The problem is that we can't legally distribute binary packages of the
PHP bindings:

http://trac.xapian.org/wiki/FAQ/PHP%20Bindings%20Package

This is rather annoying, particularly as earlier PHP versions were
dual-licensed under the GPL.  Unless someone can persuade the PHP
developers to either dual-license as GPL, or drop the pointless naming
restriction which is the cause of the incompatibility, I can only see
it getting resolved once we get to the point where we can relicense
Xapian.

The FAQ entry there also has instructions for building your own.

You can just put all the colours for an object together in a value slot
- e.g. "blue,green" - and then write a suitable subclass of MatchDecider
or a PostingSource which looks if a given colour is in that list.
Similarly for facets you can handle this with a MatchSpy subclass which
splits the list and processes each entry as a separate facet value.

"+1" doesn't really help - it needs somebody actually interested in
implementing it.  It's also still not entirely clear what the details of
an implementation would be.
