基础配置类

<?php
namespace App\Services;

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

订单状态邮件模板系统

1. 订单确认邮件

class OrderConfirmationEmail extends EmailService
{
    public function sendConfirmation(array $orderData, string $customerEmail)
    {
        try {
            $this->mailer->setFrom('noreply@yourstore.com', 'Your Store');
            $this->mailer->addAddress($customerEmail);
            $this->mailer->addReplyTo('service@yourstore.com', 'Customer Service');
            
            $this->mailer->Subject = '订单确认 - 订单号: ' . $orderData['order_number'];
            $this->mailer->isHTML(true);
            
            // 使用HTML模板
            $htmlContent = $this->buildConfirmationTemplate($orderData);
            $this->mailer->Body = $htmlContent;
            
            // 纯文本备用内容
            $this->mailer->AltBody = $this->buildTextConfirmation($orderData);
            
            $this->mailer->send();
            return true;
            
        } catch (Exception $e) {
            error_log("邮件发送失败: " . $this->mailer->ErrorInfo);
            return false;
        }
    }

                <tfoot>
                    <tr>

            </tr>";
        }
        return $rows;
    }
}

2. 支付成功邮件

class PaymentSuccessEmail extends EmailService
{
    public function sendPaymentSuccess(array $paymentData, string $customerEmail)
    {
        $this->mailer->Subject = '支付成功 - 订单号: ' . $paymentData['order_number'];
        $this->mailer->Body = $this->buildPaymentTemplate($paymentData);
        $this->mailer->AltBody = "您的订单{$paymentData['order_number']}已支付成功,金额: {$paymentData['amount']}元";
        
        return $this->sendEmail($customerEmail);
    }
}

3. 发货通知邮件

class ShippingNotificationEmail extends EmailService
{
    public function sendShippingNotification(array $shippingData, string $customerEmail)
    {
        // 添加物流单号附件
        if (!empty($shippingData['tracking_pdf'])) {
            $this->mailer->addStringAttachment(
                $shippingData['tracking_pdf'],
                'tracking_number.pdf'
            );
        }
        
        $this->mailer->Subject = '您的订单已发货';
        $this->mailer->Body = $this->buildShippingTemplate($shippingData);
        
        return $this->sendEmail($customerEmail);
    }
}

完整的订单邮件处理器

class OrderEmailHandler
{
    private $emailService;
    private $templatePath;

    public function __construct(EmailService $emailService, string $templatePath)
    {
        $this->emailService = $emailService;
        $this->templatePath = $templatePath;
    }

    public function handleOrderEvent(string $eventType, array $orderData)
    {
        $emailTemplate = $this->getTemplateForEvent($eventType);
        $customerEmail = $orderData['customer_email'];
        
        switch ($eventType) {
            case 'order_created':
                return $this->sendOrderConfirmation($orderData, $customerEmail);
                
            case 'payment_success':
                return $this->sendPaymentSuccess($orderData, $customerEmail);
                
            case 'order_shipped':
                return $this->sendShippingNotification($orderData, $customerEmail);
                
            case 'order_completed':
                return $this->sendOrderCompletion($orderData, $customerEmail);
                
            default:
                throw new \InvalidArgumentException("未知的订单事件类型: {$eventType}");
        }
    }

    private function sendOrderConfirmation(array $orderData, string $customerEmail): bool
    {
        $template = new OrderConfirmationEmail($this->emailService->getConfig());
        return $template->sendConfirmation($orderData, $customerEmail);
    }
}

SMTP服务器配置最佳实践

配置示例

$smtpConfig = [
    'host' => 'smtp.qq.com',
    'username' => 'your_email@qq.com',
    'password' => 'your_smtp_password',
    'port' => 465,
    'from_email' => 'noreply@yourdomain.com',
    'from_name' => 'Your Store',
    'reply_to' => 'service@yourdomain.com',
    'charset' => 'UTF-8',
    'encoding' => 'base64'
];

支持的SMTP服务商配置

服务商 Host Port Encryption
QQ邮箱 smtp.qq.com 465 SSL
163邮箱 smtp.163.com 465 SSL
Gmail smtp.gmail.com 587 TLS
阿里云企业邮 smtp.mxhichina.com 465 SSL
SendGrid smtp.sendgrid.net 587 TLS

