∟encodingStyle="uri" Required for rpc/encoded

This section provides a tutorial example on how to write a PHP program to call an RPC method based Web service using the SoapClient class. The Web service WSDL document has encodingStyle='uri' included.

To finish testing SoapClient class with RPC method based Web services, I wrote another SoapClient program with another Web service, GetStockPrice_WSDL_11_SOAP_11_RPC.wsdl, which has the encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" included.

Here is the example PHP program, GetStockPrice_Client.php:

<?php
# GetStockPrice_Client.php
# Copyright (c) 2007 HerongYang.com. All Rights Reserved.
#
#- Loading the WSDL document
   $server = "https://www.herongyang.com/Service/";
   $wsdl = $server . "GetStockPrice_WSDL_11_SOAP_11_RPC.wsdl";
   $client = new SoapClient($wsdl,
      array('trace' => TRUE));

#- Calling the RPC method
   $result = $client->GetStockPrice('GOOG', 'NASDAQ', '2007-07-07');

#- Showing the result
   print "Stock price is: $result\n";

#- Showing the request and response
   print $client->__getLastRequest()."\n";
   print $client->__getLastResponse()."\n";
?>

Notice that: array('trace' => TRUE) is added as an option to allow me to use __getLastRequest() and __getLastResponse() methods.

Execution result of this example is presented below:

herong> \local\php\php GetStockPrice_Client.php
Stock price is: 552.16

<?xml version="1.0" encoding="UTF-8"?>

       <stockPart xsi:type="xsd:string">GOOG</stockPart>
       <marketPart xsi:type="xsd:string">NASDAQ</marketPart>
       <datePart xsi:type="xsd:date">2007-07-07</datePart>
     </SOAP-ENV:GetStockPrice>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

<soapenv:Envelope
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:hy="https://www.herongyang.com/Service/">
  <soapenv:Header/>
  <soapenv:Body>
    <hy:GetStockPriceResponse
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
      <pricePart xsi:type="xsd:decimal">552.16</pricePart>
    </hy:GetStockPriceResponse>
  </soapenv:Body>
</soapenv:Envelope>

Notice that:

SoapClient completely ignored my namespace https://www.herongyang.com/Service/. It put the SOAP Body element GetStockPrice under the SOAP namespace.
SoapClient respected by parameter part order defined by the "soap:body[@parts]" attribute in the WSDL document.
