Answer 1

This will create a multi-dimensional array from your database query, and then encode it as JSON.

$d = array();
while ($row = $stmt->fetch_assoc()) {
  $d[] = $row;
}
$json = json_encode($d);

Each $row will be an associative array of the data returned from the database. Assigning it to $d[] adds it as an indexed element of that container array.
