∟Call WSDL Operation with SoapClient::__soapCall()

This section provides a tutorial example on how to call an operation defined in a WSDL document using the __soapCall(operation_name,...) function.

Instead of calling the WSDL operation as a SoapClient object function, you can also invoke the WSDL operation with the SoapClient::__soapCall() function:

Get the URL of the Web service WSDL document.
Identify the operation in the WSDL document you want to call.
Identify input parameters required by the operation.
Create a SoapClient object with URL of the WSDL document.
Call the __soapCall() function on the SoapClient object with the operation name provided as the first argument.
Provide input parameters as an associated array, wrap it in another array and then provided to __soapCall() as the second argument.
Dump the result of the call as an object.

Here a good example of a client program, NumberConversionCallSoap.php, on how to call an WSDL operation with the SoapClient::__soapCall() function. The NumberConversion Web service and its WSDL document are provided by dataaccess.com.

<?php 
# NumberConversionSoapCall.php
# Copyright (c) 2007 HerongYang.com. All Rights Reserved.
#
   $client = new SoapClient
("https://www.dataaccess.com/webservicesserver/numberconversion.wso?WSDL");
   $operation = "NumberToWords";
   $inputs = array('ubiNum'=>202);
   $args = array($inputs);
   $result = $client->__soapCall($operation, $args);

   echo("Operation: $operation\n");
   echo("Arguments:\n");
   var_dump($args);
   echo("Result:\n");
   var_dump($result);
?>

When running it, I am getting:

herong> php NumberConversion.php

Operation: NumberToWords

Arguments:
array(1) {
  [0]=>
  array(1) {
    ["ubiNum"]=>
    int(202)
  }
}

Result:
object(stdClass)#2 (1) {
  ["NumberToWordsResult"]=>
  string(20) "two hundred and two "
}
