note 124256 added to function.json-encode

Be aware that when an error occurs, the return value might be NULL unexpectedly. Example: When running this on PHP < 7.3, you do not get back a string: json_encode('ok', JSON_THROW_ON_ERROR, 512); The constant not being available produces a warning and results in NULL being returned (see https://3v4l.org/ku5AH) – I'd expect false, since that's a failure, or "ok" as the encoded result.
