比对差异数据有问题

   /**
     * 获取变化的数据 并排除只读数据
     * @access public
     * @return array
     */
    public function getChangedData()
    {
        if ($this->force) {
            $data = $this->data;
        } else {
            $data = array_udiff_assoc($this->data, $this->origin, function ($a, $b) {
                if ((empty($a) || empty($b)) && $a !== $b) {
                    return 1;
                }
                return is_object($a) || $a != $b ? 1 : 0;    //这里有个疑问 $a=1  $b='1-11' 也不能正常比较出差异
            });
        }

        if (!empty($this->readonly)) {
            // 只读字段不允许更新
            foreach ($this->readonly as $key => $field) {
                if (isset($data[$field])) {
                    unset($data[$field]);
                }
            }
        }

        return $data;
    }

Start by locating the getChangedData() entry point shown in the issue and reproduce the comparison using 1 and '1-11'. Trace how the current comparison result identifies changed data, then verify that the reported mismatch is handled correctly.
