SOAP Web Service (HTTP POST)

Demonstrates how to call PostXml to call a SOAP web service. PHP Extension

<?php

include("chilkat.php");

$success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// --------------------------------------------------------------------------------
// Also see Chilkat's Online WSDL Code Generator
// to generate code and SOAP Request and Response XML for each operation in a WSDL.
// --------------------------------------------------------------------------------

// This example uses a live web service at:
// http://www.webservicex.net/uklocation.asmx
// It gets the UK town,Postcode and County by Postcode(First Section of Post Code)

// The SOAP XML will look like this:
// <?xml version="1.0" encoding="utf-8"?>
// <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
//   <soap:Body>
//     <GetUKLocationByPostCode xmlns="http://www.webserviceX.NET">
//       <PostCode>string</PostCode>
//     </GetUKLocationByPostCode>
//   </soap:Body>
// </soap:Envelope>

// For this example's sake, we'll load the XML from a file.  We'll test using PostCode "E3".  
// The SOAP XML for this example may be downloaded from:
// http://www.chilkatsoft.com/testData/ukPostCodeSoap.xml
$xml = new CkXml();
$success = $xml->LoadXmlFile('ukPostCodeSoap.xml');
if ($success == false) {
    print $xml->lastErrorText() . "\n";
    exit;
}

$strXml = $xml->getXml();

$http = new CkHttp();

// We'll need to add this in the HTTP header:
// SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
$http->SetRequestHeader('SOAPAction','http://www.webserviceX.NET/GetUKLocationByPostCode');

// The endpoint for this soap service is:
$endPoint = 'http://www.webservicex.net/uklocation.asmx';

// Note: This particular web service was live and functioning at the time this example
// was written.  It is possible that as time progresses, this web service will no longer
// be availble...
$resp = new CkHttpResponse();
$success = $http->HttpStr('POST',$endPoint,$strXml,'utf-8','text/xml',$resp);
if ($success == false) {
    print $http->lastErrorText() . "\n";
    exit;
}

$responseStatusCode = $resp->get_StatusCode();
// You may wish to verify that the responseStatusCode equals 200...
print 'Response Status Code: ' . $responseStatusCode . "\n";

// You may examine the exact HTTP header sent with the POST like this:
print 'LastHeader:' . "\n";
print $http->lastHeader() . "\n";

// Examine the XML returned by the web service:
print 'XML Response:' . "\n";
$xmlResp = new CkXml();
$xmlResp->LoadXml($resp->bodyStr());
print $xmlResp->getXml() . "\n";
