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

Define will make the constant available everywhere in your class without needing to use global, while the variable requires global in the class, I would use DEFINE. but again, if the db params should change during program execution you might want to stick with variable.
