我可以在异常处理程序中访问环境变量吗

Question

我需要在.env的{​​{1}}文件中获取常量，

我更改了 Handle.php

Exception/Handler.php

和 env（'APP_DEBUG'）返回null ，有什么想法吗？

Answer 1

The reason about env function return 'null'

Answer 2

    As you know you have debug variable in env something like the below:
    'debug' => env('APP_DEBUG', false);
    Laravel 5+:
    then you can access it like $debug = config('app.debug');
    Laravel 4.2:
    $debug = Config::get('app.debug');
    but before going further just check you get the value for it, if you have set value of APP_DEBUG as false in env then you will get 0 but you can't see it while printing so create a condition such as
    if (config('app.debug')) {
      echo "Yes";
    } else {
      echo "No";
    }

once you get the output you are ready to go further.
