I've not tried it myself, but I believe SWIG does support wrapping
an extension which builds on another extension like this.

Just include <xapian.h> in user code - the other headers are an
implementation detail and might get renamed, merged, split, etc.

Yes, SWIG doesn't parse included files by default, and the %include
tells it to.

I'm not sure I understand what you mean.  You are wanting a class which
wraps a C++ class, which is what a 'proxy' class is - a PHP class which
forwards its methods to a C++ class,
