Oh no, you are exactly right. Well, kind of.

Using exit() in the append file results in the append file never being
appended.

But think about a prepend file. If you use die or exit anywhere, the
rest of the script is killed. That means whatever you prepended a file
into.

Exactly. Not to mention your coding guidelines and or application
structure should dictate how all includes are handled.

One example is testing for a given variable. For example, I prepend a
file called reset.php to certain session applications. To make sure
that is available in an easy sense, I simply throw "$reset = true;" at
the end of it.

Then I can just if ($reset) { // don't reinclude } or something similar.

Current bugs? Most of the ones I knew about were solved in the later
versions of PHP 4 and surely now by 5.

Please do. Make sure to post them as well.

If they helped, you are quite welcome!
