致命错误:不能使用 stdClass 类型的对象作为数组 [英] Fatal error: Cannot use object of type stdClass as array in

问题描述

我收到错误:

第 183 行致命错误:无法使用 stdClass 类型的对象作为数组"

"Fatal error: Cannot use object of type stdClass as array in" on line 183

来自此代码:

$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
}

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?

Anyone know what's wrong with the above code? Or what this error means?

推荐答案

CodeIgniter 将结果行作为对象而不是数组返回.来自用户指南:

CodeIgniter returns result rows as objects, not arrays. From the user guide:

此函数以对象数组或失败时空数组的形式返回查询结果.

result()

---

This function returns the query result as an array of objects, or an empty array on failure.

您必须使用以下符号访问字段:

You'll have to access the fields using the following notation:

foreach ($getvidids->result() as $row) {
    $vidid = $row->videoid;
}
