<?php

            $row = mysql_fetch_array($result);


        ?>
<table width="581" height="299" border="1">
  <tr>
    <td>Union Assurance Questionnaire</td>
  </tr>
  <tr>
    <td>1.<?php echo $row['questions']; ?>

    </td>
  </tr>
  <tr>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
  </tr>
</table>
  <?php
            $result = select("SELECT * FROM questions WHERE question_id=2");
            $row = mysql_fetch_array($result);


        ?>
<table width="581" height="299" border="1">

  <tr>
    <td>2.<?php echo $row['questions']; ?>

    </td>
  </tr>
  <tr>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
  </tr>
</table>

Answer 1

像这样使用

<?php
while($row = mysql_fetch_array($result))
{
?>
<table width="581" height="299" border="1">
<tr>
<td>Union Assurance Questionnaire</td>
</tr>
<tr>
<td>1.<?php echo $row['questions']; ?>

</td>
</tr>
<tr>
<td>&nbsp;</td>
</tr>
<tr>
<td>&nbsp;</td>
</tr>
</table>
<?php
}
?>

您必须使用while() loop来迭代所有可能的答案。
