A JSON/Yaml-based config ServiceProvider for Silex.

Pass the config file's path to the service provider's constructor. This is the recommended way of doing it, allowing you to define multiple environments.

$env = getenv('APP_ENV') ?: 'prod';
$app->register(new Igorw\Silex\ConfigServiceProvider(__DIR__."/../config/$env.json"));

Now you can specify a prod and a dev environment.

/config/prod.json

{
    "debug": false
}

/config/dev.json

{
    "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.

$app->register(new Igorw\Silex\ConfigServiceProvider(__DIR__."/../config/services.json", array(
    'data_path' => __DIR__.'/data',
)));

Now you can use the pattern in your configuration file.

/config/services.json

{
    "xsl.path": "%data_path%/xsl"
}

To use Yaml instead of JSON, just pass a file that ends on .yml:

$app->register(new Igorw\Silex\ConfigServiceProvider(__DIR__."/../config/services.yml"));

Note, you will have to require the 2.1.* of the symfony/yaml package.

You can use multiple config files, e. g. one for a whole application and a specific one for a task by calling $app->register() several times, each time passing another instance of Igorw\Silex\ConfigServiceProvider.
