Symfony bootstrap文件，我的意思是所有其他文件包含的文件

Question

我想在我的Symfony项目中全局做一些事情，例如我想打电话

mb_internal_encoding("UTF-8");

在Symfony中，正确的地方在哪里？我知道有web / app.php和web / app_dev.php，但这些是两个文件，我相信必须有一个文件，我可以做到这一点。

对于任何代码的全局加载，在Symfony 2中添加的最佳位置是app / AppKernel.php。在AppKernel.php或使用的类语句下添加代码。

use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

date_default_timezone_set( 'Asia/Kolkata' );
 mb_internal_encoding("UTF-8");
class AppKernel extends Kernel
{


    public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new Bvi\AdminBundle\BviAdminBundle(),
            new Bvi\UserBundle\BviUserBundle(),
            new FOS\UserBundle\FOSUserBundle(),
            new Kap\ContactBundle\KapContactBundle(),
            new Bvi\ApiBundle\BviApiBundle(),
            new WhiteOctober\TCPDFBundle\WhiteOctoberTCPDFBundle(),
            new Knp\Bundle\PaginatorBundle\KnpPaginatorBundle(),
        );

        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
            $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
        }

        return $bundles;
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
    }
}
