This blog post serves as excellent feedback for what beginners might get stuck on, and where I may have subconciously assumed prior knowledge.

The permissions errors essentially support ticket #3 - if we switch to PHP's built-in web server, and drop Apache for the time being, we can get away with just installing PHP and solve the permissions issues at the same time.

It seems some of the PDO material could be explained more thoroughly - what does $pdo represent? What do exec() and query() actually do? What is contained in a $stmt? I'd like to try to do this without reference to object orientation, as I think that will just muddy the waters. This stuff is complex enough as it is! 😄
