Laravel 4 Database configuration with $_ENV - php

Question

I want to use Laravel Environment for my Database credential, I did this:
inside bootstrap\start.php :
$env = $app->detectEnvironment(array(
'local' => array('My_PC'),
'production' => array('server.example.com')
));
created .env.local.php on same directory where serve.php is, and inside this code:
return array(
'DATABASE_NAME' => 'laravel_db',
'DATABASE_USER' => 'root',
'DATABASE_PASSWORD' => '1234'
);
and inside app\config created a local\app.php file containing this code:
return array(
'debug' => true,
);
and inside the app\config\database.php for my secured mysql connection I did:
'mysql' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => $_ENV['DATABASE_NAME'],
'username' => $_ENV['DATABASE_USER'],
'password' => $_ENV['DATABASE_PASSWORD'],
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
but I'm getting an error on the CLI:
{"error":{"type":"ErrorException","message":"Undefined index: DATABASE_NAME","file":"c:\\xampp\\htdocs\\Larave_project\\app\\config\\database.php","line":58}}
How to resolve this issue?

Answer 1

The hostname based env detection solution will only work on Unix type system.
It won't work on Windows.

In Laravel 4.2 you can detect environment this way:
$env = $app->detectEnvironment(function() {
if ($_SERVER['SERVER_NAME'] == "127.0.0.1") {
$domain = $_SERVER['HTTP_HOST'];
if (strpos($domain, 'localhost') !== FALSE || strpos($domain, "127.0.0.1") !== FALSE) {
die("Configure your local `hosts` file and go to address: http://{storeName}.local");
}
$len = strpos($domain, ".local");
if ($len !== FALSE) {
// will load .env.*.php
$len = strpos($domain, ".local");
$env = substr($domain, 0, $len);
return $env;
}
}
// will load .env.php
return 'production';
});
(this is bootstrap/start.php)
Then:
setup hosts file (in your operating system) to redirect mysuperstore.local to 127.0.0.1
go to URL like http://mysuperstore.local which loads .env.mysuperstore.php into $_ENV.
In configuration files (those placed in app/config/) refer to $_ENV. To see where $_ENV does come from take a look into documentation topic about "Protecting Sensitive Configuration".
