我已經搜索了有關此問題的類似重復項，但沒有任何效果。
這是我自動發送電子郵件的代碼。我已經啟動了資料和方法如下，
<?php
$reportdate=date('Y-m-d',strtotime("-1 days"));
$To = '[email protected]';
$Cc = '[email protected]';
$Subject = 'Data as at '.$reportdate;
//this functin processes the server return codes and generates errors if needed
function server_parse($socket, $expected_response)
{
$server_response = '';
while (substr($server_response, 3, 1) != ' ')
{
if (!($server_response = fgets($socket, 256)))
echo 'Couldn\'t get mail server response codes. Please contact the forum administrator.', __FILE__, __LINE__;
//exit;
}
if (!(substr($server_response, 0, 3) == $expected_response))
echo 'Unable to send e-mail. Please contact the forum administrator with the following error message reported by the SMTP server: "'.$server_response.'"', __FILE__, __LINE__;
//exit;
}
//
// This function was originally a part of the phpBB Group forum software phpBB2 (http://www.phpbb.com).
// They deserve all the credit for writing it. I made small modifications for it to suit PunBB and it's coding standards.

這作業正常。但我沒有收到任何抄送收件人的電子郵件。有人可以幫助我嗎？我也嘗試過更換標題。但是，當我將所有抄送收件人復制到 $TO 時，這也可以正常作業。
uj5u.com熱心網友回復：
作為記錄，我不是 SMTP 協議方面的專家，但是您似乎缺少實際發送抄送收件人的機會。
嘗試像這樣添加另一個 foreach 回圈：
foreach ($recipients as $email)
{
fwrite($socket, 'RCPT TO: <'.$email.'>'."\r\n");
server_parse($socket, '250');
}
foreach ($recipientscc as $email)
{
fwrite($socket, 'RCPT TO: <'.$email.'>'."\r\n");
server_parse($socket, '250');
}
根據對此事的快速谷歌搜索，“To”、“CC”和“BCC”之間的區別實際上只是在標題中，就像主題一樣。
