What is a Zend Soap Server?

Zend\Soap\Server class is intended to simplify Web Services server part development for PHP programmers.

It may be used in WSDL or non-WSDL mode, and using classes or functions to define Web Service API.

When Zend\Soap\Server component works in the WSDL mode, it uses already prepared WSDL document to define server object behavior and transport layer options.

WSDL document may be auto-generated with functionality provided by Zend\Soap\AutoDiscovery component or should be constructed manually using Zend\Soap\Wsdl class or any other XML generating tool.
