Symfony coding standards - arguments and parameters
I think that when array values are used as options (have the meaning of), in general.
For example in forms:
public function getDefaultOptions(array $options){ return array( 'validation_groups' => array('registration') );}In your bundle configuration:
class Configuration implements ConfigurationInterface{ public function getConfigTreeBuilder() { $treeBuilder = new TreeBuilder(); $rootNode = $treeBuilder->root('acme_hello'); $rootNode ->children() ->scalarNode('my_type')->defaultValue('bar')->end() ->end(); return $treeBuilder; }}In container parameters:
# app/config/config.ymlparameters: my_mailer.class: Acme\HelloBundle\Mailer my_mailer.transport: sendmailservices: my_mailer: class: "%my_mailer.class%" arguments: ["%my_mailer.transport%"]
