Laravel: Where to store global arrays data and con

Question

I just started working with Laravel. I need to rewrite a whole system I made some years ago, using Laravel 4 as base framework. In my old system I use to have a constant.php file with some constants declared, and a globals.php file which contained lots of array sets (For example, categories statuses, type of events, langs, etc.). By doing so, I could use something like

foreach ( $langs as $code => $domain ) {
    // Some stuff
}

anywhere in my app.

My question is, how can I store that info in the so called "laravel way". I tried using some sort of object to store this info, setting this as a service and creating for it a facade:

app/libraries/Project/Constants.php

namespace PJ;

class Constants {

    public static $langs = [
            'es' => 'www.domain.es',
            'en' => 'www.domain.us',
            'uk' => 'www.domain.uk',
            'br' => 'www.domain.br',
            'it' => 'www.domain.it',
            'de' => 'www.domain.de',
            'fr' => 'www.domain.fr'
        ];

}

app/libraries/Project/ConstantsServiceProvider.php

namespace PJ;

use Illuminate\Support\ServiceProvider;

class ConstantsServiceProvider extends ServiceProvider {
    public function register() {
        $this->app->singleton('PJConstants', function() {
            return new Constants;
        });
    }
}

app/libraries/Project/ConstantsFacade.php

namespace PJ;

use Illuminate\Support\Facades\Facade;

class ConstantsFacade extends Facade {
    protected static function getFacadeAccessor() { 
        return 'PJConstants';
    }
}

composer.json

"psr-4": {
     "PJ\\": "app/libraries/Project"
},

and so I access that property as PJ\Constants::$langs.

This works, but I doubt it is the most efficient / Correct way to do it. I mean, is it the right way to "propagate" a variable by creating a while Service Provider and facades and all such stuff? Or where should I put this data?

Thanks for any advice.

EDIT # 01

Data I want to pass to all controllers and views can be directly set in script, like in the example at the beginning of my post, but it can also be generated dinamically, from a database for example. This data could be a list of categories. I need them in all views to generate a navigation bar, but I also need them to define some routing patterns (like /category/subcategory/product), and also to parse some info in several controllers (Like get info from the category that holds X product).

My array is something like:

$categories = [
    1 => ['name' => 'General', 'parent' => 0, 'description' => 'Lorem ipsum...'],
    2 => ['name' => 'Nature', 'parent' => 0, 'description' => 'Lorem ipsum...'],
    3 => ['name' => 'World', 'parent' => 0, 'description' => 'Lorem ipsum...'],
    4 => ['name' => 'Animals', 'parent' => 2, 'description' => 'Lorem ipsum...']
]

Just as an example. Index is the id of the category, and the Value is info associated with the category.

I need this array, also, available in all Controllers and Views.

So, if I save it as a Config variable, is it ok? Or how else could I store these data? What would be a best and semantically correct way?

Thanks

Just to add to the above answer you will have to include the config class before you could start using it in Laravel 5.3

use Illuminate\Support\Facades\Config;
