Obviously, your implied > argument that this is needed to implement libraries is wrong. My argument is that some functionality similar to a C #ifdef and #ifndef is needed. Neither the include_once() nor the if/endif solutions provide that. If you want to do that Perl style with packages or C style with macros or whatever style, it's fine with me. My issue is that there is no PHP way to do this other than include_once() or an if/endif statement. > Actually, even now it can be done properly, given: > 1.

You place the responsiblity of knowing the inner workings of function libraries on the user themselves and not the library.

But, if you truly believe that it needs to be more than a hacky solution, then drop this include_once() nonsense and let's think of a better way to do this. Unless of course, I'm mistaken and you are more worried about doing something hacky in the PHP source and don't care if the PHP developers themselves have to write hacky code?
