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 = $result->fetch_row())
        {
            echo "<option value=http://www.mamicode.com/‘{$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
