There is, of course, a performance hit, in that PHP searches for your include file in each of those paths before it finds "the one" Depending on server configuration, caching, and hardware, that could be immesurably small for 6 or 7 paths, or it could be a Big Deal. Only you can test on your hardware with your setup. But I would dare to predict that for most users, the performance difference is negligible because you are almost for sure not including enough files to be causing enough operations for it to matter. Sure, you can construct a benchmark to "prove" that there is a performance difference. But can you construct a real-world test with peak load usage similar to real users that shows a meaningful difference? Cuz you don't really care about a benchmark about a billion includes when your web app never does a billion includes... If you have a directory that has "most" of the includes in it, put it first, of course -- Surely that would be easy enough to do, and would address any performance issue "well enough" for a real world setup. Another option is to MAYBE consider combining some of those dirs, and using a filename convention to make it clear which ones are model and which are controller and which are library. And, of course, if you are using a cache, then the search through include_path is only done once per cache-fault. -- Some people have a "gift" link here. Know what I want?
