如何显示每个帖子评论的输出（如果帖子包含评论）

Question

我有一条消息要发布，如果我发布了一条消息，那么其他人可以对我的消息发表评论，但是现在我得到的输出就像一条帖子中有3条评论，然后我得到的是，每条评论获得3条相同的消息。

表结构如下

event table

ev_id   ev_name     ev_user
  1        ABC         MN
  2        XYZ         AB
  3        PQR         EF

comment table

co_event_id     co_name     co_comment
     1             QR       Some Comment
     1             ST       Some Comment
     2             UV       Some Comment    

$Query = "SELECT event.*, comment.*  FROM event LEFT JOIN comment ON event.ev_id = comment.co_event_id";
$Result = $con->query($Query);

while ($row = $Result->fetch(PDO::FETCH_ASSOC)) {
    $res[$row["ev_id"]]['ev_id'] = $row["ev_id"];
    $res[$row["ev_id"]]['ev_name'] = $row["ev_name"];
    $res[$row["ev_id"]]['ev_user'] = $row["ev_user"];

    $res[$row["ev_id"]]['comment'][] = array(
        "co_event_id" => $row['co_event_id'],
        "co_name" => $row['co_name'],
        "co_comment" => $row['co_comment']
    );
}
