Phalcon Internationalization

Phalcon is written in C as an extension for PHP. There is a PECL (PHP Extension Community Library) extension that offers internationalization functions to PHP applications called intl. In PHP 5.4/5.5 this extension is bundled with PHP. Its documentation can be found in the pages of the official PHP manual.

Locale

There are several ways to find out the best available locale using intl. One of them is to check the HTTP Accept-Language header:

<?php

$locale = Locale::acceptFromHttp($_SERVER['HTTP_ACCEPT_LANGUAGE']);

// Locale could be something like 'en_GB' or 'en'
echo $locale;

Examples of identifiers include:

? en-US (English, United States). ? fr-CA, fr-FR (French for Canada and France respectively) etc.

Formatting messages

<?php

// Prints ? 4 560
$formatter = new MessageFormatter('fr_FR', '? {0, number, integer}');
echo $formatter->format([4560]);

// Prints USD$ 4,560.5
$formatter = new MessageFormatter('en_US', 'USD$ {0, number}');
echo $formatter->format([4560.50]);

// Prints ARS$ 1.250,25
$formatter = new MessageFormatter('es_AR', 'ARS$ {0, number}');
echo $formatter->format([1250.25]);

Example

<?php

use Phalcon\Mvc\Controller;

class UsersController extends Controller
{
    public function registerAction()
    {
        $user = new Users();
 $formatter = new MessageFormatter('fr_FR', '$user');
$formatter = new MessageFormatter('en_US', '$user');
$formatter = new MessageFormatter('hi_HI', '$user');
        $login    = $this->request->getPost('login');
        $password = $this->request->getPost('password');
$formatter = new MessageFormatter('fr_FR', '$ password?);
$formatter = new MessageFormatter('en_US', '$ password ');
$formatter = new MessageFormatter('hi_HI', '$ password ');
if ($user === false) { 
            $this->flash->error("Incorrect credentials"); 
            return $this->dispatcher->forward(array( 
               'controller' => 'users', 'action' => 'index' 
            )); 
         } 
         $this->session->set('auth', $user->id);  
         $this->flash->success("You've been successfully logged in");

        $user->login = $login;

        // Store the password hashed
        $user->password = $this->security->hash($password);

        $user->save();
    }
}

Output:
