Debugging SOAP requests

If for some reason you have to deal with debugging on SOAP requests (that is, to see the actual request and response bodies), you can use these methods:

• SoapClient::__getLastRequest()
• SoapClient::__getLastRequestHeaders()
• SoapClient::__getLastResponse()
• SoapClient::__getLastResponseHeaders()

and remember to set the trace option when initializing the SOAP object. For example, using the free webservicex.net:

<?php
// initialize soap client
$soap = new SoapClient(
    "http://www.webservicex.net/country.asmx?WSDL", [
    "trace" => true,
]);

// call a method on soap object
$soap->__call("getCountries", [
    // options for method
]);

// output raw request, something like
// <?xml version="1.0" encoding="UTF-8"?>
// <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
//                    xmlns:ns1="http://www.webserviceX.NET">
//     <SOAP-ENV:Body>
//         <ns1:GetCountries/>
//     </SOAP-ENV:Body>
// </SOAP-ENV:Envelope>
echo $soap->__getLastRequest(); 

// output raw response, something like
// <?xml version="1.0" encoding="utf-8"?>
// <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
//                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
//                xmlns:xsd="http://www.w3.org/2001/XMLSchema">
//     <soap:Body>
//         <GetCountriesResponse xmlns="http://www.webserviceX.NET">
//             <GetCountriesResult>
//                 <!-- ... -->
//             </GetCountriesResult>
//         </GetCountriesResponse>
//     </soap:Body>
// </soap:Envelope>
echo $soap->__getLastResponse();
