env file and boolean values ​​such as true or false

Inside the .env file, how should I deal with boolean variables?
In the original file, for example, I find variables set to true and one set to 'true'.

Code:

honeypot.hidden = 'true'

I've set my variable to both true and 'true', but it's always treated as a string.

I'm using getenv() to retrieve the value, is there maybe some other function that returns a boolean instead of a string in these cases?
