Where do I learn about CodeIgniter core (I mean the 'system' folder)? - castle - 02-28-2019

Hey,

I'm wondering if there is any documentation about CI core itself. Any information architecture, flowcharts or something that gives a glimpse of how the CI works under the hood.

Thanks

The closest thing is the application flow chart in the user guide.There was talk, a few years back, of building a more formal writeup on the CodeIgniter internals. That effort fizzled, from lack of available manpower. The driving file is system/core/CodeIgniter.php.

CodeIgniter 4, for all of its relatve richness, has a similar problem.  The core service mechanism is described in the user guide, and Lonnie Ezell has written a number of blog posts which would be relevant, but there is no architecture document. The driving file is system/CodeIgniter.php.

Thank you. Too bad that there's nothing out there.

I found the best way was to sit down and go through the CodeIgniter core code.
There are lots of little hidden gems in the code.
