Question

今天早上，我开始研究一个邮件系统，该邮件系统向多个地址发送邮件，并且只向最终用户显示一个地址，即时事通讯电子邮件。可以找到工作代码here。现在，我试图通过SMTP服务器传递循环。这是捆绑邮件以允许更安全的传递。我的问题是传递这些标题并获取消息以进入SMTP服务器。我使用PEAR获取对SendGrids SMTP的访问权限。我收到一条错误消息，指出＆＃34; $ header必须是数组 ＆＃34;。

我首先打破了Rackspace提供的这种模式。

<?php
require_once "Mail.php";

$from = "Bill Gates Jr. <billy@example.com>";
$to = "Steve Ballmer Sr. <Stevie@example.com>";
$subject = "Secrete Microsoft Project\r\n\r\n";
$body = "Yo this is a test message";

$host = "smtp.sendgrid.net";
$port = "587";
$username = "Account_Username";
$password = "Account_Password";

$headers = array ('From' => $from,
  'To' => $to,
  'Subject' => $subject);
$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>");
}

这种方法很好用，但我想使用我学到的方法将多个地址传递给标题，让最终用户只在 To：标题中看到他们的地址。我没有使用SMTP here。

这是我试图做的事情。允许SMTP服务器安全地发送邮件。

    <?php

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

    require_once "Mail.php";
    /*
       Gathers the number of rows within the database. Used for the loop that displays the entire list in the BCC. 
    */


     $host = "smtp.sendgrid.net";
     $port = "587";
     $username = "Account_Username";
     $password = "Account_Password";

      mysql_connect("MYSQL_HOST", "Username", "Password") or die(mysql_error()) ; 
      mysql_select_db("Database") or die(mysql_error()) ; 
      // 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 = $sub;

        // 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: test@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>
    <p>Test Message</p>
    </body></html>
    ';
        // Imploding the headers.
        $imploded_headers = implode("\r\n", $headers);

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

    $mail = $smtp->send($to, $subject, $message, $imploded_headers);

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

      }
    ?>

从运行脚本开始，我发现必须创建头字符串而不是数组。我尝试过并仍然收到相同的错误消息。

如何通过SMTP传递邮件，我该怎么做？

更新

我设法让它发送消息，虽然它是空的。出于某种原因，文件会附加到邮件中。该文件显示为＆＃34; noname＆＃34;大小为1.4KB。

<?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>");
}
?>

我排除了$imploded_headers = implode("\r\n", $headers);，因为这最初给了我错误＆＃34; $ header需要是数组＆＃34;。有什么想法吗？
