$settings array or Config Class to store project settings?

Question

How should I store settings for project?

Which is better - to use a $settings array with all my settings:

$settings[\'max_photos\'] = 30;
//         


        

Answer 1

If the project settings is too heavy, then file(xml is better) is good and a dedicated class for settings is also good.

If the project settings is small, then array is best, its very fast and no I/O related issue will arise.

Even you can use database (slower and auth issue).
