我正在将数据从控制器发送到模型var_dump
$score
如图所示
Array
(
[assessment_score] => Array
(
[0] => Array
(
)
[1] => Array
(
[0] => stdClass Object
(
[id] => 3
[score] => 4
[assessment_id] => 1
[assessor_id] => 24
[level_test] => 2
)
[1] => stdClass Object
(
[id] => 4
[score] => 5
[assessment_id] => 1
[assessor_id] => 24
[level_test] => 3
)
)
[2] => Array
(
)
[3] => Array
(
)
)
[assessment_msg] => Array
(
[0] => Array
(
)
[1] => Array
(
[0] => stdClass Object
(
[id] => 1
[user_id] => 21
[start_time] => 2012-05-20 20:45:30
[status] => 0
[end_time] => 2012-05-21 20:45:30
[assessor1] => 25
[assessor2] => 24
[assessor3] => 0
[gd_msg] =>
[gd_pf] =>
[csgd_msg] =>
[csgd_pf] =>
[pi_msg] =>
[pi_pf] =>
[wr_msg] =>
[wr_pf] =>
)
)
[2] => Array
(
[0] => stdClass Object
(
[id] => 4
[user_id] => 28
[start_time] => 2012-05-23 13:38:32
[status] => 0
[end_time] => 2012-05-24 13:38:32
[assessor1] => 23
[assessor2] => 0
[assessor3] => 0
[gd_msg] =>
[gd_pf] =>
[csgd_msg] =>
[csgd_pf] =>

)
[3] => Array
(
[0] => stdClass Object
(
[id] => 3
[user_id] => 22
[start_time] => 2012-05-14 14:00:41
[status] => 0

[assessor3] => 0
[gd_msg] =>

[csgd_msg] =>
[csgd_pf] =>
[pi_msg] =>
[pi_pf] =>
[wr_msg] =>
[wr_pf] =>
)
)
)
)
但是当我评估它时
$user_score = array();
if (count($score['assessment_score'][$i]) > 0) {
foreach ($score['assessment_score'][$i] as $score) {
$user_score[$score->level_test] = $score->score;
}
}
引发错误
( ! ) Fatal error: Cannot use object of type stdClass as array
in C:'xampp'htdocs'ci'application'views'users'users_score_list.php
到行
if (count($score['assessment_score'][$i]) > 0) {
怎么解决？如何避免致命错误，因为它会破坏我的进一步处理。下面是var_export
array (
'assessment_score' =>
array (
0 =>
array (
),
1 =>
array (
0 =>
stdClass::__set_state(array(
'id' => '3',

不要在 foreach() 循环中两次使用相同的变量名称 （ $score ）！
溶液：
if (count($score['assessment_score'][$i]) > 0) {
foreach ($score['assessment_score'][$i] as $data) { // $data instead of $score
$user_score[$data->level_test] = $data->score; // $data instead of $score
}
}
似乎score["assessment_score"][$i]是一个数组因此，要访问 1° 对象，您需要使用 S core["assessment_score"][1][0]
