Configuration 如何从Zend Framework 2中布局/视图脚本中的自动加载配置文件访问配置？

我想/必须在中管理一些设置，并为视图提供有关当前环境的信息

/config/application.config.php

return array(
    ...
    'module_listener_options' => array(
        ...
        'config_glob_paths' => array('config/autoload/{,*.}{global,local}.php')
    )
);

return array(
    // allowed values: development, staging, live
    'environment' => 'development'
);

return array(
    ...
    'module_listener_options' => array(
        ...
        'config_glob_paths' => array('config/autoload/{,*.}{global,local}.php')
    )
);

return array(
    // allowed values: development, staging, live
    'environment' => 'development'
);

/config/autoload/env.local.php

return array(
    ...
    'module_listener_options' => array(
        ...
        'config_glob_paths' => array('config/autoload/{,*.}{global,local}.php')
    )
);

return array(
    // allowed values: development, staging, live
    'environment' => 'development'
);

return array(
    ...
    'module_listener_options' => array(
        ...
        'config_glob_paths' => array('config/autoload/{,*.}{global,local}.php')
    )
);

return array(
    // allowed values: development, staging, live
    'environment' => 'development'
);

在公共视图脚本中，我可以通过控制器执行此操作，因为控制器可以访问服务管理器以及我需要的所有配置：

class MyController extends AbstractActionController {

    public function myAction() {
        return new ViewModel(array(
            'currentEnvironment' => $this->getServiceLocator()->get('Config')['environment'],
        ));
    }

}

也可以直接在公共视图中获取配置吗

如何访问布局视图脚本（

/module/Application/view/layout/layout.phtml

）中的配置？（我的实现/解释）：

我建议使用一个注入了配置的视图帮助器，在我刚才给出的答案->中用config替换模型类，并使用你的帮助器作为代理，当然是@Crisp提供的方法，但是对于为什么你真的需要它们，会有强烈的疑问。一个视图应该呈现，没有别的，它甚至不应该为任何单个配置而烦恼。这就是管制员的工作。你到底想做什么？你当然可以使用这两种方法，但我倾向于按照Sam的建议将其排除在视图之外：）@Sam我想允许在开发/登台环境中显示web analytics JS。这绝对是viewHelper

displayAnalytics（）的解决方案

-viewHelper将通过ServiceManager访问配置，然后输出空字符串或功能分析代码。参见crisp提供的答案；）
