Answer 1

For what I know you need to use the column name in SQL.

Here is a solution that might help you to solve your problem Is it possible to SQL Update using row and column numbers?

Answer 2

Create an array that maps column numbers to names:

$cols = array('id', 'name', 'sport', ...);

Then when you're updating the row, you can do:

$col_name = $cols[$col_number];
$sql = "UPDATE yourTable SET `$col_name` = :value";
$stmt = $conn->prepare($sql);
$stmt->bindValue(':value', $col_value);
$stmt->execute();
