使用循环

Question

我总是无法理解如何使用循环正确生成无序列表。但现在我必须生成一个并将数据库中的数据插入其中。这就是我从数据库中检索数据的方法。

$sql_history = "SELECT * FROM transaction_summary WHERE transaction_Sender='$username' OR transaction_Recipient='$username' ORDER BY id DESC LIMIT 10";
$query = mysqli_query($db, $sql_history);
$row = mysqli_fetch_array($query);

$sender = $row['transaction_Sender'];
$recipient = $row['transaction_Recipient'];
$amount = $row['transaction_Amount'];

如何在无序列表中显示最新的10行？谢谢。

Answer 1

$row = mysqli_fetch_array($query);

上面的行将第一条记录分配给名为$ row的数组。您需要对查询返回的每条记录执行此操作。所以你应该这样做：

while($row = mysqli_fetch_array($query))
{
    $sender = $row['transaction_Sender'];
    $recipient = $row['transaction_Recipient'];
    $amount = $row['transaction_Amount'];       
}
