Call to undefined method mysqli_stmt::get_result() with mysqlnd enabled

Question

Initially I had this error saying Call to undefined method mysqli_stmt::get_result() Then after searching I found out that I have to enable mysqlnd driver for that. I using godaddy hosting site and I have enabled the mysqlnd driver but I am still facing the same issue. I have many function with get_result so solving each and one of em with bind_result is gonna be very time consuming and hectic for me. How can I fix this issue Let's say I have this query

$stmt = $this->conn->prepare("SELECT * FROM registeration_table WHERE phone = ?");
            $stmt->bind_param("s", $phone);
            $stmt->execute();
            $user = $stmt->get_result()->fetch_assoc();
            $stmt->close();
            return $user;

To resolve this error I have gone throught his link Stackoverflow link And implement this function

    public function get_result($Statement) {
    $RESULT = array();
    $Statement->store_result();
    for ( $i = 0; $i < $Statement->num_rows; $i++ ) {
        $Metadata = $Statement->result_metadata();
        $PARAMS = array();
        while ( $Field = $Metadata->fetch_field() ) {
            $PARAMS[] = &$RESULT[ $i ][ $Field->name ];
        }
        call_user_func_array( array( $Statement, 'bind_result' ), $PARAMS );
        $Statement->fetch();
    }
    return $RESULT;
}

Thank you.
