<?php//连接数据库 //include引入方法include ("db.class.php");
//也可以写成include("./db.class.php")/include("../db.class.php")
//造一个对象
$db = new db();
//开始写语句
$sql = "select * from house";
//执行
$arr = $db->Query($sql);
foreach($arr as $v)
{
echo "
<tr>
<td>{$v}</td>
<td>{$v}</td>
<td>{$v}</td>
<td>{$v}</td>
<td>{$v}</td>
<td>{$v}</td>
<td>{$v}</td>
</tr>
";
