Since count is a MySQL reserved keyword, we use cnt as the name of the column carrying the count

The @ character suppresses error messages - https://www.php.net/…rcontrol.php. I'm not sure why we decided to use it here, it should work without it as well.

why is there no lesson on active record? Or it is discussed in another topic?

Active record is no standard way how to handle data and it's often considered an antipattern, you can try googling "activerecord antipattern" - https://www.google.com/search?…

It's an interesting topic to write about, but I don't think it's a must-have stuff. I'll write it down and try to bring something about that in the future.
