示例代码,有些变量需要上下文环境:

$m = new Mail();
$m->setToaddr($this->temp['receipt_address']);
$m->setTopic($this->temp['mail_title']);
$m->setContent($this->temp['mail_content']);
$m->setFromaddr($_SESSION['user']['name'].' <'.$_SESSION['user']['name'].'@'.SystemDomain.'>');
$m->setDomain('@'.SystemDomain);
$m->setCc($this->temp['cc_address']);
$m->setAttach(PATH.'/temp/'.$this->temp['attachment_file']);
$m->send();
