我正在尝试使用一个带有文本区域的表单，我将在其中放置一些电子邮件。提交表单后，phpmailer.php必须连接到smtp。然后，对于文本区域中的每一行/电子邮件，它都会发送一封电子邮件。
有没有一种方法可以做到这一点，而不必为每一行/电子邮件打开smtp连接？
这是phpmailer:中的代码
try {
//Server settings
$mail->SMTPDebug = SMTP::DEBUG_SERVER; // Enable verbose debug output
$mail->isSMTP(); // Send using SMTP
$mail->Host = 'smtp.example.com'; // Set the SMTP server to send through
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'user@example.com'; // SMTP username
$mail->Password = 'secret'; // SMTP password
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
$mail->Port = 587; // TCP port to connect to, use 465 for `PHPMailer::ENCRYPTION_SMTPS` above
//Recipients
$mail->setFrom('from@example.com', 'Mailer');
$mail->addAddress('joe@example.net', 'Joe User'); // Add a recipient
$mail->addAddress('ellen@example.com'); // Name is optional
$mail->addReplyTo('info@example.com', 'Information');
$mail->addCC('cc@example.com');
$mail->addBCC('bcc@example.com');
// Attachments
$mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
// Content
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
在这种情况下，您可以分解按表单发布的电子邮件，并将每个电子邮件添加为类似密件抄送的：
$_POST['emails'] =
'email1@example.com
email2@example.com
email3@example.com
email4@example.com
email5@example.com';
$emails=explode(PHP_EOL, $_POST['emails']);
foreach ($emails as $email) {
$mail->addBCC($email);
}
