通过phpMailer从数据库中发送包含图像的电子邮件最常见的方式是什么？

<?php
require 'vendor/autoload.php'; // 引入phpMailer库

// 连接到数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

// 检索图像数据
$sql = "SELECT image_path FROM images WHERE id = 1";
$result = $conn->query($sql);
$row = $result->fetch_assoc();
$imagePath = $row['image_path'];

// 创建电子邮件
$mail = new PHPMailer\PHPMailer\PHPMailer();

// 设置电子邮件参数
$mail->setFrom('sender@example.com', 'Sender Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Email with Image Attachment';
$mail->Body = 'This email contains an image attachment.';

// 添加图像附件
$mail->addAttachment($imagePath);

// 发送电子邮件
if ($mail->send()) {
    echo 'Email sent successfully.';
} else {
    echo 'Error sending email: ' . $mail->ErrorInfo;
}

// 关闭数据库连接
$conn->close();
?>
