1.造PDO对象
$dsn = "mysql:dbname=mydb;host=localhost";
$pdo = new PDO($dsn,"root","123");

2.写一个预处理语句
$sql = "insert into nation values(?,?)";

3.将预处理语句扔到服务器等待执行，返回PDOStatement对象
$stm = $pdo->prepare($sql);

4.第二次将变量（参数）扔到服务器的SQL语句相应位置,给预处理语句绑定参数
$stm->bindParam(1,$code);
$stm->bindParam(2,$name);
$code = "n085";
$name = "天族";

5.定义索引数组
$arr = array("n082","数据");

6.执行
$stm->execute($arr);

$pdo = new PDO($dsn,"root","123");

2.预处理语句
$sql = "insert into nation values(:code,:name)";
$stm = $pdo->prepare($sql);

3.绑定参数
$stm->bindParam(":code",$code);
$stm->bindParam(":name",$name);
$code = "n070";
$name = "神族";

4.造一个数组
$arr = array("code"=>"n071","name"=>"胜率");

5.执行
$stm->execute($arr);
