Phalcon php multilingual routing - php

Question

Hi I'm new to the php world.
I'm wondering What is the best way to handle multilingual routing ?
I'm starting to create a website with Phalcon php.
I have the following routing structure.
$router->add('/{language:[a-z]{2}}/:controller/:action/:params', array(
'controller' => 2,
'action' => 3,
'params' => 4,
));
$router->add('/{language:[a-z]{2}}/:controller/:action', array(
'controller' => 2,
'action' => 3,
));
$router->add('/{language:[a-z]{2}}/:controller', array(
'controller' => 2,
'action' => 'index',
));
$router->add('/{language:[a-z]{2}}', array(
'controller' => 'index',
'action' => 'index',
));
My problem is for instance when I go on mywebsite.com/ I want to change my url in the dispatcher like mywebsite.com/en/ or other language. Is it a good practise to handle it in the beforeDispatchLoop ? I seek the best solutions.
/**Triggered before entering in the dispatch loop.
* At this point the dispatcher don't know if the controller or the actions to be executed exist.
* The Dispatcher only knows the information passed by the Router.
* #param Event $event
* #param Dispatcher $dispatcher
*/
public function beforeDispatchLoop(Event $event, Dispatcher $dispatcher)
{
//$params = $dispatcher->getParams();
$params = array('language' => 'en');
$dispatcher->setParams($params);
return $dispatcher;
}
This code doesn't work at all, my url is not change. The url stay mywebsite.com/ and not mywebsite.com/en/
Thanks in advance.
I try one solution above.
The redirect doesn't seems to work. I even try to hard-coded it for test.
use Phalcon\Http\Response;
//Obtain the standard eventsManager from the DI
$eventsManager = $di->getShared('eventsManager');
$dispatcher = new Phalcon\Mvc\Dispatcher();
$eventsManager->attach("dispatch:beforeDispatchLoop",function($event, $dispatcher)
{
$dispatcher->getDI->get('response')->redirect('/name/en/index/index/');
}

I think you are confusing something. If I understand correctly: you want to redirect users to a valid url if they open a page without specifying a language.
If that's the case you should verify in your event handler whether the language parameter is specified and redirect user to the same url + the default language if its missing. I am also assuming that your beforeDispatchLoop is located in your controller, which is also part of the problem, because your route without a language never matches and you never get into that controller. Instead you need to use it as an event handler with the event manager as per the documentation. Here is how you do the whole thing.
$di->get('eventsManager')->attach("dispatch:beforeDispatchLoop", function(Event $event, Dispatcher $dispatcher)
{
$params = $dispatcher->getParams();
// Be careful here, if it matches a valid route without a language it may go into a massive
// recursion. Really, you probably want to use `beforeExecuteRoute` event or explicitly
// check if `$_SERVER['REQUEST_URI']` contains the language part before redirecting here.
if (!isset($params['language']) {
$dispatcher->getDI->get('response')->redirect('/en' . $_SERVER['REQUEST_URI']);
return false;
}
return $dispatcher;
});
