使用 MySQLi 和 PDO 向 MySQL 插入数据

1、(MySQLi - 面向对象)

connect_error) {
die("连接失败: " . $conn->connect_error);
}

$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]')";

if ($conn->query($sql) === TRUE) {
echo "新记录插入成功";
} else {
echo "Error: " . $sql . "
" . $conn->error;
}

 $conn->close();
?>

2、(MySQLi - 面向过程)

" . mysqli_error($conn);
}

 mysqli_close($conn);
?>

3、 (PDO)

setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "INSERT INTO MyGuests3 (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]')";
// 使用 exec() ，没有结果返回
$conn->exec($sql);
echo "新记录插入成功";
}
catch(PDOException $e)
{
echo $sql . "
" . $e->getMessage();
}

$conn = null;
?>
