Description:
------------
There's a problem with objects' class name received by soap server, when passed in request object is inheriting from other one. For example:
data type definition in wsdl:
<xsd:complexType name="Vehicle">
 <xsd:all>
  <xsd:element name="loadWeight" type="xsd:int"></xsd:element>
 </xsd:all>
</xsd:complexType>

<xsd:complexType name="Car">
 <xsd:complexContent>
  <xsd:extension base="tns:Vehicle">
   <xsd:all>
    <xsd:element name="engineNumber" type="xsd:string"></xsd:element>
   </xsd:all>
  </xsd:extension>
 </xsd:complexContent>
</xsd:complexType>

Second object is inheriting from the first one. And we have operation defined like that:
<wsdl:message name="addCarResponse">
 <wsdl:part name="return" type="tns:Car"></wsdl:part>
</wsdl:message>
<wsdl:message name="addCarRequest">
 <wsdl:part name="car" type="tns:Car"></wsdl:part>
</wsdl:message>

<wsdl:operation name="addCar">
 <soap:operation soapAction="http://www.foo.com/VehicleService/addCar"/>
  <wsdl:input>
   <soap:body use="encoded" namespace="http://www.foo.com/VehicleService/" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
  </wsdl:input>
  <wsdl:output><soap:body use="encoded" namespace="http://www.foo.com/VehicleService/" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
  </wsdl:output>
</wsdl:operation>

Soap client is written in Java (axis). Method addCar is invoked with variable of type Car. Soap server (PHP5) receives proper structure of object - it has all fields, inherited from father and it's own, but get_class(passedObject) returns father's class name (Vehicle). Class mapping is correct. WSDL file is correct. Even returned object, also of type Car, is correct. 

Reproduce code:
---------------
$classmap = array( 'Car' => 'Car', 'Vehicle' => 'Vehicle' );
class fooService {
 public addCar($car) {
  $fh = fopen("foo.txt","a+"); fwrite($fh,get_class($car)+"\n"); fwrite($fh,var_export($car,true)); fclose($fh);
  $storedObject = $this->storeInDB($car);
  return $storedObject;
 }
ini_set('soap.wsdl_cache_enabled',"0");
$server = new SoapServer('fooService.wsdl',array('classmap' => $classmap');
$server->setClass(fooService);
$server->handle();

Expected result:
----------------
File content:
Car
Car: loadWeight->someValue
Car: engineNumber->someOtherValue

Actual result:
--------------
File content:
Vehicle
Vehicle: loadWeight->someValue
Vehicle: engineNumber->someOtherValue

I have a little bit to add to this bug, I think I am experiencing it as well. There are two outcomes, depending if you add the base class to the classmap or not: 

If the base class IS in the classmap it gives the error "Cannot instantiate abstract class IProduct"; when I take away the xs:extension and paste the fields from IProduct to Product within the WSDL the problem goes away. So it is as if it's trying to instantiate the base class, as it is doing to the other person experiencing this bug.

If the base class is NOT in the classmap (but the subclass still is), it returns the result as a stdClass.

My WSDL schema is as follows:

 <xs:complexType name="IProduct">
    <xs:all>
     ...
    </xs:all>
 </xs:complexType>
 <xs:complexType name="Product">
 	 <xs:complexContent>
		<xs:extension base="tns:IProduct"> 
		    <xs:all>
		     ...
		    </xs:all>
	    </xs:extension> 
    </xs:complexContent>
 </xs:complexType>

Message:
    <message name="getProduct-response">
        <part name="result" type="types:Product"/>
    </message>

PHP classes:
abstract class IProduct {
    ...
}
class Product extends IProduct {
    ...
}

Classmap (shared by client and server):
array( 
    ...
    "IProduct" => "IProduct",
    "Product" => "Product"
);


Thanks,
Harlan Iverson

The same as #36575 (Incorrect complex type instantiation with hierarchies).
