How to have an array in a parameter file?

Question

I'm using Symfony2.1 and I need to save an array in a config/parameter file because I would modify the content of this array often (probably once every 6 months) (it contains email addresses).

I know that I can save a string in parameters.yml for example using :

in app/config/parameters.yml

parameters
    address: 'example@domain.com'

and retrieving this parameter using $this->container->getParameter('address') in a controller, but I have many recipients and I would like to have something like :

    parameters
        address: array('example@domain.com', 'example2@domain.com', 'example3@domain.com)
#the number of addresses is actually not defined

Answer 1

Yaml syntax for arrays would be:

address: 
    - example@domain.com
    - example2@domain.com
    - example3@domain

or

address: ["example1@domain.com", "example2@domain.com"]

but i dont know if symfony supports this.
