php发邮件给多个人

        $to = '[email protected],[email protected]';
        $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: '. "\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