高级功能实现

1. 邮件队列处理

class EmailQueueProcessor
{
    public function processQueue(int $batchSize = 50)
    {
        $pendingEmails = $this->getPendingEmails($batchSize);
        
        foreach ($pendingEmails as $email) {
            try {
                $success = $this->sendQueuedEmail($email);
                $this->updateEmailStatus($email['id'], $success);
            } catch (Exception $e) {
                $this->handleEmailError($email['id'], $e->getMessage());
            }
        }
    }
}

2. 邮件模板引擎集成

class TemplateRenderer
{
    public function render(string $templateName, array $data): string
    {
        $templateFile = $this->templatePath . '/' . $templateName . '.html';
        
        if (!file_exists($templateFile)) {
            throw new \RuntimeException("模板文件不存在: {$templateFile}");
        }
        
        $content = file_get_contents($templateFile);
        return $this->replacePlaceholders($content, $data);
    }

    private function replacePlaceholders(string $content, array $data): string
    {
        foreach ($data as $key => $value) {
            $placeholder = '{{' . $key . '}}';
            $content = str_replace($placeholder, $value, $content);
        }
        return $content;
    }
}

错误处理与日志记录

完整的错误处理机制

class EmailLogger
{
    public static function logSuccess(string $email, string $subject, string $messageId)
    {
        error_log(sprintf(
            "[SUCCESS] Email sent to %s: %s (Message-ID: %s)",
            $email,
            $subject,
            $messageId
        ));
    }

    public static function logError(string $email, string $subject, string $errorInfo)
    {
        error_log(sprintf(
            "[ERROR] Failed to send email to %s: %s - %s",
            $email,
            $subject,
            $errorInfo
        ));
    }

    public static function logWarning(string $email, string $subject, string $warning)
    {
        error_log(sprintf(
            "[WARNING] Email warning for %s: %s - %s",
            $email,
            $subject,
            $warning
        ));
    }
}

性能优化建议

1. SMTP连接复用

// 启用连接保持
$mail->SMTPKeepAlive = true;

// 批量发送时复用连接
public function sendBatchEmails(array $emails)
{
    $this->mailer->SMTPKeepAlive = true;
    
    foreach ($emails as $email) {
        $this->mailer->clearAddresses();
        $this->mailer->clearAttachments();
        
        // 配置新邮件
        $this->configureEmail($email);
        
        try {
            $this->mailer->send();
        } catch (Exception $e) {
            // 错误处理
        }
    }
    
    $this->mailer->smtpClose();
}

2. 异步处理

class AsyncEmailSender
{
    public function sendAsync(string $email, string $subject, string $body)
    {
        // 将邮件任务放入消息队列
        $this->queue->push(new EmailJob([
            'email' => $email,
            'subject' => $subject,
            'body' => $body
        ]));
    }
}

安全最佳实践

1. 输入验证与过滤

class EmailValidator
{
    public static function validateEmail(string $email): bool
    {
        return filter_var($email, FILTER_VALIDATE_EMAIL) !== false;
    }

    public static function sanitizeSubject(string $subject): string
    {
        return htmlspecialchars($subject, ENT_QUOTES, 'UTF-8');
    }

    public static function preventHeaderInjection(string $input): string
    {
        return str_replace(["\r", "\n"], '', $input);
    }
}

2. DKIM签名配置

// 配置DKIM签名
$mail->DKIM_domain = 'yourdomain.com';
$mail->DKIM_private = '/path/to/private/key';
$mail->DKIM_selector = 'default';
$mail->DKIM_passphrase = ''; // 如果私钥有密码
$mail->DKIM_identity = $mail->From;

测试与监控

单元测试示例

class OrderEmailTest extends TestCase
{
    public function testOrderConfirmationEmail()
    {
        $emailService = new EmailService($this->getTestConfig());
        $handler = new OrderEmailHandler($emailService);
        
        $orderData = [
            'order_number' => 'TEST123',
            'customer_email' => 'test@example.com',
            'total_amount' => '299.00',
            'items' => [
                ['name' => '测试商品', 'price' => '299.00', 'quantity' => 1, 'subtotal' => '299.00']
            ]
        ];
        
        $result = $handler->handleOrderEvent('order_created', $orderData);
        $this->assertTrue($result);
    }
}

监控指标

发送成功率 成功发送的邮件比例 > 99%
平均发送时间 从请求到发送完成的时间 < 2秒
