# Translator
[![Latest Version on Packagist][ico-version]][link-packagist]
[![Software License][ico-license]](LICENSE)
[![Total Downloads][ico-downloads]][link-downloads]
Created by Oscar Otero <http://oscarotero.com> <oom@oscarotero.com> (MIT License)
Translator functions to use with [gettext/gettext](https://github.com/php-gettext/Gettext). Useful if you don't have the native gettext extension for php or want to avoid problems with it.
## Installation
```
composer require gettext/translator
```
## Translator
```php
use Gettext\Translator;
//Create a new instance of the translator
$t = new Translator();
//Load the translations from php files (generated by Gettext\Extractors\PhpArray)
$t->loadTranslations(
'locales/gl/domain1.php',
'locales/gl/domain2.php',
'locales/gl/domain3.php',
);
//Now you can use it in your templates
echo $t->gettext('apple');
```
## GettextTranslator
The class `Gettext\GettextTranslator` uses the gettext extension. It's useful because combines the performance of using real gettext functions but with the same API than `Translator` class, so you can switch to one or other translator without change code of your app.
```php
use Gettext\GettextTranslator;
//Create a new instance
$t = new GettextTranslator();
//It detects the environment variables to set the locale, but you can change it:
$t->setLanguage('gl');
//Load the domains:
$t->loadDomain('messages', 'project/Locale');
//this means you have the file "project/Locale/gl/LC_MESSAGES/messages.po"
//Now you can use it in your templates
echo $t->gettext('apple');
```
## Translator functions
To ease the use of translations in your php templates, you can use the provided functions:
```php
use Gettext\TranslatorFunctions;
//Register the translator to use the global functions
TranslatorFunctions::register($t);
echo __('apple'); // it's the same than $t->gettext('apple');
```
You can scan the php files containing these functions and extract the values with the PhpCode extractor:
```html
<!-- index.php -->
<html>
<body>
<?= __('Hello world'); ?>
</body>
</html>
```
