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 [](#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(); ``` Using this package in your WordPress plugin ------------------------------------------- [](#using-this-package-in-your-wordpress-plugin) If you plan on using this package in your WordPress plugin, we would recommend that you use [Jetpack Autoloader](https://packagist.org/packages/automattic/jetpack-autoloader) as your autoloader. This will allow for maximum interoperability with other plugins that use this package as well. Security -------- [](#security) Need to report a security vulnerability?
