Creating a config file in PHP

Question

I want to create a config file for my PHP project, but I\'m not sure what the best way to do this is.

I have 3 ideas so far.

1-Use Variable<

Answer 1

Well - it would be sort of difficult to store your database configuration data in a database - don't ya think?

But really, this is a pretty heavily opinionated question because any style works really and it's all a matter of preference. Personally, I'd go for a configuration variable rather than constants - generally because I don't like things in the global space unless necessary. None of the functions in my codebase should be able to easily access my database password (except my database connection logic) - so I'd use it there and then likely destroy it.

Edit: to answer your comment - none of the parsing mechanisms would be the fastest (ini, json, etc) - but they're also not the parts of your application that you'd really need to focus on optimizing since the speed difference would be negligible on such small files.
