Re: [PHP-DEV] C++ extensions and ext_skel
The only modified file is ext_skel. There's also the addition of a file in ext/skeleton -- skeleton.cpp to go along with skeleton.c. I suppose I could get rid of the .cpp file, make a few changes to skeleton.c and have ext_skel make the proper modifications when it's replacing extname, EXTNAME and whatnot. The changes to config.m4 and Makefile.in are done in ext_skel.

I think that would be quite cool, save me from having to do it manualy. Shane J Smith wrote: A couple of times a month, I get questions about from people looking to use C++ with PHP.

RE: [PHP-DEV] C++ extensions and ext_skel
The door has always been open, as it has always been possible. For instance, the qtdom extension has some C++ components, as does the dotnet extension. This just sort of facilitates the, uh, moving through said door. If you're using ANSI/ISO-compliant (or mostly compliant) C and C++ compilers, like the gcc suite or MSVC++, there shouldn't be any problems. (Famous last words, I know.) I get at least two emails a week about this sort of thing, so clearly there is interest. It seems that everyone who emails me is looking to do it on either a personal basis or for some proprietary extension, so it's not like PHP itself would suddenly become polluted with C++.

Re: [PHP-DEV] C++ extensions and ext_skel
I concur, that would be cool. Patches should be against HEAD.

RE: [PHP-DEV] C++ extensions and ext_skel
Well, Personally I don't have any problem with introducing C++ into PHP so no argument there from me. I'm curious if using C++ as opposed to C would cause a performace hit?

Re: [PHP-DEV] C++ extensions and ext_skel
There is nothing about using a C++ compiler that makes your code less efficient. The primary determinant is still overwhelmingly the programmer. C++ has *never* gotten in my way when writing extremely efficient programs, and in fact I find it a great help. The flip side is I've seen a lot of hideously inefficient C code. You can write inefficient code in any language. Keep in mind that PHP is a (usually) compile-at-runtime, interpreted language :).
