Setup
All classes are in the duncan3dc\Env namespace.
require_once __DIR__ . "vendor/autoload.php";
use duncan3dc\Env\Env;
Paths
If you want to use the path based features of the project then you should define the root path.
By default the Env class assumes your project root is the parent of the composer vendor directory, however you might want to override it:
# Use the webservers document path (found in $_SERVER["DOCUMENT_ROOT"])
Env::usePath(Env::PATH_DOCUMENT_ROOT);
# Use the initial PHP script this request originated from ($_SERVER["PHP_SELF"])
Env::usePath(Env::PATH_PHP_SELF);
# Use a specific hard-coded path
Env::usePath(__DIR__);
Environment Variables
You can load environment variables from the global $_ENV array:
Env::setEnvironment(new \duncan3dc\Env\GlobalEnvironment);
Or from a local YAML encoded file:
$path = Env::path("data/env.yaml");
Env::setEnvironment(new YamlEnvironment($path));
Or from a local JSON encoded file:
$path = Env::path("data/env.json");
Env::setEnvironment(new JsonEnvironment($path));
Or from any source you like
