Question

我需要附上两张桌子。第一循环是完美的，但第二个For-loop表进入了Bottom。我需要将那个底部表附加到前一个表。任何人都可以解决这个问题吗？任何解决方案都将不胜感激，所以建议解决这个问题。

Answer 1

首先设置表格标题（<th>），然后设置表格主体，如果您希望所有标题显示为内联。

然后，您可以为两个表的行创建数组，并为每一行输出。

注意：如果您的$btc和$doge数组具有不同的行数或者行数不同，则可能需要创建第三个数组结合两者，然后循环。

echo '<table border="1">
      <tr>
          <th colspan="2">BTC EXCHANGE</th>
          <th colspan="2">DOGE EXCHANGE</th>
      </tr>';

// prepare the rows
$btc = array();
$doge = array();

if($jsons)
{
  foreach ($jsons->Data as $sam)
  {
     $number = (float) $sam->AskPrice;
     array_push($btc, array($sam->Label, number_format($number,8) ));
  }

  foreach ($jsonsz->Data as $sam)
  {
     $number = (float) $sam->AskPrice;
     array_push($doge, array($sam->Label, number_format($number,8) ));
  }

  // assuming count($btc) and count($doge) are the same
  for($i=0; $i< count($btc); $i++)
  {
      echo '<tr>
             <td>'.$btc[i][0].'</td>
             <td>'.$btc[i][1].' ($'.number_format($btc[i][1] * $usd, 6).')</td>
             <td>'.$doge[i][0].'</td>
             <td>'.$doge[i][1].' ($'.number_format($doge[i][1] * $usd, 6).')</td> 
          </tr>';
  }
}
echo '</table>';
?>

Answer 2

您有两个<th>单元格应位于表格行<tr>中：

echo "<th>BTC EXCHANGE</th>";

和

echo "<th>DOGE EXCHANGE</th>";

将您的代码更改为：

echo "<tr><th>BTC EXCHANGE</th></tr>";

和

echo "<tr><th>DOGE EXCHANGE</th>";

HTML表格将行更改为列For循环
