根据php中数组中的值拆分数组[重复]

Question

您好，我想根据数组的值拆分数组。比如说我的数组是这样的

 Array
(
 [0] => Array
    (
        [id] => 1
        [amount] => 800
        [detail] => bus fare
        [student_id] => 16
        [class_id] => 1
        [bill_id] => 5a6c176b0b27a
        [total] => 1800
    )

[1] => Array
    (
        [id] => 2
        [amount] => 1000
        [detail] => tast
        [student_id] => 16
        [class_id] => 1
        [bill_id] => 5a6c176b0b27a
        [total] => 1800
    )

[2] => Array
    (
        [id] => 3
        [amount] => 5000
        [detail] => tution
        [student_id] => 16
        [class_id] => 1
        [bill_id] => 5a6d3a1d67feb
        [total] => 5150
    )

[3] => Array
    (
        [id] => 4
        [amount] => 150
        [detail] => busfare
        [student_id] => 16
        [class_id] => 1
        [bill_id] => 5a6d3a1d67feb
        [total] => 5150
    )

) 我想以 bill_id 为基础拆分数组。表示具有相同账单 ID 的数组必须在一个部分下。请帮助我实现这一目标。

这是通话组，请查看link

$bill_id = Arrays::groupBy($actual_array, Functions::extractField('bill_id'));

希望对你有所帮助。
