I’m using phpfog.com for hosting and github.com for issue tracking, etc. I have two remotes setup, one to phpfog.com, and the other to github.
In the back-end admin of phpfog you can define Environment Variables. I did so there and want to use them in my wp-config file.
Here’s the code I used:
/** Hardened Salts for use on github.com, phpfog.com, etc.*/ $AUTH_KEY = getenv('AUTH_KEY'); $SECURE_AUTH_KEY = getenv('SECURE_AUTH_KEY'); $LOGGED_IN_KEY = getenv('LOGGED_IN_KEY'); $NONCE_KEY = getenv('NONCE_KEY'); $AUTH_SALT = getenv('AUTH_SALT'); $SECURE_AUTH_SALT = getenv('SECURE_AUTH_SALT'); $LOGGED_IN_SALT = getenv('LOGGED_IN_SALT'); $NONCE_SALT = getenv('NONCE_SALT'); define('AUTH_KEY',$AUTH_KEY); define('SECURE_AUTH_KEY',$SECURE_AUTH_KEY); define('LOGGED_IN_KEY',$LOGGED_IN_KEY); define('NONCE_KEY',$NONCE_KEY); define('AUTH_SALT',$AUTH_SALT); define('SECURE_AUTH_SALT',$SECURE_AUTH_SALT); define('LOGGED_IN_SALT',$LOGGED_IN_SALT); define('NONCE_SALT',$NONCE_SALT); /** ------------------------------------=-----*/
There must be a cleaner way of doing this…
UPDATE! Here’s the cleaned up code thanks to zerkms
$dbvalues = array('DB_HOST', 'DB_NAME', 'DB_USER', 'DB_PASSWORD'); /** -------------------------------------------------------------*/ foreach ($dbvalues as $dbvalue) { define($dbvalue, getenv($dbvalue)); } $saltykeys = array('AUTH_KEY', 'SECURE_AUTH_KEY', 'LOGGED_IN_KEY', 'NONCE_KEY', 'AUTH_SALT', 'SECURE_AUTH_SALT' , 'LOGGED_IN_SALT', 'NONCE_SALT' ); /** -------------------------------------------------------------*/ foreach ($saltykeys as $saltykey) { define($saltykey, getenv($saltykey)); }

You could make it twice shorter passing the function result as a constant value without intermediate variable:
define('AUTH_KEY', getenv('AUTH_KEY'));
Or do that in a loop:
$vars = array('AUTH_KEY', 'SECURE_AUTH_KEY', ...); foreach ($vars as $var) { define($var, getenv($var)); }
