将数据库中的信息显示在网页上
用下拉列表的方式输出在网页上，都在php格式里面便可以输出：
<body>
<?php
$db = new mysqli("localhost","root","12345678","heiheihei");
$sql = "select * from student";
$result = $db->query($sql);
echo "<select>";
if($result)
{
while ($attr = $result->fetch_row())
{
echo "<option value='{$attr[0]}'> {$attr[1]}</option>";
}
}
echo "</select>";
利用表格的格式：
<body>
<table width="100%" border="1" cellpadding="0" cellspacing="0">
<tr>
<td>代号</td>
<td>名称</td>
<td>编号</td>
</tr>
<?php
$db = new MySQLi("localhost","root","12345678","heiheihei");
$sql = "select * from cou ";
$r = $db->query($sql);
if($r)
{
while ($attr = $r->fetch_row())
{
echo
"
<tr>
<td>{$attr[0]}</td>
<td>{$attr[1]}</td>
<td>{$attr[2]}</td>
</tr>";
}
}
?>
</table>
</body>
</html>
反正套路都差不多啦
