translit

translit is a PHP library to convert text from one script to another. Currently it assume conversion of Cyrillic, Georgian, Armenian and Greek scripts into Roman (Latin). Cyrillic has sub-groups for Russian, Ukrainian, Belarusian, Bulgarian and Kazakh languages with custom rules.

Installation

This package can be installed through Composer:

$ composer require ashtokalo/php-translit

Make sure to use Composer's autoload:

require __DIR__.'/../vendor/autoload.php';

Usage

Main class Translit could be used as singleton or object itself. Built-in transliteration tables could be referred by following language codes:

  • ru - Russian cyrillic chars,
  • uk - Ukrainian cyrillic chars,
  • mk - Macedonian cyrillic chars,
  • be - Belarusian cyrillic chars (converted to latin with diacritical),
  • bg - Bulgarian cyrillic chars (converted to latin with diacritical),
  • kk - Kazakh cyrillic chars (converted to latin with diacritical),
  • ka - Georgian chars,
  • hy - Armenian chars (converted to latin with diacritical),
  • el - Greek chars (converted to latin with diacritical),
  • cyrillic - all cyrillic chars according to ISO 9:1995,
  • latin - only latin chars without diacritical marks,
  • ascii - only ASCII chars, all non ASCII will be replaced with question mark.

Language codes could be combined by comma to handle more cases, e.g.

echo \ashtokalo\translit\Translit::object()->convert('Беларусь', 'be') . ' vs ' .
    \ashtokalo\translit\Translit::object()->convert('Беларусь', 'be,latin');

produce output:

Bielaruś vs Bielarus

You can also add alternative transliteration tables through property classes, which is list of language code in keys and class names in values:

$translit = new \ashtokalo\translit\Translit;
$translit->classes['tlh'] = \startrek\TranslitKlingon::class;
echo $translit->convert(' ', 'tlh');

By default wrong language codes ignored. But this behavior could be changed by using strict mode. For all language codes that prepended with exclamation mark exception will be fired if any error (no conversion table, wrong format, empty). For example:

// following code returns 'Привет' as is because handler ru_ru not defined
echo Translit::object()->convert('Привет', 'ru_ru') . PHP_EOL;

// but next code fires Exception, because strict mode have used
echo Translit::object()->convert('Привет', '!ru_ru') . PHP_EOL;

Tests

The package contains integration tests. You can run them using PHPUnit.

$ vendor/bin/phpunit

Credits

All transliteration tables were created from information found at Wikipedia. The links to these pages posted into header of each file. Please update me if any mistakes found or you have new transliteration tables to add here.

There are many sources of these tables which could be used - ISO and BGN/PCGN standards, a lot of native standards and informal standard used by people. For this library I assume next order of sources - native, ISO, BGN/PCGN, informal.
