Fatal error: Cannot use object of type stdClass as array in
提问by kyle
I'm getting the error:
我收到错误：
"Fatal error: Cannot use object of type stdClass as array in" on line 183
第 183 行的“致命错误：无法使用 stdClass 类型的对象作为数组”
From this code:
从这个代码：
$getvidids = $ci->db->query(
"SELECT * FROM videogroupids " .
"WHERE videogroupid='$videogroup' AND used='0' LIMIT 10");
foreach ($getvidids->result() as $row){
$vidid = $row['videoid']; //This is line 183
}
Anyone know what's wrong with the above code? Or what this error means?
有人知道上面的代码有什么问题吗？或者这个错误是什么意思？

CodeIgniter returns result rows as objects, not arrays. From the user guide:
CodeIgniter 将结果行作为对象而不是数组返回。从用户指南：
result()
This function returns the query result as an array of objects, or an empty arrayon failure.
结果（）
此函数以对象数组或失败时的空数组形式返回查询结果。
You'll have to access the fields using the following notation:
您必须使用以下表示法访问字段：
foreach ($getvidids->result() as $row) {
$vidid = $row->videoid;
}

if you really want an array instead you can use:
如果你真的想要一个数组，你可以使用：
$getvidids->result_array()
which would return the same information as an associative array.
这将返回与关联数组相同的信息。

Controller(Example: User.php)
控制器（例如：User.php）
<?php
defined('BASEPATH') or exit('No direct script access allowed');
class Users extends CI_controller
{
// Table
protected $table = 'users';
function index()
{
$data['users'] = $this->model->ra_object($this->table);
$this->load->view('users_list', $data);
}
}
View(Example: users_list.php)
查看（例如：users_list.php）
<table>
<thead>
<tr>
<th>Name</th>
<th>Surname</th>
</tr>
</thead>
<tbody>
<?php foreach($users as $user) : ?>
<tr>
<td><?php echo $user->name; ?></td>
<td><?php echo $user->surname; ?></th>
</tr>
<?php endforeach; ?>
</tbody>
</table>
<!-- // User table -->

Sorry.Though it is a bit late but hope it would help others as well . Always use the stdClass object.e.g
对不起。虽然有点晚了，但希望它也能帮助其他人。始终使用 stdClass object.eg
$getvidids = $ci->db->query("SELECT * FROM videogroupids WHERE videogroupid='$videogroup' AND used='0' LIMIT 10");
foreach($getvidids->result() as $key=>$myids)
{
$vidid[$key] = $myids->videoid; // better methodology to retrieve and store multiple records in arrays in loop
}
