"environment driven database settings in laravel?" Answer’s

You can definitely set database settings (and any other config setting) by environment.

For Laravel 3 (for Laravel 4 and Laravel 5 see below):

Firstly - you need to define $environments in your paths.php and set it to something like this:

$environments = array(
  'development' => array('*.dev'),
  'production' => array('*.com'),
);

Laravel will automatically look for this variable, and if set, will use the associated configuration.

Normally you have a config folder, with settings such as database.php and auth.php

Now just create a new folder for each Laravel_Env you plan to use (such as Development). You'll end up with a folder structure like this;

/application
  /config
    /development
      database.php
    /production
      database.php
    application.php
    config.php
    database.php
    ...
    user_agents.php

You'll note I've only included database.php in each subfolder. Laravel will always load the default config settings first, then override them with any custom configs from the environments setting.

Finally, in your development/database file, you would have something like this;

<?php
 return array(
'default' => 'mysql'
 );

p.s. I just tested this on the current 3.2.12 build of Laravel - and it definitely works.

Bonus Tip: You can also automatically set an environment for Artisan, so you do not have to include the environment manually on each command line! To do this:

  1. You need to know your 'hostname' that you are running Artisan on. To find out - temporarily edit the artisan.php in your root folder, and add var_dump(gethostname()); to line 2 (i.e. above everything).

  2. Run php artisan from the command line. You will get a string dump with your hostname. In my case its "TSE-Win7";

  3. Remove the changes to the artisan.php file

  4. Add your hostname (i.e. "TSE-Win7") to the environments.

You should end up with something like this:

$environments = array(
  'development' => array('*.dev', 'TSE-Win7'),
  'production' => array('*.com'),
);

Artisan will now run using your development environment. If you deploy to a live server - re-run these steps to get the hostname() for the server, and you can configure a specific artisan config just for the server!

For Laravel 4:

The default environment is always production. But in your start.php file you can define additional environments.

 $env = $app->detectEnvironment(array(
   'local' => array('your-machine-name'),
));

On Linux and Mac, you may determine your hostname by type hostname in your terminal - it will output the name of your computer. On Windows put dd(gethostname()); at the beginning of your routes.php file - and run the website once - it will show you the current hostname of your computer.

To get the current environment as a variable in your application - read this SO answer here. Laravel 4: how can I get the environment value?

For Laravel 5:

There is single configuration file, called .env in your root directory. Watch this laracast, config explained fully.
