PHP TP 获取二维数组根据条件取出想要的值

 public function ArrList(){
        
        //$arr是随机，现在我定义的是不随机的，后面取出数据库的也可以用
        $arr = [
            [
                "id" => 1,
                "view" => 2,
                'category_id' => 2,
                'title' => "标题一",
                "model" => 12,
                'desc' => "摘要",
            ],
            [
                "id" => 123,
                "view" => 2,
                'category_id' => 1,
                'title' => "标题二",
                "model" => 101,
                'desc' => "摘要",
            ],
            [
                "id" => 3,
                "view" => 3,
                'category_id' => 3,
                'title' => "标题三",
                "model" => 101,
                'desc' => "摘要",
            ],
            [
                "id" => 4,
                "view" => 12,
                'category_id' => 2,
                'title' => "标题四",
                "model" => 3,
                'desc' => "摘要",
            ],
            [
                "id" => 5,
                "view" => 10,
                'category_id' => 5,
                'title' => "标题五",
                "model" => 101,
                'desc' => "摘要",
            ],
            [
                "id" => 5,
                "view" => 10,
                'category_id' => 5,
                'title' => "标题五",
                "model" => 9,
                'desc' => "摘要",
            ],
        ];
        // 现在我要取出model 为101的，而且数量是2个，这里为啥这样做，我也不知道，因为我弄的是连表查询出来的数据，要把这个模型,拿出来
        
        $i = 0;//重新定义坐标为0
        foreach ($arr as $k=>$v){
            if($v['model'] == 101){
                //取出前2条放在首页显示，其他的跟原有数据正常排序
                $i++;
                if($i<=2){
                   $list['num'][] = $v; 
                }else{
                    //这里要跟下面的list一样，不然数据就会没了，这是剩下的101模型的数据
                    $list['list'][] = $v;
                }
            }else{
                $list['list'][] = $v;
            }
        }
        
        return $list;
