在 PHP Mailer 中发送多封邮件答案

【问题标题】：Sending Multiple Mails In PHP Mailer在 PHP Mailer 中发送多封邮件

【问题描述】：

我一直在编写一个使用 PHP 邮件程序发送电子邮件的触发器。代码的问题在于它向单个收件人发送多封邮件。我什至尝试使用function singleTo，但即使这样似乎也不起作用。

$mail = new PHPMailer();

for($i = 0; $i <= sizeof($emailid); $i++)   {
    $mail->WordWrap = 50;                              
    $mail->IsHTML(true);                                 
    $mail->SingleTo = true;
    $mail->AddAddress($emailid[$i],$name[$i]);
    $mail->Subject = 'Some Subject';
    $mail->Body    = "Some Body";
    $mail->AltBody = "Some Body";

    $errornumber[$i] = 1;

    if(!$mail->Send()) {
       $errorinfo[$i] = $mail->ErrorInfo;
       $errornumber[$i] = 0;
    }
}

【问题讨论】：

$emailid[$i]和$name[$i]的值是多少？
sizeof($emailid) 的值是多少？
这些是邮件 ID 和他们的名字@jterry
这将是我必须邮寄给的人数。每次都不一样。 @无情

【解决方案1】：

AddAddress() 只是在地址数组的末尾添加一个新地址。如果您想按地址发送单独的电子邮件，则必须在每次迭代时清除该列表，例如

for(...) {
   $mail->AddAddress(...);
   $mail->send();
   $mail->ClearAddresses();  // <---you need this line.
}

如果单个用户正在接收多封电子邮件，那么您需要一些代码来检测您何时已经发送了一封电子邮件，例如：

$sent = array();
for(...) {
   if (isset($sent[$email[$i]])) {
      continue; // check if sent already, skip if so
   }
   ...
   if ($mail->send()) {
     $sent[$email[$i]] = true; // flag address as already sent
   }
}

我喜欢这个答案，因为如果您将相同的电子邮件发送给不同的收件人，则确实不需要重建电子邮件......您只需要更改收件人即可。 +1 谢谢！

代码示例为here

$mail = new PHPMailer();

$body = file_get_contents('contents.html');

$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->SMTPKeepAlive = true; // SMTP connection will not close after each email sent, reduces SMTP overhead
$mail->Port = 25;
$mail->Username = 'yourname@example.com';
$mail->Password = 'yourpassword';
$mail->setFrom('list@example.com', 'List manager');
$mail->addReplyTo('list@example.com', 'List manager');

$mail->Subject = "PHPMailer Simple database mailing list test";

//Same body for all messages, so set this before the sending loop
//If you generate a different body for each recipient (e.g. you're using a templating system),
//set it inside the loop
$mail->msgHTML($body);
//msgHTML also sets AltBody, so if you want a custom one, set it afterwards
$mail->AltBody = 'To view the message, please use an HTML compatible email viewer!';

//Connect to the database and select the recipients from your mailing list that have not yet been sent to
//You'll need to alter this to match your database
$mysql = mysql_connect('localhost', 'username', 'password');
mysql_select_db('mydb', $mysql);
$result = mysql_query("SELECT full_name, email, photo FROM mailinglist WHERE sent = false",   $mysql);
while ($row = mysql_fetch_array($result)) {
      $mail->addAddress($row['email'], $row['full_name']);
      $mail->addStringAttachment($row['photo'], 'YourPhoto.jpg'); //Assumes the image data is stored in the DB

      if (!$mail->send()) {
         echo "Mailer Error (" . str_replace("@", "&#64;", $row["email"]) . ') ' . $mail->ErrorInfo . '<br />';
         break; //Abandon sending
      } else {
            echo "Message sent to :" . $row['full_name'] . ' (' . str_replace("@", "&#64;", $row['email']) . ')<br />';
            //Mark it as sent in the DB
            mysql_query(
             "UPDATE mailinglist SET sent = true WHERE email = '" . mysql_real_escape_string($row['email'], $mysql) . "'"
            );
      }
      // Clear all addresses and attachments for next loop
      $mail->clearAddresses();
      $mail->clearAttachments();
}

我使用几乎相同的脚本，但我也设置了这个：

while(...)
{
  $mail = new PHPMailer(); //reset class instance to new one
  .....
  $mail->From = $fromAddress;   
  $mail->FromName = $fromAddress;
  $mail->AddAddress($toAdress);
  ....
}

.... - 与您的代码相同
