PHP如何利用循环输出数据库表中所有记录

<php
mysql_select_db("infosystem",
$link);
//选择数据库
$q
=
"SELECT

FROM
info";
//SQL查询语句
mysql_query("SET
NAMES
GB2312");
$rs
=
mysql_query($q,
$link);
//获取数据集
if(!$rs){die("Valid
result!");}
echo
"<table>";
echo
"<tr><td>部门名称</td><td>员工姓名</td><td>PC名称</td></tr>";
while($row
=
mysql_fetch_row($rs))
echo
"<tr><td>$row[1]</td><td>$row[2]</td><td>$row[3]</td></tr>";
//显示数据
echo
"</table>";
mysql_free_result($rs);
//关闭数据集

<php
$db=mysql_connect( 'localhost', '用户名', '密码' );
mysql_select_db('test',$db);
$query=mysql_query("select from test");
while($rs=mysql_fetch_array($query))
{
>
<table>
<tr>
<td><php echo $rs['id']></td>
<td><php echo $rs['title']></td>
<td><php echo $rs['content']></td>
</tr>
</table>
<php
}
>
