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

<tr>

</tr>
<tr>

</tr>
</table>
推荐答案
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> </td>
</tr>
<tr>
<td> </td>
</tr>
</table>
<?php
}
?>
您必须使用 while() 循环
来迭代所有可能的答案.
You have to use while() loop
for iterating all possible answers.
