        [5] => Array
            (
                [ExamMonth] => Array

                [Subject] => Array
                    (
                        [subject_name] => Hindi

            )

        [6] => Array
            (
                [ExamMonth] => Array

                [ExamType] => Array
                    (
                        [exam_type] => Examinations
                    )

                [Month] => Array
                    (
                        [class_subject_id] => 0
                        [marks_obtained] => 124

                    )

                [Subject] => Array
                    (
                        [subject_name] => Geography
                    )

            )

    )

但我需要像

这样的数组

[May]=>Array {
             [0]=>Array (
 [ExamType] => Array
                    (
                        [exam_type] => Grades
                    )

                [Month] => Array
                    (
                        [class_subject_id] => 0
                        [marks_obtained] => 0
                        [grade] => 
                    )

                [Subject] => Array
                    (
                        [subject_name] => Punjabi
                    )
    )
So on 
[September ]=>Array

}

我不知道该怎么做。谁能告诉我怎么做？

提前致谢

Answer 1

这样的事情可以解决问题：

foreach ($yourArray as $exam) {
  $newArray[$exam['ExamMonth']['month']][] = array(
    'ExamType' => $exam['ExamType'],
    // etc.
  );
}

Answer 2

这样的事情应该可以工作：

$newArr = array();
foreach($months as $month) {
  $newArr[$month['ExamMonth']['name']] = $month;
  unset($newArr[$month['ExamMonth']]);
}

Answer 3

主要的错误位是括号。数组在 () 中定义。另外，我希望它是伪代码，因为它不是一个完整的有效语句。这将是一个完整的实例：

$School = array
    (
    [May]=>Array
         (
         [0]=>Array
             (
             [ExamType] => Array  ( [exam_type] => Grades )
             [Month] => Array (
                              [class_subject_id] => 0
                              [marks_obtained] => 0
                              [grade] => 
                              )
             [Subject] => Array ( [subject_name] => Punjabi )
             )
         [1]=>Array
             (
             [ExamType] => Array  ( [exam_type] => Grades )
             [Month] => Array (
                              [class_subject_id] => 0
                              [marks_obtained] => 0
                              [grade] => 
                              )
             [Subject] => Array ( [subject_name] => Punjabi2 )
             )
         )
    [Juny]=>Array
         (
         [2]=>Array
             (
             [ExamType] => Array  ( [exam_type] => Grades )
             [Month] => Array (
                              [class_subject_id] => 0
                              [marks_obtained] => 0
                              [grade] => 
                              )
             [Subject] => Array ( [subject_name] => Punjabi )
             )
         )
    )
