Laravel 5.2 dynamic environment variables based on user

In my .env file I have two variables

App_id: 12345
App_secret: abc123

But I'm wondering if there's a way so that if user userNo2 logs in then it would instead use

App_id: 45678
App_secret: abc456

Is there a way to have if/else functionality in the env file based on the user?

Yes it is possible, but not in the .env file. Instead, you can move your logic to middleware:

Step 1: Add default values to the application config

Open your app/config/app.php and add your default values to the existing array.

<?php

return [
    'APP_ID' => '45678',
    'APP_SECRET' => 'abc456',
    ...
];

Step 2: Create a new Middleware

php artisan make:middleware SetAppConfigForUserMiddleware

Edit the file to look like this:

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Config;

class SetAppConfigForUserMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
         $authorizedUser = Auth::user();

        if (!App::runningInConsole() && !is_null($authorizedUser)) {
            Config::set('app.APP_ID', 'appidOfUser' . $authorizedUser->name);
            Config::set('app.APP_SECRET', 'appsecretOfUser' . $authorizedUser->email);
        }
        return $next($request);
    }
}

Step 4: Run your middleware

If you need to set this config for the user in all the web routes you can add to the $middlewareGroups array in app/Http/kernel.php. This will apply the middleware to all the routes inside web.php.

/**
 * The application's route middleware groups.
 *
 * @var array
 */
protected $middlewareGroups = [
    'web' => [
        ...
        \App\Http\Middleware\SetAppConfigForUserMiddleware::class,        
    ],

Step 5: Testing

For example, my Auth:user()->name is "John" and my Auth:user()->email is "john@example.com"

If you put this in your resources/views/home.blade.php

App Id Of User <code>{{config('app.APP_ID')}}</code>
App Secret Of User <code>{{config('app.APP_SECRET')}}</code>

The result will be appidOfUserJohn and appsecretOfUserjohn@example.com.
