Zend Framework 2 时区设置警告问题的解决

按照 Zend 官方文档安装了 Zend Framework，启动之后的默认页显示了如下警告：

Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'UTC' for '8.0/no DST' instead in E:\clbx.cn\module\Application\view\layout\layout.phtml on line 44

虽然可以通过 php 的设置屏蔽警告，或者直接在 php.ini 文件中设置 date.timezone，又或者在 index.php 文件中添加如下语句：

1 ini_set('date.timezone', 'Asia/Shanghai');

或

1 date_default_timezone_set('Asia/Shanghai');

不过我是个配置强迫症患者：尽可能的不动系统设置，并且利用配置文件来完成这样的工作，是我的目标。

当然，此类问题优先要找一找有没有现成的解决方案，百度一番，没有结果，还是 google 给力，在  找到了如下一段代码：

<?php
 namespace PhpSettings;

 use Zend\EventManager\Event;

 class Module
 {
     /**
      * Configure PHP ini settings on the bootstrap event
      * @param Event $e
      */
     public function onBootstrap(Event $e) {
         $app = $e->getParam('application');
         $config = $app->getConfiguration();
         $phpSettings = $config['phpSettings'];
         if($phpSettings) {
             foreach($phpSettings as $key => $value) {
                 ini_set($key, $value);
             }
         }
     }

     /* The getAutoloaderConfig() and getConfig() methods are left out here
        for brevity, as they are completely standard.
      */
 }

并在配置文件中添加了如下设置：

return array(
     'phpSettings' => array(
         'display_startup_errors' => false,
         'display_errors' => false,
         'max_execution_time' => 60,
         'date.timezone' => 'Europe/London',
         'mbstring.internal_encoding' => 'UTF-8',
     ),
 );

不过上面明确说明，这个只适用于 Zend Framework 2 Beta4，我用的是 Zend Framework 2 2.1.5 正式版，有了一些变化。

首先，这个类的命名空间是 Application，而且其中 onBootstrap 方法已经有了内容。

不管它，先粘过来再说，当然也得讲点规矩，别将代码直接粘到 onBootstrap中，代码如下：

<?php
 namespace Application;

 use Zend\Mvc\ModuleRouteListener;
 use Zend\Mvc\MvcEvent;

 class Module
 {
     public function onBootstrap(MvcEvent $e)
     {
         $e->getApplication()->getServiceManager()->get('translator');
         $eventManager = $e->getApplication()->getEventManager();
         $moduleRouteListener = new ModuleRouteListener();
         $moduleRouteListener->attach($eventManager);
         $this->setPhpSettings($e);
     }


     private function setPhpSettings(MvcEvent $e)
     {
         $config = $e->getApplication()->getConfiguration();
         if (array_key_exists('phpSettings'], $config) && is_array($config['phpSettings'])) {
             foreach ($config['phpSettings'] as $key => $value) {
                 ini_set($key, $value);
             }
         }
     }

     public function getConfig()
     {
         return include __DIR__ . '/config/module.config.php';
     }

     public function getAutoloaderConfig()
     {
         return array(
             'Zend\Loader\StandardAutoloader' => array(
                 'namespaces' => array(
                     __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
                 ),
             ),
         );
     }
 }

没有配置项放在作者所说的文件里，而是放在了项目根目录下 confit/autoload 的 local.php 文件中（将 local.php.dist 改名为 local.php）。

浏览，问题依旧。

仔细翻看 ZF2 源代码，发现，没有 getConfiguration 方法，取而代之的是 getConfig 方法，修改代码：

<?php
 namespace Application;

 use Zend\Mvc\ModuleRouteListener;
 use Zend\Mvc\MvcEvent;

 class Module
 {
     public function onBootstrap(MvcEvent $e)
     {
         $e->getApplication()->getServiceManager()->get('translator');
         $eventManager = $e->getApplication()->getEventManager();
         $moduleRouteListener = new ModuleRouteListener();
         $moduleRouteListener->attach($eventManager);
         $this->setPhpSettings($e);
     }


     private function setPhpSettings(MvcEvent $e)
     {
         $config = $e->getApplication()->getConfig();
         if ($config['phpSettings']) {
             foreach ($config['phpSettings'] as $key => $value) {
                 ini_set($key, $value);
             }
         }
     }

     public function getConfig()
     {
         return include __DIR__ . '/config/module.config.php';
     }

     public function getAutoloaderConfig()
     {
         return array(
             'Zend\Loader\StandardAutoloader' => array(
                 'namespaces' => array(
                     __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
                 ),
             ),
         );
     }
 }

浏览，问题解决！
