<?php
require 'vendor/autoload.php'; // 導入PHPMailer庫

use PHPMailerPHPMailerPHPMailer;
use PHPMailerPHPMailerSMTP;
use PHPMailerPHPMailerException;

$mail = new PHPMailer(true);
$mail->isSMTP(); // 使用SMTP協(xié)議發(fā)送郵件
$mail->SMTPDebug  = 0; // 關閉調(diào)試輸出
$mail->Host       = 'smtp.example.com'; // 郵件服務器地址
$mail->SMTPAuth   = true; // 開啟SMTP驗證
$mail->Username   = 'your-email@example.com'; // 郵箱用戶名
$mail->Password   = 'your-password'; // 郵箱密碼
$mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS; // 使用SMTPS加密
$mail->Port       = 465; // 郵件服務器端口號

// 設置收件人、發(fā)件人和郵件內(nèi)容
$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('to@example.com', 'Recipient Name');
$mail->Subject = 'Test Email';
$mail->Body    = 'This is a test email';

// 異步發(fā)送郵件
$mail->sendAsync(function ($result) {
    if ($result) {
        echo '郵件發(fā)送成功！';
    } else {
        echo '郵件發(fā)送失?。? . $mail->ErrorInfo;
    }
});

echo '繼續(xù)執(zhí)行其他任務...';
?>

SMTP ?? ??, ??? ??? ?? ? ???? ?? ??? ? ?? ?? ??? ?????. ?? ?? ?? ??, ??? ??, ??? ??, ??? ?????. ????? sendAsync ???? ???? ???? ??? ???? ??? ? ???? ?? ??? ?????. ?? ????? ???? ????? ?????? ??? ?? ?? ??? ??? ? ????. sendAsync方法發(fā)送郵件并傳入一個回調(diào)函數(shù)，該回調(diào)函數(shù)在郵件發(fā)送完成后被調(diào)用。在回調(diào)函數(shù)中，我們可以根據(jù)郵件是否發(fā)送成功來執(zhí)行相應的操作。

三、使用Swift Mailer庫發(fā)送異步郵件
除了PHPMailer，Swift Mailer也是一個功能強大的郵件發(fā)送庫，也支持異步發(fā)送郵件。下面是一個使用Swift Mailer庫發(fā)送異步郵件的例子：

<?php
require 'vendor/autoload.php'; // 導入Swift Mailer庫

// 創(chuàng)建Transport對象
$transport = new Swift_SmtpTransport('smtp.example.com', 465, 'ssl');
$transport->setUsername('your-email@example.com')
          ->setPassword('your-password');

// 創(chuàng)建Mailer對象
$mailer = new Swift_Mailer($transport);

// 創(chuàng)建郵件對象
$message = new Swift_Message();
$message->setSubject('Test Email')
        ->setFrom(['from@example.com' => 'Your Name'])
        ->setTo(['to@example.com' => 'Recipient Name'])
        ->setBody('This is a test email');

// 發(fā)送異步郵件
$mailer->send($message, $failedRecipients);

if ($failedRecipients) {
    echo '郵件發(fā)送失敗：' . implode(', ', $failedRecipients);
} else {
    echo '郵件發(fā)送成功！';
}

echo '繼續(xù)執(zhí)行其他任務...';
?>

在上述代碼中，我們首先導入Swift Mailer庫，并創(chuàng)建一個Transport對象。通過設置SMTP服務器地址、用戶名和密碼等信息來配置Transport。然后，創(chuàng)建一個Mailer對象，并將Transport對象傳給它。接著，創(chuàng)建一個郵件對象，設置郵件的收件人、發(fā)件人、主題和正文。最后，調(diào)用Mailer的send方法發(fā)送郵件，并傳入一個參數(shù)$failedRecipients來接收發(fā)送失敗的收件人列表。根據(jù)$failedRecipients
