Zend Framework 2 抽象工厂正在打印部分类代码 - zend framework 2 abstract factory is printing part of the class code

我是ZF2的新手。我试图复制一本 learnzf.com 书中谈论抽象工厂的例子。当我尝试将服务配置为 AbstractFactoryInterface 时，ZF2 打印类的部分代码作为结果并抛出类似 .

模块配置.php

    <?php
return array(
    'controllers' => array(
        'invokables' => array(
            'Debug'Controller'Skeleton' => 'Debug'Controller'SkeletonController',
        ),
    ),
    'router' => array(
        'routes' => array(
            'debug' => array(
                'type'    => 'Literal',
                'options' => array(
                    // Change this to something specific to your module
                    'route'    => '/skeleton',
                    'defaults' => array(
                        // Change this value to reflect the namespace in which
                        // the controllers for your module are found
                        '__NAMESPACE__' => 'Debug'Controller',
                        'controller'    => 'Skeleton',
                        'action'        => 'index',
                    ),
                ),
                'may_terminate' => true,
                'child_routes' => array(
                    // This route is a sane default when developing a module;
                    // as you solidify the routes for your module, however,
                    // you may want to remove it and replace it with more
                    // specific routes.
                    'default' => array(
                        'type'    => 'Segment',
                        'options' => array(
                            'route'    => '/[:controller[/:action]]',
                            'constraints' => array(
                                'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
                                'action'     => '[a-zA-Z][a-zA-Z0-9_-]*',
                            ),
                            'defaults' => array(
                            ),
                        ),
                    ),
                ),
            ),
        ),
    ),
    'view_manager' => array(
        'template_path_stack' => array(
            'Debug' => __DIR__ . '/../view',
        ),
    ),
    'service_manager' => array(
        'abstract_factories' => array(
            'Debug'Service'Factory'TimerAbstractFactory',
        ),
    ),
    'timers' => array(
        'timer' => array(
            'times_as_float' => true,
        ),
        'timer_non_float' => array(
            'times_as_float' => false,
        ),
    ),
);

TimerAbstractFactory.php

<?
namespace Debug'Service'Factory;
use Zend'ServiceManager'AbstractFactoryInterface;
use Zend'ServiceManager'ServiceLocatorInterface;
use Debug'Service'Timer as TimerService;
class TimerAbstractFactory implements AbstractFactoryInterface{
    protected $configKey = 'timers';
    public function canCreateServiceWithName(ServiceLocatorInterface $services,$name,$requestedName){
        $devuelve = false;  
        $config = $services->get('config');
        if(!empty($config)){
            $devuelve = isset($config[$this->configKey][$requestedName]);
        }
        return $devuelve;
    }
    public function createServiceWithName(ServiceLocatorInterface $services,$name,$requestedName){
        $config = $services -> get('config');
        $timer = new TimerService($config[$this->configKey][$requestedName]['times_as_float']);
        return $timer;
    }
}

结果（我可以在 http://localhost:8085 中看到）：

<body>
get('config');
        if(!empty($config)){
            $devuelve = isset($config[$this-&gt;configKey][$requestedName]);
        }
        return $devuelve;
    }
    public function createServiceWithName(ServiceLocatorInterface $services,$name,$requestedName){
        $config = $services -&gt; get('config');
        $timer = new TimerService($config[$this-&gt;configKey][$requestedName]['times_as_float']);
        return $timer;
    }

TimerAbstractFactory.php开头的<?应该<?php，除非您启用了短标记。
