我正在从控制器向模型发送数据 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] =>
[pi_msg] =>
[pi_pf] =>
[wr_msg] =>
[wr_pf] =>
)
)
[3] => Array
(
[0] => stdClass Object
(
[id] => 3
[user_id] => 22
[start_time] => 2012-05-14 14:00:41
[status] => 0
[end_time] => 2012-05-17 14:00:41
[assessor1] => 25
[assessor2] => 0
[assessor3] => 0
[gd_msg] =>
[gd_pf] =>
[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] = $score->score;
}
}
抛出错误
( ! ) Fatal error: Cannot use object of type stdClass as array
in C:\xampp\htdocs\ci\application\views\users\users_score_list.php
到
行 if (count($score['assessment_score'][$i]) > 0) {
如何解决？ 如何避免致命错误，因为它打破了我的进一步处理。 下面一个是var_export

答案 0 :(得分：2)
请勿在{{1}}循环中使用相同的var名称（$score）两次！
解决方案：
foreach()答案 1 :(得分：0)
似乎score["assessment_score"][$i]是一个数组
所以要访问1°对象，你需要使用s core["assessment_score"][1][0]
