Hi,
- Yes.
- The second argument is only use if you don't set the environment variable.
- You need to set this environment variable on your
.envfile.

Understanding Env. Variables
I Have watched Jeffrey's lesson on this as well as read the L5 docs and read Matt Stauffers guide on upgrading and still. I have a general idea how .env works but the specifics are not clear to me:
-
In my .env file I set up 1 and only 1 environment eg "local" or "production" - correct?
-
In config/database.php I the second value in the below array is "forge" - but I am not using forge, so what kind of fall back would I put in there ?
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
- In matt stauffers guide to upgrading, he says:
Now, you can edit your APP_ENV--which, as you can tell from the default, is the primary way for us to set the application environment name. Check out the newer, simpler environment detection in bootstrap/environment.php:
Where do I find " APP_ENV" ? Also, there is no file bootstrap/environment.php.
Then he goes on to reference:
$env = $app->detectEnvironment(function()
{
return getenv('APP_ENV') ?: 'production';
});
Sorry if these are dumb questions, but I have tried to find the answers for myself, without much luck.
Many thanks !!

It's all in the example https://github.com/laravel/laravel/blob/master/.env.example
Don't need a default but you can put something that will allow it not to error. At least don't put local as the default :P

Ok - I'm starting to get it, but i still don't get the Matt Stauffer thing. What does this code actually do ? why am I using it ?
What does Matt mean by bootstrap/environment.php ?
Am I supposed to this:
APP_ENV=local
APP_DEBUG=true
APP_KEY=Z1GsXPpJxJYR1sL5IKvBFnIbiH6dG7qY
DB_HOST=localhost
DB_DATABASE= mydb
DB_USERNAME=myusername
DB_PASSWORD=mypassword
CACHE_DRIVER=file
SESSION_DRIVER=file
$env = $app->detectEnvironment(function()
{
return getenv('APP_ENV') ?: 'local';
});

ENV vars are just http://php.net/manual/en/reserved.variables.environment.php
I think that file was removed from L5 and since Matt wrote it WAY before it was released, I can assume that is why. (Posted on October 16, 2014 | By Matt Stauffer)

Ok - I kinda got what ENV vars are, but that Matt thing really through me. So, summing up, I ignore the Matt piece and I just put my env variables into .env and be happy !
You are a mega star thank you !

There are ways to change environment depending on something but bootstrap/environment.php isn't the way. I've seen a few threads on here about it but I don't think you need anything advanced? Just want to set it to local right?
Level 15
yup - local for now, and then later, production when it is uploaded.

Depending on where you upload, you won't even have the .env file in production. It is merely a work around to keep you having to constantly bounce nginx/apache when you are adding new environment variables whilst developing.
If you're using Forge, you'll set the environment variables via the Forge interface and not have a .env file at all - just set the keys and values there.
The environment detection is now done within Illuminate/Foundation/Bootstrap/DetectEnvironment.php and basically loads your environment variables, then uses the APP_ENV value if it's set, defaulting to production.
