I've seen PHP run on a lot of systems, from System i to Raspberry > Pi, and on all kinds of OSes C compiler runs on.

"Officially support" would be "if feature X doesn't work or gracefully degrade in all these places, it will not be accepted". Of course, almost anything *can* be made to run almost anywhere, but that does not mean it is supported. "Supported" means that the PHP project is prepared to actively maintain current and future compatibility with it. This doesn't mean that you can't make it work on platform X, only that it's not guaranteed that you can. For example, raspberry pi is probably not one of those places that would be officially supported. PHP is used heavily in commercial settings, so the way to compile the list is probably to look at what people are actually using on a commercial scale and use that list. Suppot can also be dropped for ancient operating systems when it is reasonable (such as when a new feature is blocked by that OS but a newer version provides the means to implement it), as happened with win XP etc. This would obviously only apply to the core, PECL extensions would be free to support what they like.
