MVC框架中可捕获的致命错误

我正在尝试为我的PHP脚本设置一个简单的MVC框架。 模特('会议'):

  public function getConferenceLogs($pin){

    $stmt_conferences = $this->db->prepare(
      'SELECT
      date_created,
      timediff(date_completed, date_created) AS duration,
      RecordURL,
      conference_sid
      FROM
      conference
      WHERE
      pin=:pin');
    $stmt_conferences->bindParam(':pin', $pin);
    $stmt_conferences->execute();

    $count =  $stmt_conferences->rowCount();
    if ($count !== 0) {
      $row = $stmt_conferences->fetch();
      return $row;
    }

    return false;
  }

控制器:

function conference_history() 

{        
    Auth::handleLogin();

    $this->loadModel('conference');
    $row = $this->model->getConferenceLogs(Session::get('user_pin'));
    $this->view->row = $row;
    $participant = $this->model->getParticipantLogs(Session::get('user_pin'));
    $this->view->participant = $participant;

    $this->view->render('account/conference_history');
}

查看:

<?php 

 var_dump($this->row);    

?>

我知道模型中的这个查询应该返回至少7条记录,当在传统格式(https://stackoverflow.com/a/20275597/2429989 的MVC框架外执行时p>

但是,var_dump($ this-&gt;行)会产生以下结果:

object(stdClass)[5]
  public 'date_created' => string '2013-10-29 19:20:37' (length=19)
  public 'duration' => string '00:03:42' (length=8)
  public 'RecordURL' => string '' (length=0)
  public 'conference_sid' => string '1c540158-40cf-11e3-b4cc-81e296145de2' (length=36)

我认为这意味着只有一条记录?我想显示所有7条记录;我设置了错误的查询还是我的echo语句?我想显示每个属性的所有7条记录(例如print $ this-&gt; row-&gt; date_created)。

答案 0 :(得分:2)

查看你的var_dump,$ this-&gt;行只是一个对象,它不能被转换为字符串。因此,您需要访问公共属性:

<?php
print $this->row->date_created;
...//repeat as needed
?>

或者,如果某种集合中有多个行对象

<?php
foreach($this->row_collection->row as $row){
    print $row->date_created;
...//blah blah blah
}
