PHP数组排序 [英] php array sorting

问题描述

我有一个php数组

Array
(
[0] => Array
    (
        [MF_B302] => Array
            (
                [FAILURE_DATE] => 2010-02-01 00:00:00
            )

        [0] => Array
            (
                [claimnum] => 1
            )
    )

[1] => Array
    (
        [MF_B302] => Array
            (
                [FAILURE_DATE] => 2009-08-10 00:00:00
            )

        [0] => Array
            (
                [claimnum] => 2
            )
    )
)

我需要根据[FAILURE_DATE]进行排序，是否有人可以执行此操作？

i need to sort that according to [FAILURE_DATE], does any one have a function to do this?

谢谢...

推荐答案

这应该有助于您熟悉数组排序的基础知识在PHP中

This should help you brush up on the basics of array sorting in PHP

类似的东西会排序但是，您的问题是：

Something like this would sort your problem however:

usort($array, "cmp");

function cmp($a, $b){ 
    return strcmp($b['FAILURE_DATE'], $a['FAILURE_DATE']); 
}
