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

One simple but elegant way is to create a config.php file (or whatever you call it) that just returns an array:

 'localhost',
    'username' => 'root',
);

And then:

$configs = include('config.php');
