What is the best practice for adding constants in laravel? (Long List)

For most constants used globally across the application, storing them in config files is sufficient. It is also pretty simple

Create a new file in the config directory. Let's call it constants.php

In there you have to return an array of config values.

return [    'options' => [        'option_attachment' => '13',        'option_email' => '14',        'option_monetery' => '15',        'option_ratings' => '16',        'option_textarea' => '17',    ]];

And you can access them as follows

Config::get('constants.options');// or if you want a specific oneConfig::get('constants.options.option_attachment');

I use aliased class constants :

First, create your class that contain your constants : App/MyApp.php for exemple

namespace App;class MyApp {   const MYCONST = 'val';}

Then add it to the aliased classes in the config/app.php

'aliases' => [  //...  'MyApp' => App\MyApp::class,

Finally use them wherever you like (controllers or even blades) :

MyApp::MYCONST

Your question was about the 'best practices' and you asked about the '.env method'.

.env is only for variables that change because the environment changes. Examples of different environments: test, acceptance, production.

So the .env contains database credentials, API keys, etc.

The .env should (imho) never contain constants which are the same over all environments. Just use the suggested config files for that.
