PHP dotenv for codeigniter

Loads environment variables from .env to getenv() automagically.

This is a PHP version of the original Ruby dotenv.

Why .env?

You should never store sensitive credentials in your code. Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments – such as database credentials or credentials for 3rd party services – should be extracted from the code into environment variables.

Basically, a .env file is an easy way to load custom configuration variables that your application needs without having to modify .htaccess files or Apache/nginx virtual hosts. This means you won't have to edit any files outside the project, and all the environment variables are always set no matter how you run your project - Apache, Nginx, CLI, and even PHP 5.4's built-in webserver. It's WAY easier than all the other ways you know of to set environment variables, and you're going to love it.

• NO editing virtual hosts in Apache or Nginx
• NO adding php_value flags to .htaccess files
• EASY portability and sharing of required ENV values
• COMPATIBLE with PHP's built-in web server and CLI runner

Manual Installation without Composer

• copy folder "system" to your codeigniter projects

• add this code to your codeigniter index.php before codeigniter core loaded (before this text "* LOAD THE BOOTSTRAP FILE")

/*
 * --------------------------------------------------------------------
 * LOAD PHP DOT ENV FILE
 * --------------------------------------------------------------------
 *
 * And away we go...
 *
 */
require_once BASEPATH . 'dotenv/autoloader.php';

$dotenv = new Dotenv\Dotenv(__DIR__);
$dotenv->load();

• in file "application/config/database.php" change to this configuration

$db['default']['hostname'] = getenv('DB_HOST');
$db['default']['username'] = getenv('DB_USERNAME');
$db['default']['password'] = getenv('DB_PASSWORD');
$db['default']['database'] = getenv('DB_DATABASE');
$db['default']['dbdriver'] = getenv('DB_CONNECTION');

• create ".env" by copy file ".env.example" for database configuration and the other configuration

• add ".env" to your .gitignore file

• and it will be running, thank you
