Scope
We try to provide different languages phonetic indexing methods.
- English: uses the PHP Standard Library
soundex() - German: uses a custom implementation of the Cologne phonetic indexing algorithm. https://en.wikipedia.org/wiki/Cologne_phonetics
- French: uses a custom algorithm (see below)
Installation
composer require frantzmiccoli/phphoneticindexing
Usage
use PhPhoneticIndexing\GetPhoneticIndex;
$getPhoneticIndex = new GetPhoneticIndex();
var_dump($getPhoneticIndex->getPhoneticIndex('carabine', 'fr')); // karabyn
Please note that if you wish to support new languages, those can be added using
$getPhoneticIndex->addLanguage().
