                $phone = $getData[2];
                $status = $getData[3];
                // If user already exists in the database with the same email
                $query = "SELECT id FROM users WHERE email = '" . $getData[1] . "'";
                $check = mysqli_query($conn, $query);
                if ($check->num_rows > 0)
                {
                    mysqli_query($conn, "UPDATE users SET name = '" . $name . "', phone = '" . $phone . "', status = '" . $status . "', created_at = NOW() WHERE email = '" . $email . "'");
                }
                else
                {
                     mysqli_query($conn, "INSERT INTO users (name, email, phone, created_at, updated_at, status) VALUES ('" . $name . "', '" . $email . "', '" . $phone . "', NOW(), NOW(), '" . $status . "')");
                }
            }
            // Close opened CSV file
            fclose($csvFile);
