I find the configuration file lacking such feature as arrays (or I don't know how to do it).
What do you think about using toml instead:
Using the PHP Provider, you can easily use arrays. Are you using the INI provider?
This is a configuration using arrays: https://github.com/phalcon/forum/blob/master/app/config/config.php
Thank you for the help!
I like the ini file - it is the way a configuration file should look like (i.e. human readable) and it will be great if it has all the required features.
