PHP mail() BCC - 仅显示 To : header 中的最终收件人地址

转载作者：可可西里更新时间：2023-10-31 23:17:50

我正在尝试使用 PHP mail() 密件抄送数据库中的订阅者列表。一切正常，但我遇到了一个困扰我一上午的问题。我可以使用 BCC 发送列表，但无法将接收端电子邮件地址附加到 deader“To:”。

例如，我将列表发送到以下电子邮件地址 (test1@example.com、test2@example.com 和 test3@example.com)。每个电子邮件地址都会收到一封电子邮件，而其他电子邮件地址由于密件抄送而被隐藏。

我的问题是在标题中，“收件人:”在列表的所有接收端都显示为空白。我理解并知道标题不会显示，因为我在外发邮件中只有密件抄送标题。我已尝试 for 循环处理该过程，但我收到了所有电子邮件，并在一个循环中收到了一封针对该地址的电子邮件。

这是我的工作代码:工作代码包括我试图解决 To: header 的循环。我可以发送电子邮件，但我会收到所有发送的电子邮件。

<?php

/*
   Gathers the number of rows within the database. Used for the loop that displays the entire list in the BCC. 
*/

   session_start();
   include_once '../dbconnect.php';
   $result = mysql_query("SELECT * FROM news");
   $num_rows = mysql_num_rows($result);
   $rows = $num_rows;

/*
   Requests the list from the database, please the list in a loop, displays the list only once, and places list in an operator.
*/

   $result = mysql_query("SELECT * FROM `news`");
     while($row = mysql_fetch_array( $result )) {
       for ($x = 1; $x <= 1; $x++) {
         $contacts.= "".$row['email'].",";
       }
     }

/*
   ATTEMPT (It works... sort of): Sends mail to the list using BCC, displays the ONLY receivers email address in the To: header
*/

   $result = mysql_query("SELECT * FROM `news`");
     while($row = mysql_fetch_array( $result )) {
       for ($x = 1; $x <= 1; $x++) {
         $receiver= "".$row['email']."";

         $to = "$receiver";
         $subject = 'Test Email';
         $headers = "From: example@example.com\r\n";
         $headers .= "BCC: $contacts";

         $headers .= "MIME-Version: 1.0\r\n";
         $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
         $message = '<html><body>';
         $message .= '<h1 style="">Test Message</h1>';
         $message .= '</body></html>';
         mail($to,$subject, $message, $headers);
      }
    }
?>

我的一般想法是循环，但我找不到真正完全解决这个问题的解决方案，通过 BBC 到列表并在 To: 标题中仅显示接收端电子邮件地址。有什么想法或想法吗？

使用 SMTP 服务器更新

我一直在尝试使用在此线程中找到的解决方案并将其应用于 SMTP 服务器。使用 SendGrid 发送消息是理想的选择。我想出了以下选项，但脚本似乎只将一条消息发送到数据库中的一个地址，而不是所有地址。

<?php
require_once "Mail.php";

$sub = $_POST['subject'];
$ttl = $_POST['title'];
$img = $_POST['image'];
$bdy = $_POST['body'];
$lk = $_POST['link'];

mysql_connect("", "", "") or die(mysql_error()) ; 
   mysql_select_db("") or die(mysql_error()) ; 

  $result = mysql_query("SELECT `email` FROM news");

  $num_rows = mysql_num_rows($result);

  $receivers = array();
  while ($row = mysql_fetch_array($result)) {
    $receivers[] = $row['email'];
  }

  foreach ($receivers as $receiver) { }

$from = "test@example.com";
$to = $receiver;
$subject = $sub;
$mime = "1.0";
$ctype = "text/html; charset=ISO-8859-1";
$body = '
<html><body>
<p>Test Message!</p>
</body></html>
';

$host = "";
$port = "";
$username = "";
$password = "";

$headers = array ('From' => $from,
  'To' => $to,
  'Subject' => $subject,
  'MIME-Version' => $mime ,
  'Content-Type:' => $ctype);

$smtp = Mail::factory('smtp',
  array ('host' => $host,
    'port' => $port,
    'auth' => true,
    'username' => $username,
    'password' => $password));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
  echo("<p>" . $mail->getMessage() . "</p>");
} else {
  echo("<p>Message successfully sent!</p>");
}
?>

最佳答案

该代码包括对您的代码的一些一般改进。我添加了内联评论来解释我所做的事情。

<?php

  // General thing: If you do not need a session, do not start one ;)
  session_start();

  include_once '../dbconnect.php';

  // Select only what you really need from the table. This saves you memory
  // and it speeds up the query.
  $result = mysql_query("SELECT `email` FROM news");

  // You are not using these numbers in the script you showed us. I am just
  // leaving them in here to show you, how you can reuse the "$result"
  // variable without querying the database again.
  $num_rows = mysql_num_rows($result);

  // We are reusing the "$result" here without re-querying the database, which
  // speeds the whole process up and takes load away from the database. We are
  // storing all receivers in a dedicated variable, to reuse them later on.
  $receivers = array();
  while ($row = mysql_fetch_array($result)) {
    $receivers[] = $row['email'];
  }

  // Now, instead of querying the database again, we are using our stored mail
  // addresses in "$receivers" to send the emails one by one. We could have
  // done this part in the "while" loop before, but I wanted to stay close to
  // your code, so you would recognize it ;)
  foreach ($receivers as $receiver) {
    // I have removed the "for" loop here, because it runs only once. If a loop
    // only runs once and you control all its input, you really do not need a
    // loop at all (except some exceptions, just in case someone knows one^^).

    // You can actually just put the value of $receiver in $to. PHP is pretty
    // good at typecasting of scalar types (integers, strings etc.), so you do
    // not need to worry about that.
    $to = $receiver;

    $subject = 'Test Email';

    // I am putting the headers into an array and implode them later on. This
    // way we can make sure that we are not forgetting the new line characters
    // somewhere.
    $headers = array(
      "From: example@example.com",
      "MIME-Version: 1.0",
      "Content-Type: text/html; charset=ISO-8859-1",
      // I have removed the "BCC" header here, because this loops send out an
      // email to each user seperately. It is basically me sending an email to
      // you. Afterwards I copy&paste all the content to another new mail and
      // send it to another fella. You would never know that you both got the
      // same mail ;)
    );

    $message = '<html><body>';
    $message .= '<h1 style="">Test Message</h1>';
    $message .= '</body></html>';

    // Imploding the headers.
    $imploded_headers = implode("\r\n", $headers);

    mail($to, $subject, $message, $imploded_headers);
  }
