Laravel 5.4 environment based config files - php

Question

I am trying to change the Laravel configuration variables based on environment, but I do not know how.
Code to get config is
Config::get( 'contants.api_url' );
I am trying to have a separate results for the live environment and the development environment.
Real life scenario
I need to override some config files, so everybody who is using the development environment, has the same base configuration. I cannot use the .env file for this, because it is not shared between the team and everybody has their own version of it.
What did I try:
I read here Laravel 5 configuration - environments and overriding that you can create subfolders within your /config folder, that match the environment, to override the default config files. Alas it did not work for me and the Laravel 5.4 documentation on the subject matter (https://laravel.com/docs/5.4/configuration#retrieving-environment-configuration) did not speak about this option, thus I believe it might have been deprecated.

Answer 1

One option could be to use a service provider. If you're only going to be overriding one or two values then you might as well just use your AppServiceProvider, otherwise I would suggest creating a new service (e.g. ConfigServiceProvider).
In the boot() method of your service provider you could add something like:
if (app()->environment() === 'local') {
config()->set('contants.api_url', 'http://example.com');
}

To change the configuration variables based on environment, this will do:
Example file: config/database.php
'mysql' => [
'driver' => mysql,
'url' => env('DATABASE_URL'),
'host'=> (env('APP_ENV') === 'local' ? env('DB_HOST_LOCAL') : env('DB_HOST_PRODUCTION')),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'default'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
'options' => (env('APP_ENV') === 'local' ? [
'some_option' => env('SOME_ENV')
] : []),
],
Tested and works on Laravel 5.8.
