Set Application_ENV via virtual host config and read this in PHP
Since SetEnv set's the value to Apache's environment, you can get it with
apache_getenv
— Get an Apache subprocess_env variable
or just
getenv
— Gets the value of an environment variable
If you look at public/index.php
in a ZF project, you will see ZF uses getenv
:
// Define application environmentdefined('APPLICATION_ENV') || define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'production'));
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'); }}
This way, you don't have to rely on the environment setting at all.
SetEnv
defines an environment variable.
Once this has been set (either in your Apache's configuration, or at the system level), you can read its value using the getenv
function :
echo getenv('APPLICATION_ENV');
For instance, if you use this in your .htaccess
file :
SetEnv TEST glop
You can use this portion of PHP code :
var_dump(getenv('TEST'));
And you'll get :
string 'glop' (length=4)
