(PHP Extension) Making SOAP Requests using the REST API

There's no reason a SOAP request cannot be sent using the REST API. It's only a matter of adding a SOAP specific header, and providing the SOAP XML request body. The response body is the SOAP response XML.

This example sends a request to ws.cdyne.com to get city weather by zip code.

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// Demonstrates how to do a SOAP request using the REST API.

// 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 is the request to be sent:

// POST /WeatherWS/Weather.asmx HTTP/1.1
// Host: wsf.cdyne.com

// Content-Length: length
// SOAPAction: "http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP"
