使用 PDO 向 MySQL 插入多条数据

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDBPDO";
 
try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
 
    // 开始事务
    $conn->beginTransaction();
    // SQL 语句
    $conn->exec("INSERT INTO MyGuests (firstname, lastname, email) 
    VALUES ('John', 'Doe', '[email protected]')");
    $conn->exec("INSERT INTO MyGuests (firstname, lastname, email) 
    VALUES ('Mary', 'Moe', '[email protected]')");
    $conn->exec("INSERT INTO MyGuests (firstname, lastname, email) 
    VALUES ('Julie', 'Dooley', '[email protected]')");
 
    // 提交事务
    $conn->commit();
    echo "新记录插入成功";
}
catch(PDOException $e)
{
    // 如果执行失败回滚
    $conn->rollback();
    echo $sql . "<br>" . $e->getMessage();
}
 
$conn = null;
?>
