README

Language picker that supports translation files in a directory and multi-language strings that are made programmatically (e.g. retrieved from a database or configuration file). It supports the Accept-Language header, including its more arcane uses, such as excluding languages by giving them a lower quality score than the catch-all wildcard.

Basic usage

Create translation files in a separate directory, see the directories in tests/fyrkat/multilang for an example.

<?php
$translator = new \fyrkat\multilang\TranslationContext(
	userLocale: $_COOKIE['lang'],
	localeDirectory: '../locale',
);

The localeDirectory must contain files such as en-GB.json.

Now when you want to translate a string:

<?php
$text = 'This text must be translated';
echo $translator->translate( $text );

In an HTML document, you should use this instead, so that the language is correct marked if translations are missing:

<?php
echo "<html lang=\"{$translator->primaryLocale}\">"; // e.g. nl or nl-NL
echo $translator->translateHtml('Hello'); // Hallo
echo "\n";
echo $translator->translateHtml('How are you'); // <span lang="en">How are you</span>

Multi-language fields in application data

If you have multi-language entities in your application, you can use the MultiLanguageString within your application.

<?php
$blogpostTitle1 = new \fyrkat\multilang\MultiLanguageString([
	'en-GB' => 'My first blogpost',
	'nl-NL' => 'Mijn eerste blogpost',
]);

$blogpostTitle2 = new \fyrkat\multilang\MultiLanguageString([
	'en-GB' => 'My second blogpost',
]);

These MultiLanguageStrings can be translated the same way as a normal string. They are not looked up in the locale directory, instead the most appropriate translation is chosen from the available translations.

<?php
echo "<html lang="{$translator->primaryLocale}">"; // e.g. nl or nl-NL
echo '<h1>';
echo $translator->translateHtml($blogpostTitle1); // Mijn eerste blogpost
echo '</h1>';
// more code goes here
echo '<h1>';
echo $translator->translateHtml($blogpostTitle2); // <span lang="en-GB">My second blogpost</span>
echo '</h1>';

Reporting the locale

If you are not creating an HTML document, but you still want to report the locale to the user, you can do that like this:

<?php
$text = 'This text must be translated';
$locale = null; // this is the language the text was translated into
$translated = $translator->translate( $text, $locale ); // this sets $translated and $locale
echo $locale; // nl-NL
echo ': ';
echo $translated; // Deze tekst moet vertaald worden

Listing supported languages

If you want to allow the user to choose a language, overriding the Accept-Language header

<ul>
<?php foreach($translator->getSupportedLocales() as $displayName => $locale): ?>
	<?php $locale->is($translator->primaryLocale)): ?>
		<li><strong><?= $displayName ?></strong></li>
	<?php else: ?>
		<li><a href="?lang=<?= $locale ?>"><?= $displayName ?></a></li>
	<?php endif; ?>
<?php endforeach; ?>
</ul>

Alternatively, if you want to present the user a list of languages displayed in the current language, use $translator->getSupportedLocalesWithCurrentLocale() instead. This is recommended if the language choice won't change the display language, for example setting the language tag for a blog post.
