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

@richsage is correct (for Symfony 3.?) but it did not work for my Symfony 4.x. So here is for Symfony 4.

in services.yaml file

parameters:
    param1: 'hello'

Services:
    App\Service\routineCheck:
            arguments:
                $toBechecked: '%param1%'  # argument must match in class constructor

in your service class routineCheck.php file do constructor like so

private $toBechecked;

public function __construct($toBechecked)
{
    $this->toBechecked = $toBechecked;
}

public function echoSomething()
{
    echo $this->toBechecked;
}

Done.
