如何在Silex Framework中使用YAML配置文件

Is it possible to configure a Silex Application with YAML config files? I bet yes, but how is it done correctly? For instance I want to use different configurations according to the environment, like config.dev.yml and config.prod.yml.

是否可以使用YAML配置文件配置Silex应用程序？我打赌是的，但它是如何正确完成的？例如，我想根据环境使用不同的配置，如config.dev.yml和config.prod.yml。

The config file should contain parameters for the app itself and for the registered extensions/services.

配置文件应包含应用程序本身和已注册扩展/服务的参数。

Example:

例：

// Debug flag should be set in the config file
$app['debug'] = true;

// Extension options should also be set in config file
$app->register(new Silex\Extension\TwigExtension(), array(
    'twig.path'       => __DIR__.'/views',
    'twig.class_path' => __DIR__.'/vendor/Twig/lib',
));

Do I have to parse the YAML file by myself and set the parameters accordingly or is there a more "magic" way to do this?

我是否必须自己解析YAML文件并相应地设置参数，还是有更“神奇”的方法来做到这一点？

First of all, add the Symfony Yaml component to your composer.json

首先，将Symfony Yaml组件添加到composer.json中

"symfony/yaml": "2.1.*@dev",

Use the right version choosing directly from the packagist page: https://packagist.org/packages/symfony/yaml

使用直接从包装页面选择正确的版本：https：//packagist.org/packages/symfony/yaml

Now, you can add the deralex YamlConfigProvider, a simple and useful Silex provider. Add it to your composer.json:

现在，您可以添加deralex YamlConfigProvider，一个简单而有用的Silex提供程序。将它添加到您的composer.json：

"deralex/yaml-config-service-provider": "1.0.x-dev"

Here the official github page: https://github.com/deralex/YamlConfigServiceProvider

这里是官方的github页面：https：//github.com/deralex/YamlConfigServiceProvider

Here the packagist page: https://packagist.org/packages/deralex/yaml-config-service-provider

这里包装页面：https：//packagist.org/packages/deralex/yaml-config-service-provider

UPDATE

UPDATE

Install the dependencies with ./composer.phar update command and finally add these lines to your app file:

使用./composer.phar update命令安装依赖项，最后将这些行添加到您的app文件中：

$app = new Silex\Application();
$app->register(new DerAlex\Silex\YamlConfigServiceProvider(__DIR__ . '/settings.yml'));

Now, for example, you can do this:

现在，例如，你可以这样做：

settings.yml

settings.yml中

database:
    driver: pdo_mysql
    host: localhost
    dbname: database_name
    user: root
    password: password
    charset: utf8

index.php

的index.php

$app->register(new Silex\Provider\DoctrineServiceProvider(), array(
    'db.options' => $app['config']['database']
));

This package in the answer does not work for Silex 2.0 that is why I've created package that works for Silex 2.0 and Symfony/Yaml 3.1. Maybe someone looking for this answer will find it useful

答案中的这个包对Silex 2.0不起作用，这就是为什么我创建了适用于Silex 2.0和Symfony / Yaml 3.1的包。也许有人在寻找这个答案会发现它很有用

https://packagist.org/packages/rpodwika/yaml-config-service-provider

to use run command

使用run命令

composer require rpodwika/yaml-config-service-provider

or add

或添加

"rpodwika/yaml-config-service-provider" : "dev-master"

to your composer.json

到你的composer.json

github link https://github.com/rpodwika/yaml-config-service-provider

github链接https://github.com/rpodwika/yaml-config-service-provider

to use:

使用：

<?php

require_once __DIR__.'/../vendor/autoload.php';

$app = new Silex\Application();

$app->register(new Rpodwika\Silex\YamlConfigServiceProvider("settings.yml"));

echo $app['config']['database']['driver'];

The LoadConfigExtension described by @fbrandel (above in comments) allows you to share the yml loader config service.

@fbrandel描述的LoadConfigExtension（在注释中）允许您共享yml loader配置服务。
