How to access an application parameters from a service?

by

You can pass parameters to your service in the same way as you inject other services, by specifying them in your service definition. For example, in YAML:

services:
    my_service:
        class:  My\Bundle\Service\MyService
        arguments: [%my_param1%, %my_param2%]

where the %my_param1% etc corresponds to a parameter named my_param1. Then your service class constructor could then be:

public function __construct($myParam1, $myParam2)
{
    // ...
}
