这段代码如何在tp3.2中实现??请大神指点迷津!一定要对数据类型进行判断!

$mysqli=new mysqli("localhost","root","snail","mysqldb");
$sql="update shop set name=?,price=? where id=?";
$stmt=$mysqli->prepare($sql);

//给每个占位符？传值（也叫参数绑定） i(整型) d(double) s(string) b(二进制，如图片、声音)
$stmt->bind_param("sdi",$name,$price,$id);

$name="zhangsan11111111";
$price=525.15;
$id=121;

$stmt->execute();
