虽然循环每次都会覆盖数据，但我该如何解决这个问题？

Question

我有以下问题。 我想用 Ajax 设置一个报告按钮，这会传递某些变量，如评论 ID、评论的创建者。

正如我所说，我已经使用 Ajax 实现了这一点，到目前为止一切都很好。

我的 PHP 代码在另一个 PHP 文件中作为 POST。

我有一个 While 循环，我在其中输出数据库中的所有数据。

现在我想通过 SESSION 保存和传递这些数据，但是这个数据每次都会被 While 循环覆盖，我该如何解决这个问题？

$stmt = $pdo->prepare("SELECT * FROM threadComments WHERE subThreadsID = ? ORDER BY created_at DESC ");
$stmt->execute([$page]);
while($row = $stmt->fetch()){
    $createdComments = $row['created_at'];
    $idComment = $row['id'];
    $userlike = $row['userlike'];
    $userid = $row['userid'];
    $username = $row['username'];
    $dateNow = date_create($createdComments, timezone_open('Europe/Berlin'));
    $timeNow = time();
    $seconds = strtotime($createdComments);
    $diffSeconds = $timeNow - $seconds;
    $date = date_format($dateNow, 'd.m.Y - H:i');

    $statement = $pdo->prepare("SELECT userid, userImage FROM users WHERE userid = ?");
    $statement->execute([$userid]);
    $rowImages = $statement->fetch();
    extract($rowImages);


    $string = $row['threadContent'];
    $string = convertHashtags($string);
    
    HTML /////

    $_SESSION['commentContent'] = $string;
    $_SESSION['commentCreaterID'] = $row['userid'];
    $_SESSION['commentID'] = $row['id'];

}
?>

将它们放入$_SESSION 中的数组中。将其设为关联数组，以便您可以使用 $_SESSION['comments'][$id] 获取特定评论 ID 的数据

$stmt = $pdo->prepare("SELECT * FROM threadComments WHERE subThreadsID = ? ORDER BY created_at DESC ");
$stmt->execute([$page]);
$_SESSION['comments'] = [];
while($row = $stmt->fetch()){
    $createdComments = $row['created_at'];
    $idComment = $row['id'];
    $userlike = $row['userlike'];
    $userid = $row['userid'];
    $username = $row['username'];
    $dateNow = date_create($createdComments, timezone_open('Europe/Berlin'));
    $timeNow = time();
    $seconds = strtotime($createdComments);
    $diffSeconds = $timeNow - $seconds;
    $date = date_format($dateNow, 'd.m.Y - H:i');

    $statement = $pdo->prepare("SELECT userid, userImage FROM users WHERE userid = ?");
    $statement->execute([$userid]);
    $rowImages = $statement->fetch();
    extract($rowImages);


    $string = $row['threadContent'];
    $string = convertHashtags($string);
    
    HTML /////

    $_SESSION['comments'][$row['id']] = [
        'content' => $string,
        'creatorID' => $row['userid'],
        'commentID' => $row['id']
    ];
}
