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：

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

或

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 CONFIGURING PHP INI SETTINGS IN ZF2 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！
