Accessing a SOAP Webservice using PHP containing a complexType in the WSDL

I want to make a call to a webservice of which I only have the WSDL file. I'll list the important bits from the WSDL file with context sensitive names replaced by general ones:

The function I want to call:

<wsdl:operation name="myFunction">
   <wsdl:input message="ns:myFunctionRequest" wsaw:Action="urn:myFunction"/>
   <wsdl:output message="ns:myFunctionResponse" wsaw:Action="urn:myFunctionResponse"/>
</wsdl:operation>

The description of the function:

<xs:element name="myFunction">
   <xs:complexType>
      <xs:sequence>
         <xs:element minOccurs="0" name="param0" nillable="true" type="xs:string"/>
         <xs:element minOccurs="0" name="param1" nillable="true" type="somens:MyType"/>
         <xs:element minOccurs="0" name="param2" nillable="true" type="xs:string"/>
      </xs:sequence>
   </xs:complexType>
</xs:element>

The description of 'MyType':

<xs:complexType name="MyType">
    <xs:sequence>
        <xs:element minOccurs="0" name="date1" nillable="true" type="xs:dateTime"/>
        <xs:element minOccurs="0" name="date2" nillable="true" type="xs:dateTime"/>
        <xs:element minOccurs="0" name="string1" nillable="true" type="xs:string"/>
        <xs:element minOccurs="0" name="int1" nillable="true" type="xs:int"/>
        <xs:element minOccurs="0" name="int2" nillable="true" type="xs:int"/>
    </xs:sequence>
</xs:complexType>

I am thinking of my PHP code looking a bit like this:

$client = new SOAPClient('my soap URL');

$result = $client->setState(array('param0'=>'bla', 'param1'=><undecided>, 'param2'=>'bla');

My problem is what to put in the undecided part. Should that be an array that maps names in the complex type to values? Or should it be a class that I define myself with field of the corresponding types? I don't have a good testing ground to try this out at this moment and I would like 开发者_高级运维to be able to move on before I do have it available.

I saw a lot of SOAP related questions unanswered, so I hope I will get lucky :). If I happen to find out myself, I will of course share my results.

Thanks in advance!

In my experience, you need an object instead of an array, but stdClass will suffice, so you can just cast an array to object if it makes life easier:

$client->myFunction(
    'bla',
    (object)array(
        'date1'   => '2010-01-01 00:00:00',
        'date2'   => '2010-01-02 00:00:00',
        'string1' => 'foobar',
        'int1'    => 1,
        'int2'    => 2
    ),
    'bla');
