$data was never initialized. Although not strictly required by PHP, it is generally a good practice to add $data = array(); before regardless.

        $data['region'] = '61';

        if (strlen($phone)>=12) {
            $data['country'] = substr((string) $phone, 0, 2);
            $phone = substr((string) $phone, 2, strlen($phone)-2);
        }

        if (strlen($phone)>=10) {
            $data['region'] = substr((string) $phone, 0, 2);
            $phone = substr((string) $phone, 2, strlen($phone)-2);
        }

        $data['number'] = $phone;
        return $data;
    }

    public static function isSame(string $to, string $from)
