我目前在向php中的多个用户发送邮件时遇到问题，我能够一次发送给一个用户，但邮件功能只将邮件发送给第一个用户而不发送邮件到第二个用户在$to变量中用逗号分隔的一个。
这是我的代码：
<?php
$reg = @$_POST['reg'];
if($reg) {
$to = "mail1@mail.com,mail2@mail.com";
$from = "hootpile@hootpile.com";
$subject = 'Hi VITian !';
$message = '<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Hi VITian.</title></head><body style="margin:0px; font-family:Tahoma, Geneva, sans-serif;"><center>

答案 0 :(得分：1)
使用多次mail（）函数：
$to = "hootpile@gmail.com, hootpile2@gmail.com";
foreach(explode(',', $to) as $mail) {
mail(trim($mail), $subject, $message, $headers);
}
这将为每个用户发送一封电子邮件。
