Installation

composer require insolita/metaphone

Usage

<?php

$word = 'вода';
$phonetic = (new Metaphone())->processWord($word); //вада

Default set of filters include filter for lastname endings, if you want exclude only these filter, you can use helper

$withLastnames = (new Metaphone())->processWord('Чернышевский'); //чирнаш#
$withoutLastnames = (new Metaphone())->skipLastnames()->processWord('Чернышевский'); //чирнашифский

Provide custom filters. Each filter must implement insolita\metaphone\Filter

$metaphone = new Metaphone([Normalize::class, new CustomFilter($params), new HandleConsonants(true), ...])
$phonetic = $metaphone->processWord($word);
