This is a simple class to load and give translated strings, for localization.

It was formerly used in the Jelix Framework.

installation

You can install it from Composer. In your project:

composer require "jelix/simplelocalization"

Usage

First create lang files. You can store strings of all lang into a single file, or in one file per lang. Each file is a PHP array, and each strings have a key.

Example. Here is a file translation.en.php for english strings:

<?php

return array(
    'welcome' => 'Hello world',
    'thank.you' => 'Thank you'
);

Now translation.fr.php for french strings:

<?php

return array(
    'welcome' => 'Bonjour le monde',
    'thank.you' => 'Merci'
);

Or if you choose to have a single file translation.php :

<?php

return array(
    'en' => array(
        'welcome' => 'Hello world',
        'thank.you' => 'Thank you'
    ),
    'fr' => array(
        'welcome' => 'Bonjour le monde',
        'thank.you' => 'Merci'
    )
);

Now in your PHP code, instanciate a container:

// with multiple files
$locales = new \Jelix\SimpleLocalization\Container('translation.%LANG%.php');
// note that %LANG% in the path will be replace by a lang code

// with a single file
$locales = new \Jelix\SimpleLocalization\Container('translation.php');

// with an array of file name. You can mix path with `%LANG%` tag and path without it
$locales = new \Jelix\SimpleLocalization\Container(array('translation.%LANG%.php', 'other_translation.php'));


// with an array of strings
$locales = new \Jelix\SimpleLocalization\Container(array(
    'en' => array(
        'welcome' => 'Bonjour le monde',
        'thank.you' => 'Merci'
    ),
    'fr' => array(
        'welcome' => 'Bonjour le monde',
        'thank.you' => 'Merci'
    )
));

As second parameter to the constructor, you can give a lang code. If not given the current lang will be guessed from $_SERVER['HTTP_ACCEPT_LANGUAGE'];

Now, to retrieve a string from its key:

$str = $locales->get('welcome');

That's it...
