SWIG didn't support function overloading for PHP until very recently, so
in 0.9.2, you have to use WritableDatabase_delete_document_by_term to
say that the 2nd argument is a term not a docid.  The next release will
be generated with a newer version of SWIG where such renaming is no
longer required.

So the error you have is because the bindings try to parse 'extid:1367'
as a number and fail so get 0, then try to delete docid 0, which Xapian
throws an error for.
