Environment PHP Library by John Smart (@thesmart)
Easily manage database connection strings or other configuration data that changes across server environments such a dev and prod.
This runs one time at the start of your void main:
// construct an instance
new Env('dev');
// development http server url
Env::set('url', array(
'scheme' => isset($_SERVER) && isset($_SERVER['HTTPS']) ? 'https' : 'http',
'domain' => 'dev-github.com'
));
// development memcached server connection strings
Env::set('memached.main', array(
'port' => 11211,
'addr' => '127.0.0.1'
));
// alternative syntax
Env::set('facebook.appId', '012345678');
Env::set('facebook.secret', '000000000000000000000000000000'); // keep secret
Env::set('facebook.namespace', 'app_name_space');
Env::set('facebook.url', 'https://apps.facebook.com/app_name_space');
Later, you can easily access current environment variables:
// access using dot-notation
$facebookConfig = Env::get('facebook');
$memcached = new \Memcached();
$memcached->addServer(Env::get('memcached.main.addr'), Env::get('memcached.main.port'));
if (Env::has('memcached')) {
// go cache some shit
}
Mix with OS environment variables to define which configuration to use:
$configToSet = isset($_SERVER['conf']) ? $_SERVER['conf'] : 'prod';
require_once PATH_CONFIG . $configToSet . '.php';
