This is a highly trimmed down version of the NuSOAP client.

The previous version is a rewrite of SOAPx4, provided by NuSphere and Dietrich Ayala. It is a set of PHP classes - no PHP extensions required - that allow developers to create and consume web services based on SOAP 1.1, WSDL 1.1 and HTTP 1.0/1.1. Here we are maintaining a version that is compatible with PHP 5.3. All the API's remain unchanged so this code is backward compatible with previous NuSOAP versions.
