Will PHP return an error if I have a call to an undefined function but that code branch is not run?

In good old compiled languages like C++ you are not allowed to do that.
I would think that it is an approach to be disrecommended - such things
are not a part of the language definition (I assume) so even if it works
now - the PHP-developer team might change it without notice, especially
if they later were to make a "compiler" for php3.

But - why not just write an empty function now and replace it later if
you need? Your code would work just the same - and you are on the safe
side! You can always use 'require' and 'include' to control which files
containing functions that are loaded.
