有没有办法返回刚刚用PHP在MySQL中创建的行的id？

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接
if ($conn->connect_error) {
  die("连接失败: " . $conn->connect_error);
}
?>

<?php
// 插入数据
$sql = "INSERT INTO MyTable (column1, column2) VALUES ('value1', 'value2')";
if ($conn->query($sql) === TRUE) {
  // 获取刚刚插入行的ID
  $last_id = $conn->insert_id;
  echo "新记录插入成功，ID为: " . $last_id;
} else {
  echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>
