You can not access the environment variable like this.

Inside the .env file you write

IMAP_HOSTNAME_TEST=imap.gmail.com  // I am okay with this

Next, inside the config folder there is a file, mail.php. You may use this file to code. As you are working with mail functionality. You might use another file as well.

return [

//..... other declarations
'imap_hostname_test' => env('IMAP_HOSTNAME_TEST'),
// You are hiding the value inside the configuration as well

];

You can call the variable from a controller using 'config(. Whatever file you are using inside config folder. You need to use that file name (without extension) + '.' + 'variable name' + ')'. In the current case you can call the variable as follows.

$hostname = config('mail.imap_hostname_test');

Since you declare the variable inside mail.php and the variable name is imap_hostname_test, you need to call it like this. If you declare this variable inside app.php then you should call

$hostname = config('app.imap_hostname_test');

It s a better idea to put your configuration variables in a configuration  file   In your case  I would suggest putting your variables in config mail php like    imap hostname    gt  env  IMAP HOSTNAME TEST    imap gmail com     And refer to them by  config  mail imap hostname     It first tries to get the configuration variable value in the  env file and if it couldn t find the variable value in the  env file  it will get the variable value from file config mail php

As  Rajib pointed out  You can t access your env variables using config  myVariable    You have to add the variable to  env file first  Add the variable to some config file in config directory  I usually add to config app php Once done  will access them like Config  get  fileWhichContainsVariable Variable    using the Config Facade  Probably You will have to clear config cache using php artisan config clear AND you will also have to restart server

To simplify  Only configuration files can access environment variables - and then pass them on  Step 1   Add your variable to your  env file  for example  EXAMPLE URL  quot http   google com quot   Step 2   Create a new file inside of the config folder  with any name  for example  config example php  Step 3   Inside of this new file  I add an array being returned  containing that environment variable   lt  php return      url    gt  env  EXAMPLE URL       Step 4   Because I named it  quot example quot   my configuration  namespace  is now example  So now  in my controller I can access this variable with   url    config  example url     Tip - if you add use Config  at the top of your controller  you don t need the backslash  which designates the root namespace   For example  namespace App Http Controllers  use Config     Added this line  class ExampleController extends Controller       public function url             return config  example url             Finally  commit the changes  php artisan config cache  --- IMPORTANT --- Remember to enter php artisan config cache into the console once you have created your example php file  Configuration files and variables are cached  so if you make changes you need to flush that cache - the same applies to the  env file being changed   added to

It Doesn t work in Laravel 5 3  if you want to try to access the value from the controller like below  It always returns null  lt  php       value   env  MY VALUE    default value     SOLUTION  Rather  you need to create a file in the configuration folder  say values php and then write the code like below File values php  lt  php      return             myvalue    gt  env  MY VALUE  null               Add other values as you wish  Then access the value in your controller with the following code  lt  php       value    Config  get  values myvalue    Where  quot values quot  is the filename followed by the key  quot myvalue quot
