php mail function: Sending mails to BCC only
提问by Volatil3
the first param of php mail function is TO. Is there anyway to skip this parameter and use only CC/BCC to send bulk mails?
php邮件函数的第一个参数是TO。无论如何要跳过此参数并仅使用 CC/BCC 发送批量邮件？
Thanks
谢谢

An email message does not require a Toheader field. So you could pass nullor a blank string for the toparameter, set up your own header containing the BCCheader field and provide it with the fourth parameter additional_headersof mail:
一个电子邮件不需要为报头字段。所以，你可以通过null或为空字符串到参数，设置一个包含自己的头BCC报头字段，并为它提供了第四个参数additional_headers的mail：
$headerFields = array(
'BCC: [email protected], [email protected], [email protected]'
);
mail(null, $subject, $message, implode("\r\n", $headerFields));

You can specify fourth headers parameter for that like this:
您可以像这样指定第四个 headers 参数：
$xheaders = "";
$xheaders .= "From: <$from>\n";
$xheaders .= "X-Sender: <$from>\n";
$xheaders .= "X-Mailer: PHP\n"; // mailer
$xheaders .= "X-Priority: 1\n"; //1 Urgent Message, 3 Normal
$xheaders .= "Content-Type:text/html; charset=\"iso-8859-1\"\n";
$xheaders .= "Bcc:[email protected]"\n";
$xheaders .= "Cc:[email protected]\n";
//.......
mail($to, $subject, $msg, $xheaders);
In the $tofield you can specify your email or whatever you like.
在该$to字段中，您可以指定您的电子邮件或任何您喜欢的内容。
Notethat you can also specify multiple email addresses by separating them with a comma although I am not sure about exact number of email you can specify this way.
请注意，您还可以通过用逗号分隔多个电子邮件地址来指定多个电子邮件地址，尽管我不确定您可以通过这种方式指定的确切电子邮件数量。

You can put your own email address, or another dummy, in the Toheader, and put all the recipient addresses in Bcc.
您可以将自己的电子邮件地址或其他虚拟地址To放在标题中，并将所有收件人地址放在Bcc.
