php - 多个表格回显未显示在页面中

Question

上面的代码旨在显示sql表中存储的信息。一切都与表中的标题相对应并且顺序正确。然而，它所在的页面仅显示前两列，而不显示其他列。一切看起来似乎都是为了我。我的说法有错吗？

<?php
    $con=mysqli_connect("xxx","y","y","yyyy");
    // Check connection
    if (mysqli_connect_errno())
      {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
      }

    $result = mysqli_query($con,"SELECT * FROM tripdata ");

    while($row = mysqli_fetch_array($result))
      {
      echo $row['trip_id'] . " " . $row['image'] . " " . $row['date'] . " " . $row['destination'] . " " . $row['hl'] . " " . $row['cost'] . " " . $row['blurb'] . " " . $row['whatinc'] . " " . $row['whatopt'] . " " . $row['itin'] . " " . $row['depinfo'] . " " . $row['ppcode']; 
      echo "<br>";
      }

    mysqli_close($con);
    ?>

也许你可以尝试使用 assoc

while($row = mysqli_fetch_assoc($result))
  {
  echo $row['trip_id'] . " " . $row['image'] . " " . $row['date'] . " " . $row['destination'] . " " . $row['hl'] . " " . $row['cost'] . " " . $row['blurb'] . " " . $row['whatinc'] . " " . $row['whatopt'] . " " . $row['itin'] . " " . $row['depinfo'] . " " . $row['ppcode']; 
  echo "<br>";
  }

我经常用这个，没问题

assoc是基于字段名的索引名 但数组是基于数字 (0, 1, 2, 3)
