laravel如何阅读app / config / app.php调试变量

Question

How do I access the debug variable in app/config/app.php from my controller to see if I am in debug mode?

<?php

Answer 1

You can use the helper function config (Laravel 5+).

$debug = config('app.debug');

Laravel 4.2:

$debug = Config::get('app.debug');

Answer 2

This question already has right answer, I just wanted to add that doing it with environmental variables is a better option:

'debug' => env('APP_DEBUG', false),

In .env file:

APP_ENV=local
