Question

我有7个由mysql提取的数组并且它正常工作每个数组都有9行是city_names但是其中一个数组只有7行，因为结果中的两个值为null。这会在csv中转储文件时导致混淆。我使用下面的代码。有没有办法按城市名称检查它而不使用foreach for eact array？

        for($i=0 ; $i <= $count-2 ; $i++)
        {
            $data[] = $all_restaurants_opr_no_temp_off[$i]['city_name'];

            $data[] = $all_restaurants_opr[$i]['total'];


            $data[] = $all_restaurants_opr_no_temp_off[$i]['total'];



            $data[] = $restaurants_opr_temp_off[$i]['total'];

                $data[] = $restaurants_opr_operations_closed[$i]['total'];

                $data[] = $restaurants_opr_automated[$i]['total'];

                $data[] = $restaurants_opr_automated_working[$i]['total'];

                $data[] = $restaurants_opr_online_payment[$i]['total'];

                $data[] = $restaurants_opr_online_payment_with_tempoff[$i]['total'];

                $data[] = $restaurants_opr_atleast_one_order[$i]['total'];

            fputcsv($fp, $data,",");
            unset($data);
            }

我不确定我是否理解100％的问题，但也许您可以测试每个值是否为null并在其中放置默认值（例如，对于此行，您可以使用上面的内容）你的for循环：

foreach($badArray as $b){
  $reformattedArray[$b['city_name']] = $b['total'];
}

然后在for循环中用这个替换坏数组行

data[] = is_null($reformattedArray[$all_restaurants_opr_no_temp_off[$i]['city_name']]) ? 'Default' : $reformattedArray[$all_restaurants_opr_no_temp_off[$i]['city_name']];

在csv文件中转储数组时数据不匹配
