如何访问CodeIgniter中设置的环境？

I am new to CodeIgniter. I have found that, in order to manage multiple environments, CodeIgniter uses the following function in index.php

我是CodeIgniter的新手。我发现，为了管理多个环境，CodeIgniter在index.php中使用以下函数

define('ENVIRONMENT', 'development');

to define the environment.

定义环境。

My question is, how can I get which environment set at index.php inside my controllers?

我的问题是，我怎样才能在我的控制器中获得index.php中设置的环境？

2 个解决方案

#1

ENVIRONMENT is defined in index.php that is pipeline of each CI application file, you can access anywhere e.g model, view, controller, library

ENVIRONMENT在index.php中定义，它是每个CI应用程序文件的管道，您可以访问任何地方，例如模型，视图，控制器，库

echo ENVIRONMENT;

#2

In your index.php file, try something like this:

在index.php文件中，尝试以下方法：

if ($_SERVER['HTTP_HOST'] == 'dev' || $_SERVER['HTTP_HOST'] == 'localhost')
{
    define('ENVIRONMENT', 'development');
}
elseif ($_SERVER['HTTP_HOST'] == 'staging.example.com')
{
    define('ENVIRONMENT', 'staging');
}
else
{
    define('ENVIRONMENT', 'production');
}

Obviously, set it up with values that make sense for you. However, this will set the ENVIRONMENT based on where the application is running, automatically.

显然，使用对您有意义的值进行设置。但是，这将根据应用程序的运行位置自动设置环境。
