Answer 1

From Symfony 4.1 inside Service

    private $params;
    public function __construct(ParameterBagInterface $params)
    {
        $this->params = $params;
    }
    public function check($e)
    {
       if($this->params->get("kernel.environment") === "dev") 
       {
            return true;
       }
    }
}

Answer 2

To get the current environment in a Controller you can use:

$this->container->getParameter('kernel.environment');

So you just put that in an if() statement to check if it equals to dev.

Answer 3

For Symfony 4.x and above

If you are using .env to store your environment variables, you can access them in any controller by simply using $_ENV['name-of-variable']

For a default installation, there is a $_ENV["APP_ENV"] variable available, which will tell you if you are in dev mode or not.

Use print_r($_ENV); to see all the available environment variables.

[ps - This also works for Symfony 3.4]
