lang prefix in urls

[thierryler]

Hello,

My website uses urls that can include the language as prefix.

For example:
website.com/en/article/abcd123
website.com/fr/article/abcd123

Or also (especially for google reasons):
website.com/en-us/article/abcd123
website.com/en-uk/article/abcd123

But this prefix is optional. The default lang is set to 'fr' if missing.
For example:
website.com/article/abcd123

Actually, all those example urls should go to the same controller, asking the "article" with id "abcd123". The only difference is the lang.

My question is about the "lang" parameter here. What do you recommend to handle that?

PS : I have many languages on my website (fr, en, it, sp, etc.) and many routes (article, pay, profil, etc.). I do not want to double each route for each lang.

$router->map('GET', '/[*:lang]?/article/[a:id]');

lang parameter is optional here.
