I have a .env file that is being parsed by both PHP and node Node implementations.

I'm asking here in the canonical repo, as this is more of a best practice question.

I have values that have literal dollar signs in them:

DB_PASS=DgaH$a43

Should I be quoting that, or escaping the dollar?
If I escape the dollar in my .env file, will I need to unescape it when i use it?

So I guess it boils down to - should I be escaping the dollar in my .env file, or when I get the value with PHP or Node or whatever?
