I think it was called "Securing Php Applications"

Hi Michele,

I hope you enjoy the book. :-)

The recommendation you're referring to is probably to reduce risk  
wherever possible. For resources that don't need to be directly  
accessible via URL, there's no reason to keep them in document root.  
But, to be clear, the risk in this case is human error.

> It also, cleared up my concerns about keeping passwords in php.

I hope this isn't bad news, but if you're on a shared host, there's  
another concern here. Others can potentially access your files, even  
if they're not in document root. I think the book discusses this in  
Chapter 8. I have a free article that might also be helpful:

I remember the discussion, and I don't believe you were attacked. Just  
be a little more honest with your uncertainty when presenting  
information. In your case, you were presenting misinformation as if it  
were fact, and people understandably corrected that. I can understand  
how this can make you feel attacked, but hopefully you can step back  
and see the bigger picture now. :-)

Exactly. If you can architect a system in a way that makes human error  
less likely or less damaging, then doing so is a good idea. Everyone  
will agree with that.

Do you remember the new book? I'd like to read it.

Nice to know. Thanks very much.
