What I've done is actually moved my ebook library store onto my web server and access have a shared drive mapped to it from the PC and I've set Calibre to use that path directly thereby any changes I make in Calibre are immediately available on my web interface.

Being very new to PHP I appreciate your comments.
I store the variables in the session to have them available to each .PHP without having to pass them in the URL to keep them from the user browsing, seems like a good idea unless there's a better way (still keeping them invisible to the browser).

Not sure what the "MVC architecture" is yet , I was trying to make this be dependent on as little as possible as some people were talking of wanting a PHP interface for use on their NAS box and I figured there probably won't be too many nice modules etc available.

Do you perhaps have an example of using "parametrized queries"? Again, not sure what you mean yet

Thanks again for your comments. There's still a lot to be done and part of that I'll probably be moving some of the code in the main .php into functions in calibre2php.inc.php.
