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.
The config file should contain parameters for the app itself and for the registered extensions/services.
Example:
// 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?
First of all, add the Symfony Yaml component to your composer.json
"symfony/yaml": "2.1.*@dev",
Use the right version choosing directly from the packagist page: 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:
"deralex/yaml-config-service-provider": "1.0.x-dev"
Here the official github page: https://github.com/deralex/YamlConfigServiceProvider
Here the packagist page: https://packagist.org/packages/deralex/yaml-config-service-provider
UPDATE
Install the dependencies with ./composer.phar update
command and finally add these lines to your app file:
$app = new Silex\Application();
$app->register(new DerAlex\Silex\YamlConfigServiceProvider(__DIR__ . '/settings.yml'));
Now, for example, you can do this:
settings.yml
database:
driver: pdo_mysql
host: localhost
dbname: database_name
user: root
password: password
charset: utf8
index.php
$app->register(new Silex\Provider\DoctrineServiceProvider(), array(
'db.options' => $app['config']['database']
));
