Thanks for reading! This is still a young project with room for improvement and new sections. I’m already planning some content for building web pages, database access and package management with Composer. I wrote an announcement post over on dev.to if you want to read more about how the site was built: https://dev.to/restoreddev/announcing-php-apprentice-coc
I started with foundational concepts which will overlap some with the official docs. The advantage of my site is I wanted it to be more readable, since the official docs can be hard to navigate. In the future, I want to cover topics like Composer and Slim which would not be appropriate for PHP.net.
