I want to have a bunch of settings in my module, and they should be writable from the App. Since they're application settings, I thought a table for it would be not very efficient (it would only have one row).
I found the Zend module Zend\Config, which seems to be able to to write config files, which can in turn be used by Zend.
It is advisable to write into the module.config.php? Or into a different file? Can I still load it into the standard module config?
I am pretty new to Zend and this fully modular approach, so I'd like some clarification on that.
You should never write into the module directory itself. Instead, have a data directory, e.g. at the root of your application, and put written configuration files in there.
