在PHP中使用fputcsv水平移动指针

Question

I am trying to write 2 arrays to csv file using fputcsv.

But the problem is when writing the second array it goes to the end of the file and starts from there.

So basically I have these 2 sections to write in a csv file and it's writing in the following way

ID      Name1

1       AAA
2       BBB

Name2

CCC
DDD

What I want

ID      Name1      Name2

1       AAA        CCC
2       BBB        DDD

My code is

fputcsv($fh, array("ID","Name1"));
while($row = mysqli_fetch_array($weekly1, MYSQLI_NUM))
{
    fputcsv($fh, array($row[0],$row[1]));
}

fputcsv($fh, array("Name2"));
while($row = mysqli_fetch_array($weekly2, MYSQLI_NUM))
{
    fputcsv($fh, array($row[1]));
}

Is there any way to overcome this problem. Any help or suggestion is highly welcomed.Thanks in advance.

First you should store ID and NAME1 in an array and only after getting NAME2 save to csv:

fputcsv($fh, array("ID","Name1","Name2"));
$rows = array();
while($row = mysqli_fetch_array($weekly1, MYSQLI_NUM))
{
    $rows[] = array($row[0],$row[1]));
}

$i = 0;
while($row = mysqli_fetch_array($weekly2, MYSQLI_NUM))
{
    fputcsv($fh, array_merge($rows[$i], array($row[1])));
    $i++;
}
