This section describes the SOAP protocol and PHP implementations of SOAP. PEAR::Package::SOAP, NuSOAP, and php_soap.dll (from the PHP Group) seems to be 3 different SOAP implementations.

What Is SOAP Module? - SOAP (Simple Object Access Protocol) Module, also called SOAP Extension, allows you to create and call Web services using the SOAP protocol. SOAP Module was introduced in PHP 5.

PHP SOAP extension is included in the PHP distribution package as shown below on my Windows system:
