laravel 4 - detectEnvironment dosen't work

问题

I am trying to set up 2 environment to my laravel 4 project and i just can't id the project environment.

I see in the source code that detectEnvironment in the start.php uses is:

    $args = isset($_SERVER['argv']) ? $_SERVER['argv'] : null;

but when i dd (print) the $_SERVER['argv'] its empty (return null on live server and on my local machine).

do i need to set it up someone?

keep in mind my live server is shared host and i have limited access to config.
i did open dir in /config/ with database.php and set up everything in start.php:

$env = $app->detectEnvironment(array(

    'local' => array('*local*'),

    'live' => array('*live*')

));

This is how I do set my environment:

Create a .environment file in the root of your application and define your environment and add your sensitive information to it:

<?php

return array(

     'APPLICATION_ENV' => 'development', /// this is where you will set your environment

     'DB_HOST' => 'localhost',
     'DB_DATABASE_NAME' => 'laraveldatabase',
     'DB_DATABASE_USER' => 'laraveluser',
     'DB_DATABASE_PASSWORD' => '!Bassw0rT',

);

Add it to your .gitignore file, so you don't risk having your passwords sent to Github or any other of your servers.

Right before $app->detectEnvironment, in the file bootstrap/start.php, load your .environment file to PHP environment:

foreach(require __DIR__.'/../.environment' as $key => $value) 
{
    putenv(sprintf('%s=%s', $key, $value));
}

And then you just have to use it:

$env = $app->detectEnvironment(function () {

    return getenv('APPLICATION_ENV'); // your environment name is in that file!

});

And it will work everywhere, so you don't need to have separate dirs for development and production anymore:

<?php

return array(

    'connections' => array(

         'postgresql' => array(
              'driver'   => 'pgsql',
              'host'     => getenv('DB_HOST'),
              'database' => getenv('DB_DATABASE_NAME'),
              'username' => getenv('DB_DATABASE_USER'),
              'password' => getenv('DB_DATABASE_PASSWORD'),
              'charset'  => 'utf8',
              'prefix'   => '',
              'schema'   => 'public',
         ),

    ),

);

Note that I don't set a fallback:

return getenv('APPLICATION_ENV') ?: 'local';

Because, if I don't set the file, I want it to fail on every server I deploy my app to.

Laravel leverages something similar, you create .env files in the root of your application:

.env.local.php    // this file will appear only in your local environment, not in production
.env.staging.php  // for staging
.env.php          // for production

In those files you add your sensitive information

<?php

return array(

    'DB_HOST' => 'localhost',
    'DB_USER' => 'root',
    'DB_PASS' => '1023809182root@pass',

);

Create your files separated by environment:

app/config/local/database.php app/config/staging/database.php app/config/database.php

An then in your files, or anywhere in your application, you can access your sensitive data via $_ENV or getenv():

$_ENV['DB_HOST']
$_ENV['DB_USER']
$_ENV['DB_PASS']

Example:

'postgresql' => [
    'driver'   => 'pgsql',
    'host'     => 'localhost',
    'database' => getenv('DB_HOST'),
    'username' => getenv('DB_USER'),
    'password' => getenv('DB_PASS'),
    'charset'  => 'utf8',
    'prefix'   => '',
    'schema'   => 'public',
],

But you still have to set the environment name, which might be a problem in your case.

Don't forget to add those files to your .gitignore file, so you don't risk sending them to your github.

Actually $args = isset($_SERVER['argv']) ? $_SERVER['argv'] : null; will work only if arguments passed to the script when running from the command line. So, in Laravel, if you run any artisan command then all the arguments passed to that command will be available in the $_SERVER['argv'] otherwise it'll be always NULL.

To check the environment you may use App::environment() method or App::isLocal() method to check if local and to set different environments you may use:

$env = $app->detectEnvironment(array(
    // replace with your machine/host name, gethostname() will return hostname
    'local' => array('your-machine-name')
));

Or you may use something like this:

$env = $app->detectEnvironment(function(){
    // SheikhHeera-PC is my machine name
    return $_SERVER['HTTP_HOST'] == 'SheikhHeera-PC' ? 'local':'production';
});
