Good day comrades! In my free time I continue to write my CMS system, there were many versions of the system (about 12) and with each new version, the functionality was added and the speed increased, however, this is the problem:
The system needs to store the settings, read and use them in the main file, and read and modify them in the admin panel.
I tried to store the settings in the XML files, everything is fine, but the performance dropped noticeably.
What are the ways to store and write "settings" without using the database?
