business.gov.au/abrxmlsearch/ABRXMLSearch.asmx?WSDL', $params);
    }

        public function searchByName($name){
            $params = new stdClass();
            $params->name= $name;
            $params->nameType= 'Y' ;
            $params->postcode= 'Y';
            $params->stateCode= 'N' ;           
    $params->authenticationGuid         = $this->guid;
                return $this->ABRSearchByName($params);
}  

---

call and create class object $abnlookup = new abnlookup($abn_guid); $result = $abnlookup->searchByName($name);

and recieve this msg Server was unable to process request. ---> Object reference not set to an instance of an object.second

Answer 1

The $params structure you are passing to ABRSearchByName is not correct. According to WSDL this structure has two fields (as shown by __getTypes()):

struct ABRSearchByName {
 ExternalRequestNameSearch externalNameSearch;
 string authenticationGuid;
}

Create your $params with these two fields and the problem should be resolved.
