What version of PHP are we talking about? In its early days, it was very expensive, particularly if your code-base grew very large... Later, it was only expensive if your client was doing something whack like dynamically including hundreds of file snippets. (Don't ask.) These days, I would hazard a guess that it's as optimized as it can be, really, but you'd have to test and read source to be sure. Note that in all cases, the performance issue kicked in when you were including LOTS of different files, as the search space for what was already included grew. -- Some people have a "gift" link here.
