13 * Stub class for backwards compatibility.
15 * Since PHP 7 adds "null" as a reserved keyword, we can no longer have a class
16 * named that and retain PHP 7 compatibility. The original class has been
17 * renamed to "ToNull", and this class is now an extension of it. It raises an
18 * E_USER_DEPRECATED to warn users to migrate.
