public $uid = "root";
public $pwd = "";

//执行SQL语句的方法，$type代表SQL语句的类型，0代表查询
public function Prepare($sql,$typepdo = 0,$db = "mydb",$fwq = "mysql")
{
$dsn = "$fwq:dbname=$db;host=$this->host";
$pdo = new PDO($dsn,$this->uid,$this->pwd);
$stm = $pdo->prepare($sql);
if($stm->execute())
{
if($typepdo == 0)
{
return $stm->fetchAll(PDO::FETCH_ASSOC);
}
else

echo "执行成功";
return $stm->execute();
