laravel如何实现批量插入

1.自己写的做个记录

try {
            $str  = '[{"pageid":"270"},{"que":[{"title":"sad","type":"1","option_a":"sad","option_b":"sad","option_c":"dad","option_d":"ad","option_e":"d","option_f":"da","option_g":"sda","option_h":"d","answer":"sdad"},{"title":"sdaf","type":"1","option_a":"sfa","option_b":"fa","option_c":"da","option_d":"d","option_e":"d","option_f":"dd","option_g":"ad","option_h":"add","answer":"ad"},{"title":"wedwq","type":"1","option_a":"ea","option_b":"aaas","option_c":"ssssdas","option_d":"ad","option_e":"ad","option_f":"adad","option_g":"wdqd","option_h":"ws","answer":"ada"},{"title":"dwq","type":"1","option_a":"ad","option_b":"ad","option_c":"dad","option_d":"dad","option_e":"ad","option_f":"dw","option_g":"ad","option_h":"sad","answer":"d"},{"title":"af","type":"1","option_a":"sad","option_b":"a","option_c":"af","option_d":"saf","option_e":"asfdf","option_f":"da","option_g":"fs","option_h":"dasf","answer":"afa"}]}]';
            $info = json_decode($str);
            $arr = $info[1];
            $value='';
            foreach ($arr as $k=>$value) {
                $value=$value;
            }
            $pageid=$info[0]->pageid;
            foreach ($value as  $info){

                $arr1 = [
                    'title' => $info->title,//题目
                    'type' => $info->type,//题目类型
                    'option_a' => $info->option_a,//A
                    'option_b' => $info->option_b,//B
                    'option_c' => $info->option_c,//C
                    'option_d' => $info->option_d,//D
                    'option_e' => $info->option_e,//E
                    'option_f' => $info->option_f,//F
                    'option_g' => $info->option_g,//G
                    'option_h' => $info->option_h,//H
                    'answer' => $info->answer,//正确答案
                    'pageid'=>$pageid,
                ];
                DB::table('v')->insert($arr1);

            }



        } catch (Exception $exception) {
            $exception->getMessage();
        }

 数据库信息

CREATE TABLE `v` (
  `id` int(4) NOT NULL AUTO_INCREMENT,
  `title` varchar(200) NOT NULL,
  `type` int(1) DEFAULT NULL,
  `option_a` varchar(100) DEFAULT NULL,
  `option_b` varchar(100) DEFAULT NULL,
  `option_c` varchar(100) DEFAULT NULL,
  `option_d` varchar(100) DEFAULT NULL,
  `option_e` varchar(100) DEFAULT NULL,
  `option_f` varchar(100) DEFAULT NULL,
  `option_g` varchar(100) DEFAULT NULL,
  `option_h` varchar(100) DEFAULT NULL,
  `answer` varchar(100) DEFAULT NULL,
  `score` int(11) DEFAULT NULL,
  `pageid` int(11) DEFAULT NULL,
  `token` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `token` (`token`) USING BTREE
) ENGINE=MyISAM AUTO_INCREMENT=105 DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC COMMENT='知识竞赛表';

3.自己写的版本二

 public function store(Request $request)
    {
       $str=$request->except('_token');
        $str=implode($str);//将数组转化为字符串（由于传输过来的是单个数组所以只能转化为字符串进行操作）
        $info = json_decode($str);//转换为json数组
        $arr = $info[1];//得到数组第一小数组个信息
        $value='';//下面循环将第二个数组的首字符去掉然后保存为新的数组
        foreach ($arr as $k=>$value) {
            $value=$value;
        }
        $pageid=$info[0]->pageid;//得到id
        $type_num=PolicePage::find($pageid);
        $type_num=$type_num->page_type;
        switch ($type_num){
            case  0:
                foreach ($value as  $info){
                    $arr1 = [
                        'title' => $info->title,//题目
                        'type' => $info->type,//题目类型
                        'option_a' => $info->option_a,//A
                        'option_b' => $info->option_b,//B
                        'option_c' => $info->option_c,//C
                        'option_d' => $info->option_d,//D
                        'option_e' => $info->option_e,//E

                        'answer' => $info->answer,//正确答案
                        'pageid'=>$pageid,

                    $data=PoliceExam::create($arr1);
                }
                break;
            case  1:
                foreach ($value as  $info){
                    $arr1 = [

                }
                break;
            case  2:

                    $arr1 = [
