You are right.  The problem is that SWIG/PHP doesn't support "directors"
currently, which you need to create a useful PHP subclass of
MatchDecider.  It might be unacceptably slow for a large database even
if it was supported, since it would require a call from C++ to PHP for
every document which matches the query (up to the limit of 1000000 or
whatever).

I described an alternative approach which could be implemented in PHP
here:
