PHP 将邮件发送给多个收件人而不共享电子邮件地址

Question

我正在尝试使用 PHP 向多个收件人发送电子邮件。我的代码是这样的

<?php
foreach($subscribers as $subscriber){ 
$email[] = $subscriber['email'];
}
$emails = implode(',', $email);
$email_from = "email@example.com";
$subject = "My Subject";
    $full_name = 'Example Sender';
    $from_mail = $full_name.'<'.$email_from.'>';
$email_text = file_get_contents('email.html');
$headers .= 'From: ' . $from_mail . "\r\n".
           "MIME-Version: 1.0" . "\r\n" . 
           "Content-type: text/html; charset=UTF-8" . "\r\n";
mail($emails, $subject, $email_text, $headers);
?>

我能够正确发送电子邮件。但它会在邮箱中显示其他电子邮件地址，我不想彼此共享电子邮件地址。请帮助我该怎么做。我尝试像这样在 for each 循环中发送电子邮件

<?php
    foreach($subscribers as $subscriber){ 
    $email = $subscriber['email'];
    $email_from = "email@example.com";
    $subject = "My Subject";
    $full_name = 'Example Sender';
    $from_mail = $full_name.'<'.$email_from.'>';
    $email_text = file_get_contents('email.html');
    $headers .= 'From: ' . $from_mail . "\r\n".
               "MIME-Version: 1.0" . "\r\n" . 
               "Content-type: text/html; charset=UTF-8" . "\r\n";
    mail($email, $subject, $email_text, $headers);
    }
?>

但它只向循环内的第一个电子邮件地址发送电子邮件。请帮忙。

您可以在$email 字段中添加一个空字符串，并使用密件抄送标头添加邮件地址。密件抄送确保收件人看不到其他电子邮件地址。

$headers .= "Bcc:email@example.com" . PHP_EOL;
