[Phpmyadmin-devel] header.inc.php3 safty net

[jeremy brand]

Hi Marc,

Personally, I never use require().. I've only used require because that
seemed to be the norm in phpMyAdmin.

So, in my thinking, everywhere I wrote require, it should have been an
include (that is just how my brain works).

Anyhow..  I don't fully understand phpMyAdmin because I have not spent the
effort to.

I have stong feelings about the include-require issue.  It was so long ago
that I came to a conclusion (that being that I don't use require in my
projects and only use include), that it didn't even occur to me here.

Jeremy
