Question

我正在尝试使用此代码制作评论页，但最终会收到错误。

以下是代码：

 $query = ("SELECT * FROM comment ORDER BY id DESC");

    $getquery = $connection->query($query);

    while($rows = ($getquery))
    {

        $id = $rows['id'];
        $names = $rows['name'];
        $comment = $rows['comment'];

        echo $name . '<br/>' . $comment . '<br/>' . '<br/>' ;
    }

这是错误：

PHP致命错误：未捕获错误：无法在E：\ utsdata \ 2T \ 2107982859 \ comment.php：61
中使用PDOStatement类型的对象作为数组

第61行是：$id = $rows['id'];

Answer 1

1）改变

$getquery = $connection->query($query);

要

$getquery = $connection->prepare($query);

2）改变

 while($rows = ($getquery))

要

while ($rows = $getquery->fetch(PDO::FETCH_BOTH)) {

3）添加$getquery->execute();

更新代码

$query = ("SELECT * FROM comment ORDER BY id DESC");

$getquery = $connection->prepare($query);
$getquery->execute();
while($result = $getquery->fetch(PDO::FETCH_BOTH);)
{

    $id = $rows['id'];
    $names = $rows['name'];
    $comment = $rows['comment'];

    echo $name . '<br/>' . $comment . '<br/>' . '<br/>' ;
}
