php发邮件给多个人

        $to = '[e-mail],[e-mail]';        $subject = 'count of upd files less than time span';        $message = AFFILIATE_NAME."_".AFFID.'=> lost upd files: '.implode(',',$lostUpdWithDatArr);        $headers = "MIME-Version: 1.0" . "\r\n";        $headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";        $headers .= 'From: <[e-mail]>'. "\r\n";        $result = mail($to, $subject, $message, $headers);

当发邮件给多个人的时候，用逗号隔开即可
