I found the need to use multiple strategies for my WSDL strategy. This is because I had a class that was for my response which had an array of ints and I wanted that to show up instead of just array.

The default nature of this will always return something since the last strategy used is Zend_Soap_Wsdl_Strategy_AnyType

hope this is useful

class ReturnClass
{
    /**
     * @var string[]
     */
    public $firstName = array();

    /**
     * @var string[]
     */
    public $lastName = array();

    /**
     * @var string[]
     */
    public $email = array();
}

class Zend_Soap_Wsdl_Strategy_Composite
    extends Zend_Soap_Wsdl_Strategy_Abstract
{
    protected $_strategies = array(
        'Zend_Soap_Wsdl_Strategy_DefaultComplexType',
        'Zend_Soap_Wsdl_Strategy_ArrayOfTypeComplex',
        'Zend_Soap_Wsdl_Strategy_ArrayOfTypeSequence',
        'Zend_Soap_Wsdl_Strategy_AnyType',
    );

    public function __construct(array $strategies = null)
    {
        $this->setStrategies($strategies);
    }

    public function setStrategies(array $strategies = null)
    {
        if (!empty($strategies)) {
            foreach ($strategies as $strategy) {
                if (!class_exists($strategy)) {
                    require_once "Zend_Soap_Wsdl_Exception";
                    throw new Zend_Soap_Wsdl_Exception(
                        "WSDL Strategy {$strategy} does not exist"
                    );
                }
            }
            $this->_strategies = $strategies;
        }
    }

    /**
     * @param  string $type class
     * @return string XSD type for the given PHP type
     */
    public function addComplexType($type)
    {
        $retval = false;

        foreach ($this->_strategies as $strategy) {
            try {
                $strategy = new $strategy();
                $strategy->setContext($this->getContext());
                $retval = $strategy->addComplexType($type);
                break;
            } catch(Zend_Soap_Wsdl_Exception $e) {}
        }

        if(!$retval)
        {
            throw new Zend_Soap_Wsdl_Exception(
                "{$type} cannot be converted to a XSD type"
            );
        }

        return $retval;
    }
}
