Jetpack Constants
A simple constant manager for Jetpack.
Testing constants is hard. Once you define a constant in PHP, it's defined. Constants Manager is an abstraction layer so that unit tests can set constants for tests.
Usage
Retrieve the value of a constant CONSTANT_NAME (returns null if it's not defined):
use Automattic\Jetpack\Constants;
$constant_value = Constants::get_constant( 'CONSTANT_NAME' );Set the value of a constant CONSTANT_NAME to a particular value:
use Automattic\Jetpack\Constants;
$value = 'some value';
Constants::set_constant( 'CONSTANT_NAME', $value );Check whether a constant CONSTANT_NAME is defined:
use Automattic\Jetpack\Constants;
$defined = Constants::is_defined( 'CONSTANT_NAME' );Check whether a constant CONSTANT_NAME is truthy:
use Automattic\Jetpack\Constants;
$is_truthy = Constants::is_true( 'CONSTANT_NAME' );Delete the CONSTANT_NAME constant:
use Automattic\Jetpack\Constants;
Constants::clear_single_constant( 'CONSTANT_NAME' );Delete all known constants:
use Automattic\Jetpack\Constants;
Constants::clear_constants();
