Answer 1

Add JSON_NUMERIC_CHECK (integer) when encode in json.

JSON_NUMERIC_CHECK (integer) : Encodes numeric strings as numbers

$query = $this->db->query($selectQuery);
    $totalInvoice = array();
    foreach ($query->result() as $row)
    {
        $totalInvoice[] = $row->total;
    }
    print_r(json_encode($totalInvoice, JSON_NUMERIC_CHECK);
