SoapVar Constructor - Creating Encoded Values

This section provides a tutorial example on how to create input parameters with type encoded values. Built-in types are XSD_STRING, XSD_BOOLEAN, XSD_DECIMAL, XSD_DATE, XSD_ANYXML, etc.

In the previous tutorial, I tried to specify input parameter names with the SoapParam constructor. It did not work because my WSDL document has parameter names explicitly defined.

In this tutorial, I want test the SoapVar constructor, which can be used to encode strings into SOAP values:

   $value = new SoapVar($string, encoding);

"encoding" should be one of predefined constants like: XSD_STRING, XSD_BOOLEAN, XSD_DECIMAL, XSD_DATETIME, XSD_TIME, XSD_DATE, XSD_ANYURI, XSD_ANYXML, etc.

Here is my testing tutorial program, SoapClient_SoapVar.php:

<?php 
# SoapClient_SoapVar.php
# Copyright (c) 2009 HerongYang.com, All Rights Reserved.
#
#- Loading the WSDL document
   $server = "http://www.herongyang.com/Service/";
   $wsdl = $server . "GetStockPrice_WSDL_11_SOAP_11_RPC.wsdl";
   $client = new SoapClient($wsdl,
      array('trace' => TRUE));

#- Test 1: Calling with values directly
   $result = $client->GetStockPrice('GOOG', 'NASDAQ', '2007-07-07');
   print $client->__getLastRequest()."\n";

#- Test 2: Calling with SoapVal objects correct encoding types
   $stock = new SoapVar("GOOG", XSD_STRING);
   $market = new SoapVar("NASDAQ", XSD_STRING);
   $date = new SoapVar("2007-07-07", XSD_DATE);
   $result = $client->GetStockPrice($stock, $market, $date);
   print $client->__getLastRequest()."\n";

#- Test 3: Calling with SoapVal objects with incorrect encoding types
   $stock = new SoapVar("<Stock>GOOG</Stock>", XSD_STRING);
   $market = new SoapVar("<Market>NASDAQ</Market>", XSD_ANYXML);
   $date = new SoapVar("2007-07-07", XSD_DATETIME);
   $result = $client->GetStockPrice($stock, $market, $date);
   print $client->__getLastRequest()."\n";
?>

Here is the result of this tutorial program:

<SOAP-ENV:Envelope ...">
  <SOAP-ENV:Body>
    <SOAP-ENV:GetStockPrice>
      <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>

<SOAP-ENV:Envelope ...">
  <SOAP-ENV:Body>
    <SOAP-ENV:GetStockPrice>
      <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>

<SOAP-ENV:Envelope ...">
  <SOAP-ENV:Body>
    <SOAP-ENV:GetStockPrice>
      <stockPart xsi:type="xsd:string">&lt;Stock&gt;GOOG
        &lt;/Stock&gt;</stockPart>
      <Market>NASDAQ</Market>
      <datePart xsi:type="xsd:dateTime">2007-07-07</datePart>
    </SOAP-ENV:GetStockPrice>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

This result is very interesting:
