Input/output datatypes are converted into network service types using the following mapping:
PHP strings <->
xsd:string.PHP integers <->
xsd:int.PHP floats and doubles <->
xsd:float.PHP booleans <->
xsd:boolean.PHP arrays <->
soap-enc:Array.PHP object <->
xsd:struct.PHP class <-> based on complex type strategy (See: this section) [29].
type[] or object[] (ie. int[]) <-> based on complex type strategy
PHP void <-> empty type.
If type is not matched to any of these types by some reason, then
xsd:anyTypeis used.
Where xsd: is "http://www.w3.org/2001/XMLSchema" namespace,
soap-enc: is a "http://schemas.xmlsoap.org/soap/encoding/" namespace,
tns: is a "target namespace" for a service.

Zend_Soap_AutoDiscover will be created with
the
Zend_Soap_Wsdl_Strategy_DefaultComplexType
class as detection algorithm for complex types. The first parameter
of the AutoDiscover constructor takes any complex type strategy
implementing
Zend_Soap_Wsdl_Strategy_Interface or a string
with the name of the class. For backwards compatibility with
$extractComplexType boolean variables are parsed
exactly like in Zend_Soap_Wsdl. See the
Zend_Soap_Wsdl
manual on adding complex types for more information.
