我有一个关于电子邮件模板中循环的问题。我当前的电子邮件库传递了一个数据数组和一个要搜索和替换的模板（.html）。如果我只需要替换任何封装在方括号[variable]中的元素，这就很好了。然而，我的库无法处理数据数组（循环），我需要一个比下面的丑陋方法更优雅的解决方案
干杯。
电子邮件库

未定义模板的丑陋方法
注意：很抱歉这里的格式不正确
我必须在运行中传递一个模板，这样我就可以用数据运行foreach循环，而不是使用预先制作的模板

编辑：答案感谢landons，
if ($order->update_attributes($update_order)) {
$output = $this->load->view('orders/email', array(
'data' => $somedata
), true);
if (Mailer::sendIt($output, '', $user->email, 'Purchase Confirmation: #' . $order->order_sku . '', false)) {
return true;
}
}
您是否考虑过简单地将数据传递到视图（并返回内容，而不是显示内容）？
