题目做法：
建立数据库
封装类文件：
class fengzhuang
{
public $host="localhost";
public $uid="root";
public $pwd="159357";
public $sjkname="housedb";
//返回二维数组
function query($sql,$type=1)
{
$db = new MySQLi($this->host,$this->uid,$this->pwd,$this->sjkname);
$reslut = $db->query($sql);
if($type==1)
{
return $reslut->fetch_all();
}
else
{
return $reslut;
}
}
//返回关联数组
function glquery($sql,$type=1)
{
$db = new MySQLi($this->host,$this->uid,$this->pwd,$this->sjkname);
$reslut = $db->query($sql);
if($type==1)
{
$attr = array();
while($a = $reslut->fetch_assoc()) //取一条
{
$attr[] = $a;
}
return $attr;
}
else
{
return $reslut;
}
}
//返回接字符串
function zfcquery()
{
$db = new MySQLi($this->host,$this->uid,$this->pwd,$this->sjkname);
$reslut = $db->query($sql);
if($type=1)
{
$attr = $reslut->fetch_all(); //二维数组不能用implode
$atr = "";
foreach($attr as $v)
{
$str .= implode("^",$v);
$str .= "|";
}
return substr($str,0,strlen($str)-1);
}
else
{
return $reslut;
}
}
}
