将数组转换为用于在PHPMailer中发送的变量

<?php
require 'PHPMailer/PHPMailerAutoload.php';

// 创建邮件信息数组
$mailInfo = array(
    'to' => 'recipient@example.com',
    'from' => 'sender@example.com',
    'subject' => 'Hello from PHPMailer',
    'body' => 'This is the body of the email.',
    'attachment' => '/path/to/attachment.pdf'
);

// 将数组转换为JSON格式的字符串
$mailInfoJson = json_encode($mailInfo);

// 创建PHPMailer实例
$mail = new PHPMailer;

// 配置SMTP服务器
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your_username';
$mail->Password = 'your_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

// 设置发件人
$mail->setFrom($mailInfo['from'], 'Sender Name');

// 设置收件人
$mail->addAddress($mailInfo['to'], 'Recipient Name');

// 设置邮件主题
$mail->Subject = $mailInfo['subject'];

// 设置邮件正文
$mail->Body = $mailInfo['body'];

// 将邮件内容设置为HTML格式（可选）
$mail->isHTML(true);

// 添加附件
$mail->addAttachment($mailInfo['attachment']);

// 发送邮件
if (!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent.';
}
