Php &引用；网络错误：500内部服务器错误-http://localhost/cc/client"

我使用rpc库与客户机和服务器通信，下面是我的代码

<?php

class ClientController extends Zend_Controller_Action
{

    public function init()
    {
        /* Initialize action controller here */
    }

    public function indexAction()
    {
        // action body
         echo "Hello you are in index";

        $client = new Zend_XmlRpc_Client('Server url');

        //var_dump($client);

        try {
            echo "cf doesent called";
            $data = $client->call('cf.test'); 

            $this->view->data = $data;
        } catch (Zend_XmlRpc_Client_HttpException $e) {
            require_once 'Zend/Exception.php';
            throw new Zend_Exception($e);
        } catch (Zend_XmlRpc_Client_FaultException $e) {
            require_once 'Zend/Exception.php';
                throw new Zend_Exception($e);
        }
    }
}

class ServerController extends Zend_Controller_Action
{

    public function init()
    {
        /* Initialize action controller here */
    }

    public function indexAction()
    {
        // action body
        $this->_helper->viewRenderer->setNoRender();
        $server = new Zend_XmlRpc_Server();
        $server->setClass('Application_Model_Data', 'cf');
        echo $server->handle();
    }
}



<?php

class Application_Model_Data
{
    /**
     * Test method
     *
     * @return string
     */
    public function test()
    {
        return 'Hello XMLRPC!';
    }
}

检查日志或激活错误报告（如果尚未执行）。这个错误几乎可以是所有的错误。在php错误日志中，我没有检查任何东西。。
