问题描述

row_array()和result_array()有什么区别?

它们如何在视图页面上显示?

How would they be displayed on a view page?

if ($variable) {
    return $result->row_array();
} else {
    return $result->result_array();
}

推荐答案

来自文档 ，row_array返回一个结果，result_array返回多个结果(通常用于循环).

From the documentation, row_array returns a single result and result_array returns multiple results (usually for use in a loop).

文档中的示例:

结果数组:

$query = $this->db->query("YOUR QUERY");

foreach ($query->result_array() as $row)
{
   echo $row['title'];
   echo $row['name'];
   echo $row['body'];
}

行数组:

$query = $this->db->query("YOUR QUERY");

if ($query->num_rows() > 0)
{
   $row = $query->row_array(); 

   echo $row['title'];
   echo $row['name'];
   echo $row['body'];
}
