计数从2开始

Question

我不知道为什么，但它忽略了表格的第一行。 请帮忙：

    $row = 0;
    $con = mysqli_connect("localhost", "root", "root", "db");
    $query = "select * from user_accounts";
    $result = mysqli_query($con, $query);
    $row = mysqli_fetch_assoc($result);
    while($row = $result->fetch_array())
      {
      echo $row['ID'] . " " . $row['Username'];
      echo "<br />";
      }

Answer 1

有两件事，你要声明一个不需要的变量（$row = 0;）并且你要取两次，你不应该这样做：

$con = mysqli_connect("localhost", "root", "root", "db");
$query = "select * from user_accounts";
$result = mysqli_query($con, $query);
while($row = mysqli_fetch_assoc($result))
  {
  echo $row['ID'] . " " . $row['Username'];
  echo "<br />";
  }

Answer 2

$row = mysqli_fetch_assoc($result);
while($row = $result->fetch_array())

因此，您获取一个，忽略它然后继续提取
