PHP SOAP Extension - RPC Method Based Web Services
This section provides a tutorial example on how to write a PHP program to call an RPC method based Web service with SOAP 1.2 binding using the SoapClient class. 'soap_version' => SOAP_1_2 is used for SOAP 1.2.
According to the manual, SOAP Extension in PHP 5.3.1 does support SOAP 1.2. To use the SoapClient class for SOAP 1.2 Web services, the "soap_version" option is needed when loading the WSDL document as shown in this example:
$client = new SoapClient($wsdl,array('soap_version' => SOAP_1_2));
Since my first RPC method based Web service, GetExchangeRate, has use="encoded", but no encodingStyle="uri". SOAP Extension does not like it. So I am going to test the GetStockPrice Web service.
Here is the example PHP program, GetStockPrice_SOAP12_Client.php:
<?php # GetStockPrice_SOAP12_Client.php # Copyright (c) 2009 by Dr. Herong Yang, herongyang.com # All rights reserved #- Loading the WSDL document $server = "http://www.herongyang.com/Service/"; $wsdl = $server . "GetStockPrice_WSDL_11_SOAP_12_RPC.wsdl"; $client = new SoapClient($wsdl, array('trace' => TRUE, 'soap_version' => SOAP_1_2)); #- 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"; ?>
Execution result of this example is presented below:
Stock price is: 552.16 <env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:enc="http://www.w3.org/2003/05/soap-encoding"> <env:Body> <env:GetStockPrice env:encodingStyle="http://www.w3.org/2003/05/soap-encoding"> <stockPart xsi:type="xsd:string">GOOG</stockPart> <marketPart xsi:type="xsd:string">NASDAQ</marketPart> <datePart xsi:type="xsd:date">2007-07-07</datePart> </env:GetStockPrice> </env:Body> </env:Envelope> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:ser="http://www.herongyang.com/Service/"> <soap:Header/> <soap:Body> <ser:GetStockPriceResponse soap:encodingStyle="http://www.w3.org/2003/05/soap-encoding"> <pricePart xsi:type="xsd:decimal">552.16</pricePart> </ser:GetStockPriceResponse> </soap:Body> </soap:Envelope>
Notice that SoapClient used SOAP 1.2 namespaces correctly in the SOAP request.
This confirms that SOAP Extension in PHP 5.3.1 does support RPC method based Web services defined in WSDL 1.1 with SOAP 1.2 binding.
