【PHP】mail()亂碼及相關用法

mail()使用Bcc 及cc 用法
ex:
$headers = "From: me@mydomain.com";
$headers .= "\r\nCc: he@$hisdomain.com";
$headers .= "\r\nBcc: her@$herdomain\r\n\r\n";

============================================
使用mb_send_mail代替mail函數
ex:
/* Set internal character encoding to UTF-8 */
mb_internal_encoding("UTF-8");

$from = "From: ". $_POST['email'];
$from.="\nContent-Type:text/html;charset=utf-8";
$subject = CURRENT_DATE ." 訂購單";
$body // 內文 html語法
mb_send_mail($to, $subject, $body, $from);

=======================================

$subject = "客戶 ".$name." 要求代客尋車";
$subject = "=?UTF-8?B?" . base64_encode($subject) . "?=";
