Challenge #1 of 1

Q: 

Suppose you're using a fictional OrderPizzaBundle, which requires you to put an API key to their service/API in a config file (where abcd1234 is our real API key for this example):

order_pizza:
    api_key: 'abcd1234'

A developer on your team recommends changing this to:

order_pizza:
    api_key: '%env(PIZZA_API_KEY)%'

Is this a good recommendation? Why or why not?

a)

It is a good recommendation. Then, you should set the value of the new PIZZA_API_KEY environment variable in .env or .env.local.

b)

It is a good recommendation, but you first need to check the documentation of the OrderPizzaBundle to see what the name of the environment variable should be - i.e. is PIZZA_API_KEY correct?

c)

This is a good recommendation... just the wrong syntax! It should be `api_key: '%getenv(PIZZA_API_KEY)%'

d)

This is only a good recommendation if your production environment is capable of storing environment variables.
