PHP mail() BCC - 仅显示 To: header 中的最终收件人地址
PHP mail() BCC - display only the end receivers address in To: header
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 运行 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header中，"To:"在列表的所有接收端都显示为空白。我理解并知道 header 不会显示，因为我在外发消息中只有密件抄送 header。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，尽管我收到了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，由 BBC 到列表并在 To:[= 中仅显示接收端电子邮件地址33=] header。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>");
}
?>
将\r\n添加到：
$headers .= "BCC: $contacts\r\n";
每个 header 必须换行。
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。
