How to access an application parameters from a service?

Question

From my controllers, I access the application parameters (those in /app/config) with

$this->container->getParameter(\'my_param\')
<         


        

Answer 1

As solution to some of issues mentioned, I define an array parameter then inject it. Adding a new parameter later just requires addition to parameter array without any change to service_container arguments or construct.

So extending on @richsage answer:

parameters.yml

parameters:
    array_param_name:
        param_name_1:   "value"
        param_name_2:   "value"

services.yml

services:
    my_service:
        class:  My\Bundle\Service\MyService
        arguments: [%array_param_name%]

Then access inside class

public function __construct($params)
{
    $this->param1 = array_key_exists('param_name_1',$params)
        ? $params['param_name_1'] : null;
    // ...
}
