Internationalization with Phalcon i18n

Internationalization is the process of designing and developing software that can be adapted to different languages and regions. Phalcon i18n provides a simple yet powerful way to implement internationalization in your Phalcon PHP application. In this tutorial, we will learn how to use Phalcon i18n to create a multilingual web application.

Syntax

The syntax for using Phalcon i18n in your Phalcon PHP application is as follows:

$t = $this->getDI()->getShared('translate');
echo $t->_('welcome_message');

Example

Consider the following example where we want to display a localized welcome message in English and Spanish:

  1. Create a new directory called messages in your project's app directory.
  2. Create two subdirectories in the messages directory called en and es for English and Spanish translations respectively.
  3. Create two ini files, one for each language, containing translations for the welcome message.

English Translation (app/messages/en/messages.ini):

welcome_message = Welcome to our website!

Spanish Translation (app/messages/es/messages.ini):

welcome_message = ¡Bienvenidos a nuestro sitio web!
  1. In your controller, use the translate service to load the appropriate translations based on the user's preferred language.
public function indexAction()
{
    // Set the locale based on the user's preferred language
    $locale = $this->request->getBestLanguage();

    // Load the translations for the selected locale
    $this->view->setVar('translate', $this->getService('translate')->setLocale($locale));

    // Render the view
    $this->view->pick('index/index');
}
  1. In your view, use the _() method to display the localized welcome message.
<div class="welcome-message">
    <?php echo $translate->_('welcome_message'); ?>
</div>

Explanation

In the example above, we create a directory called messages in the app directory of our Phalcon PHP application. We then create two subdirectories in the messages directory for the English and Spanish translations, respectively, and create ini files containing translations for the welcome message in each language.

In the controller, we use the translate service to determine the user's preferred language and load the appropriate translations. We then pass the translations to the view and use the _() method to display the localized welcome message.
