Xapian discuss - Jun 2007 - php5 new_BM25Weight() function error

I am using PHP 5.1 and get the following error always.

[code]
$enquire->set_weighting_scheme(new XapianBM25Weight(1, 0, 1, 0, 0));

[error message]
Fatal error: No matching function for overloaded 'new_BM25Weight' in
xapian.php on line 831


I have tested with version 1.0.1 and 1.0.1_svn8976. The results are same.
And I think this error may be the same kind of thing as the following.

It works if you write:

  $enquire->set_weighting_scheme(new XapianBM25Weight(1.0, 0.0, 1.0, 0.0,
0.0));

SWIG implements overload dispatch based on the PHP type so if a C++
method takes a double, you currently have to pass a floating point value
in PHP.

Ideally it would allow and convert an integer in cases like this where
there's no overload ambiguity, since such strict type requirements
aren't natural in PHP, but currently that doesn't happen.
