Laravel subdomain specific locale

I needed to change the locale of one of my laravel based projects based on the subdomain. The setup was as follows -

• www.domain.com (en)
• de.domain.com (de)
• es.domain.com (es)

I implemented the following inside AppServiceProvider to get the job done:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        //
    }

    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
        //subdomain specific locale
        $subdomain = current(explode('.', $_SERVER['HTTP_HOST']));

        if (in_array($subdomain, ["www","fr","de"])) {
            if($subdomain !== 'www'){
                app()->setLocale($subdomain);
                config('app.url',$subdomain.'.domain.com');
            } else {
                app()->setLocale('en');
                config('app.url','www.domain.com');
            }            
        } else {
            app()->setLocale('en');
            config('app.url','www.domain.com');
        }
    }
}

Hope this helps someone in future!
