Translation based on hostname

Do you have a list of all domains and subdomains your app will be using? If answer is positive, then sure, there are ways to handle it. Otherwise using REGEXP is the only way.

First, which adapter do you use to read translation messages? Phalcon\Translate\Adapter\NativeArray ?

Right now, I have this code. And I use NativeArray. But later, i will can use another adapter (Gettext).

$di->setShared('router', function () use ($di, $config) {
    $router = new \Phalcon\Mvc\Router(false);
    $router->setDI($di);
    $router->setDefaultNamespace('controllers');
    $router->removeExtraSlashes(true);

    foreach ($config->sites as $hostname => $route) {
        $hostname_pattern =  '^(([a-z]{2}|www)\.)?' . str_replace('.', '\.', $hostname);
        $router->addGet('/', $route)->setHostname($hostname_pattern);
    }
    $router->notFound(['controller' => 'error', 'action' => 'route']);
    $router->handle();
    return $router;
});

hmm i would do this the other way araound i tihink. I will use apache/nging to take care of this for me.

And base on this https://stackoverflow.com/questions/146354/setting-php-variables-in-httpd-conf

vhost 1:

root : /var/www/site/
SetEnv _lang  english

vhost 2: 

root: /var/www/site
SetEnv _lang french

so after that i can create my php function

function getLang(){
    // if isset($_SERVER["_lang"]; ...
    else 
    check the subdomain etc...
}

Good idea @Izopi4a
