php - echo 输出sql JOIN?

Question

如何echo输出以下查询？

我在 MySQL 数据库中的表:

$query = $this->db->query('SELECT geo.order FROM Store_Information si JOIN Geography AS geo ON geo.id = si.id WHERE si.name LIKE "%' . $find1 . '%"');

我的尝试不起作用:

if ($query->num_rows() > 0){
   foreach($query as $val) {
      $query_out = $query->row();
      echo $query_out->order . '<br>';
   }
}
else {
    echo '0';
}

我该怎么办？

您需要在 foreach 循环中添加 ->result():

// from the docs
$query = $this->db->query("YOUR QUERY");

foreach ($query->result() as $row)
{
    echo $row->title;
    echo $row->name;
    echo $row->body;
}
