如何在while函数中设置foreach中的Increment id

Question

here is my code

if (($handle = fopen("example.csv", "r")) !== FALSE) 
{
    $row = 1;
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) 
    {
         $prod_startid=1;
         foreach ($Prod_op_reindex as $size_op_key => $size_op_value) 
         {
            echo  $prod_startid;
         }

    }
}

i want $prod_startid can Increment in foreach example: first time foreach the $prod_startid will be 1 2 3 4,

then after while function,in foreach the $prod_startid will be 5 6 7...

thanks everyone!

update: the arrays not the same,because some array have empty value ,so i have to use array_values function, for example:

Array ( [1] => XXS [2] => XS [3] => S [4] => M [5] => L [6] => XL [7] => XXL )

Array ( [1] => M [2] => L [3] => XL )

do you want this:

if (($handle = fopen("example.csv", "r")) !== FALSE) {
$row = 1;
$counter = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$prod_startid=$counter+1;
foreach ($Prod_op_reindex as $size_op_key => $size_op_value) {
   echo  $prod_startid;
    $prod_startid++;
    $couter = $prod_startid;
   }
 }
}
