通过虚拟主机配置设置 Application_ENV 并在 PHP 中读取它 [英] Set Application_ENV via virtual host config and read this in PHP
问题描述
我喜欢它在 Zend Framework 中的工作方式.通过检查控制器中的 APPLICATION_ENV 常量,我可以知道我当前使用的是哪个环境.
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,我无法在当前项目中使用 ZF.如何在我的 PHP 代码中检查这个环境变量?
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
自从 SetEnv 设置 Apache 环境的值,你可以用
Since SetEnv set's the value to Apache's environment, you can get it with
apache_getenv
— 获取一个 Apache subprocess_env 变量
或者只是
getenv
— 获取值环境变量
如果您查看 ZF 项目中的 public/index.php
,您会看到 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'));

一个经常使用的替代方法是从 PHP 读取主机名并相应地定义常量:
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.yourdomain.com')) {
define(APPLICATION_ENV, 'development');
} else {
define(APPLICATION_ENV, 'production');
}
}
这样,您完全不必依赖环境设置.
This way, you don't have to rely on the environment setting at all.
