通过虚拟主机配置设置Application_ENV和PHP阅读 [英] Set Application_ENV via virtual host config and read this in PHP

问题描述

我想这是如何工作的Zend框架。我知道我目前在我的控制器检查APPLICATION_ENV不断使用的环境。

I like how this works in Zend Framework. I can know which environment I'm currently using by checking APPLICATION_ENV constant in my controller.

<VirtualHost *:80>
    #ServerName 
    #DocumentRoot

        SetEnv APPLICATION_ENV "development"

    # Directory
</VirtualHost>

但不幸的是，我不能在我目前的项目中使用ZF。我怎么能在我的PHP code检查这个环境变量？

But unfortunately I can't use ZF in my current project. How can I check this environment variable in my PHP code?

推荐答案

SETENV 设置的值到Apache的环境中，你可以得到它。

Since SetEnv set's the value to Apache's environment, you can get it with

• apache_getenv - 找一个Apache subprocess_env变量

或只是

• GETENV - 获取环境变量的值

如果你看看一个ZF项目公共/ index.php文件，你会看到ZF使用 GETENV ：

If you look at public/index.php in a ZF project, you will see ZF uses getenv:

// Define application environment
defined('APPLICATION_ENV')
    || define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? 
                                  getenv('APPLICATION_ENV') : 
                                  'production'));

这是经常使用的另一种方法是看从PHP的主机名和定义常量相应：

---

An often use alternative would be to read the Hostname from PHP and define the constant accordingly:

if(!defined('APPLICATION_ENV')) {
    if(FALSE === stripos($_SERVER['SERVER_NAME']), 'www.example.com') {
        define(APPLICATION_ENV, 'development');
    } else {
        define(APPLICATION_ENV, 'production');
    }
}

这样，您就不必依赖于环境设置的。

This way, you don't have to rely on the environment setting at all.
