Php 页面中未显示多个表回声

上面的代码旨在显示存储在sql表中的信息。所有内容都与表中的标题相对应，并且顺序正确。但是，它所在的页面仅显示前两列，而不显示其他列。对我来说，一切似乎都井然有序。我的陈述错了吗

<?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);
    ?>

奇怪。请尝试执行循环：

do {    
  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>";

} while($row = mysqli_fetch_array($result));

do{
echo$row['trip_id']。$row['image']。$row['date']。$row['destination']。$row['hl']。$row['cost']。$row['blurb']。$row['whatopt']。$row['itin']。$row['depinfo']。$row['ppcode']；
回声“

}而（$row=mysqli_fetch_数组（$result））；

也许您可以尝试使用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>";
  }

while（$row=mysqli\u fetch\u assoc（$result））
{
echo$row['trip_id']。$row['image']。$row['date']。$row['destination']。$row['hl']。$row['cost']。$row['blurb']。$row['whatopt']。$row['itin']。$row['depinfo']。$row['ppcode']；
回声“
”；
}

我通常用这个，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）

。我的意思是它是前两列，而不是其余的。这真的很奇怪：$row=mysqli\u fetch\u数组（$result）；var_转储（$row）；您会看到其余的列吗？它实际上只是显示的第一列。这是主键在循环之前是否使用var_dump（$row）查看数组中的所有记录？试试Hans的建议：mysqli_fetch_assoc而不是mysqli_fetch_array不要在网上发布登录详细信息！！
