Get environment value in controller

Step 1.) Add your variable to your .env file, ie.

EXAMPLE_URL="http://google.com"

Step 2.) Create a new file inside of the config folder, any name, ie.

config/example.php

Step 3.) Inside of this new file, I add an array being returned, containing that env variable.

<?php
return [
  'url' => env('EXAMPLE_URL')
];

Step 4.) Because I named it "example" my configuration 'namespace' is now an example. So now, in my controller I can access this variable with:

$url = \config('example.url');

Example

public static function mail($param)
{
    //$_ENV['yourkeyhere'];
    $mailgunsecret = env('MAILGUN_SECRET');
    $mailguurl = env('MAILGUN_DOMAIN');

}

$data = array(

            "MAIL_DRIVER" => env('MAIL_DRIVER'),

            "MAIL_HOST" => env('MAIL_HOST'),

            "MAIL_PORT" => env('MAIL_PORT'),

            "MAIL_USERNAME" => env('MAIL_USERNAME'),

            "MAIL_PASSWORD" => env('MAIL_PASSWORD'),

            "MAIL_ENCRYPTION" => env('MAIL_ENCRYPTION')

        );

        $response = json_encode($data);
return response()->json(['status' => "ok",'data' => $response    ], 200);
