README

PHP library for localization application.

Install

1. Run in terminal:

   composer require ddrv/translator:^2
   

2. Include autoload file

   require_once 'vendor/autoload.php';

Usage

1. Prepare translations

<?php
# /path/to/translations/default/en_US.php

return [
    'test' => 'It is test!',
    'hello' => 'Hello, %name%',
    'count' => '%count% element|%count% elements|{0}no elements',
    'interval' => '[-Inf,0[negative|[0,Inf]positive',
    'multi' => [
        'level' => [
            'key' => 'It is key in multilevel array.',
        ],
    ],
];

<?php
# /path/to/translations/default/ru_RU.php

return [
    'test' => 'Это тест!',
    'hello' => 'Привет, %name%',
    'count' => '%count% элемент|%count% элемента|%count% элементов|{0}элементов нет',
    'interval' => '[-Inf,0[отрицательное|[0,Inf]положительное',
    'multi' => [
        'level' => [
            'key' => 'Это ключ в многоуровневом массиве.',
        ],
    ],
];

1. Init library

<?php

use Ddrv\Translator\Loader\FileLoader;
use Ddrv\Translator\Provider\TranslationProvider;
use Ddrv\Translator\Translator;

// Create a loader instance. 
$loader = new FileLoader('/path/to/translations');

$translations = new TranslationProvider($loader);

$translator = new Translator('en_US', $translations);

1. Use it!

<?php

use Ddrv\Translator\Translator;

/** @var Translator $translator */
$translator->trans('default:test'); // It is test!
$translator->trans('default:multi.level.key'); // It is key in multilevel array.
$translator->trans('default:test', [], 'ru_RU'); // Это тест!

$translator->setLocale('ru_RU');
$translator->trans('default:test'); // Это тест!
$translator->trans('default:multi.level.key'); // Это ключ в многоуровневом массиве.

1. Parameters

<?php

use Ddrv\Translator\Translator;

/** @var Translator $translator */
$translator->trans('default:hello', ['name' => 'Ivan']); // Hello, Ivan!
$translator->trans('default:hello', ['name' => 'John']); // Hello, John!

1. Pluralization

<?php

use Ddrv\Translator\Translator;

/** @var Translator $translator */
$translator->trans('default:count', ['count' => 1]); // 1 element!
$translator->trans('default:count', ['count' => 2]); // 2 elements!

$translator->trans('default:interval', ['count' => -2]); // negative
$translator->trans('default:interval', ['count' => 2]); // positive

You can develop your loader that implements the \Ddrv\Translator\Contract\DomainLoader interface.

You can use multiple loaders at once

<?php

use Ddrv\Translator\Contract\DomainLoader;
use Ddrv\Translator\Provider\TranslationProvider;
use Ddrv\Translator\Loader\MultiLoader;
use Ddrv\Translator\Translator;

/**
 * @var DomainLoader $loader1
 * @var DomainLoader $loader2
 * @var DomainLoader $loader3
 */
$loader = new MultiLoader($loader1);
$loader->addLoader($loader2);
$loader->addLoader($loader3);

$translations = new TranslationProvider($loader);

$translator = new Translator('en_US', $translations);

You may wrap your loader to \Ddrv\Translator\Loader\CachedLoader

<?php

use Ddrv\Translator\Contract\DomainLoader;
use Ddrv\Translator\Provider\TranslationProvider;
use Ddrv\Translator\Loader\CachedLoader;
use Ddrv\Translator\Translator;
use Psr\SimpleCache\CacheInterface;

/**
 * @var DomainLoader $loader
 * @var CacheInterface $cache
 */
$cached = new CachedLoader($loader, $cache, 'loader_1_');

$translations = new TranslationProvider($cached);

$translator = new Translator('en_US', $translations);
