Is there any info on writing your own cms?

Question

CMS

Hello, recently I have a burning desire to write something like a blog on my cms (pseudo-cms) in php.
I myself am in the back-end`e the bottom is complete. I only know the basics of php, and even then I don’t know how to use them more or less correctly and where exactly to apply them.
At the moment, something similar to what I wanted to write has already somehow turned out, but I want to somehow develop further in this regard (back-end).
So is there any info, tutorials, manuals on how to write something similar to cms in procedural php?
PS Forgiveness for such a stupid question, show indulgence to the newbie :)

Answer 1

I wrote this many years ago as my first project, the style turned out - the config file is included at the beginning, the output file at the end, between them the module file itself with the processing of controllers by switch. There are no difficulties with basic knowledge of PHP, the problems that arise are googled without problems, but apart from self-learning, this is zero sense.
BUT the first rule of writing your tsms. - Do not write your own cms

Answer 2

steal from famous tsms, you can't go wrong.
but in general the procedural approach is a bit narrower.
