This service provider for Silex 2.0 uses the Yaml classes from Symfony to provide a config service to a Silex application, and other service providers.

Add euskadi31/config-service-provider to your composer.json:

% php composer.phar require euskadi31/config-service-provider:~1.0

<?php

$env = getenv('APP_ENV') ?: 'prod';

$app = new Silex\Application;

$app->register(new \Euskadi31\Silex\Provider\ConfigServiceProvider(
    __DIR__ . '/config/' . $env . '.yml'
));

Now you can specify a prod and a dev environment.

config/prod.yml

debug: false

config/dev.yml

debug: true

To switch between them, just set the APP_ENV environment variable. In apache that would be:

SetEnv APP_ENV dev

Or in nginx with fcgi:

fastcgi_param APP_ENV dev

Also, you can pass an array of replacement patterns as second argument.

<?php

$app = new Silex\Application;

$app->register(new \Euskadi31\Silex\Provider\ConfigServiceProvider(
    __DIR__ . '/config/services.yml',
    [
        'data_path' => __DIR__ . '/data'
    ]
));

Now you can use the pattern in your configuration file.

/config/services.yml

xsl.path: %data_path%/xsl

You can also specify replacements inside the config file by using a key with %foo% notation:

%root_path%: ../..,
xsl.path: %root_path%/xsl

Make sure you register ConfigServiceProvider last with your application. If you do not do this, the default values of other Providers will override your configuration.
