public function getReply() {

$id =17;
$myreply = M('myreply');
$myreply_data = $myreply -> where("pid = 17") -> order("addtime desc") -> select();

var_dump($myreply_data[0]['email']);//值为afeng
$this->assign('myreply_data',$myreply_data);
$this->display('question');}

question.html
<div class="name_say"><b>{$myreply_data[0]['email']}
</b></div>
为什么页面没有显示{$myreply_data[0]['email']}的值为afeng
