Is it possible to use inline comments for .ini files with PHP?

Question

Is it possible and safe to use inline comments for .ini files with PHP?

I prefer a system where the comments are inline with the variables, coming after them.

Answer 1

INI format uses semicolon as a comment character. It accepts them anywhere in the file.

key1=value
; this is a comment
key2=value ; this is a comment too
