我想每次用in_subject更改id_question.
foreach ($questions_array as $key => $row){
$subject_sort[$key] = $row['id_subject'];
$question_pattern_sort[$key] = $row['id_question_pattern'];
}
array_multisort($question_pattern_sort, SORT_ASC, $subject_sort, SORT_ASC, $questions_array);
推荐答案
如果我正确理解了您的问题，您可以做的是遍历数组并为数组的每个元素设置id_question = id_subject.
If I understand your question correctly, what you can do is loop through your array and set id_question = id_subject for each element of the array.
像这样:
foreach($questions_array['questions'] as $key=>$value){
$questions_array['questions'][$key]['id_question'] = $questions_array['questions'][$key]['id_subject'];
}
