Data mismatch while dumping array in csv file - php

Question

I have 7 array fetched by mysql and its working correctly each array have exactly 9 rows which are city_names but one of the array has only 7 rows since two values on the results where null . This causes confunsion while dumping file in csv. I use the below code. Is there any way to check it by city name without using 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);
}

I'm not sure I understand the question 100%, but perhaps you can test each value if it is null and put a default value there if it is, for example, for this row, you could use this above your for loop:
foreach($badArray as $b){
$reformattedArray[$b['city_name']] = $b['total'];
}
then replace the bad array line with this in your for loop
data[] = is_null($reformattedArray[$all_restaurants_opr_no_temp_off[$i]['city_name']]) ? 'Default' : $reformattedArray[$all_restaurants_opr_no_temp_off[$i]['city_name']];
