如何使用领域之一，在排序PHP数组 [英] How to sort array in PHP using one of the field

问题描述

我想在PHP中的数组进行排序。请参阅我的数组：

I'm trying to sort the array in PHP. Please see my array:

Array
(
    [0] => Array
        (
            [id] => 8
            [date_start_month_name] => January
            [approved] => Accepted: yes
        )

    [1] => Array
        (
            [id] => 3
            [date_start_month_name] => January
            [approved] => Accepted: yes
        )

    [2] => Array
        (
            [id] => 2
            [date_start_month_name] => March
            [approved] => Accepted: yes
        )

    [3] => Array
        (
            [id] => 5
            [date_start_month_name] => April
            [approved] => Accepted: yes
        )

)

我想用一个月的名称，例如数组进行排序：月并得到这样的：

Array
(
    [0] => Array
        (
            [id] => 8
            [date_start_month_name] => January
            [approved] => Accepted: yes
        )

    [1] => Array
        (
            [id] => 3
            [date_start_month_name] => January
            [approved] => Accepted: yes
        )
)

我怎样才能做到这一点？感谢您事先的任何帮助。最好的！

How can I do that? Thanks in advance for any help. Best!

推荐答案

使用 usort

usort($array, function($a, $b) {
    return $a['date_start_month_name'] > $b['date_start_month_name']
});
