# 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):
|
|
|
|
```php
|
|
use Automattic\Jetpack\Constants;
|
|
|
|
$constant_value = Constants::get_constant( 'CONSTANT_NAME' );
|
|
```
|
|
|
|
Set the value of a constant `CONSTANT_NAME` to a particular value:
|
|
|
|
```php
|
|
use Automattic\Jetpack\Constants;
|
|
|
|
$value = 'some value';
|
|
Constants::set_constant( 'CONSTANT_NAME', $value );
|
|
```
|
|
|
|
Check whether a constant `CONSTANT_NAME` is defined:
|
|
|
|
```php
|
|
use Automattic\Jetpack\Constants;
|
|
|
|
$defined = Constants::is_defined( 'CONSTANT_NAME' );
|
|
```
|
|
|
|
Check whether a constant `CONSTANT_NAME` is truthy:
|
|
|
|
```php
|
|
use Automattic\Jetpack\Constants;
|
|
|
|
$is_truthy = Constants::is_true( 'CONSTANT_NAME' );
|
|
```
|
|
|
|
Delete the `CONSTANT_NAME` constant:
|
|
|
|
```php
|
|
use Automattic\Jetpack\Constants;
|
|
|
|
Constants::clear_single_constant( 'CONSTANT_NAME' );
|
|
```
|
|
|
|
Delete all known constants:
|
|
|
|
```php
|
|
use Automattic\Jetpack\Constants;
|
|
|
|
Constants::clear_constants();
|
|
```
