New PECL Proposal: Double Metaphone

Hello again, I would like to propose a new PECL package which provides Double Metaphone Capability. For those who are not aware of what this is, it allows a word to be broken down into phonemes. The Double Metaphone is an amelioration of the Metaphone algorithm which gives better results with languages other than English. We use it here to process French and it gives better results than the original Metaphone (which is already present in PHP core, thanks to Thies). If you look in comments from the Metaphone function of the Manual, you can see an implementation in PHP of the Double Metaphone algo. While this can work, it is really slow. This is what motivated us to move it at the C level. The package uses the C library written by Maurice Aubrey, available at CPAN. It is available under the Artistic License, which to my understanding is compatible with PHP. As for the name, I do not know if it should be "doublemetaphone" or "double_metaphone". It would be filled under category Text. Sincerely, Olivier
