如何从 php 中的值数组中对特定字符串进行排序? [英] how to sort particular strings from an array of values in php?

问题描述

$array = array("2011-September_38","2011-June_4","2010-November_9","2011-November_29","2010-December_19");

我想对这个数组字符串进行如下排序，它应该先对年份进行排序，然后再对月份进行排序，

i want to sort this array strings as following, it should sort the year first, then it should sort the month,

期望的输出

Array ( [0] => 2010-Marh_19 
        [1] => 2010-November_9 
        [2] => 2011-June_4 
        [3] => 2011-September_38
        [4] => 2011-November_29 )

我尝试过一些东西，有人可以将我的函数绑定到排序年然后月 http://codepad.org/skEiUkTC

I've tried something, could anyone bind my function to sort year then month http://codepad.org/skEiUkTC

推荐答案

试试这个代码:

<?php
$array = array("2011-September_38","2011-June_4","2010-November_9","2011-November_29","2010-December_19");
function monthCompare($a, $b) {
   $da = strtotime(strstr($a, '_', true));
   $db = strtotime(strstr($b, '_', true));
   return $da > $db;
}
usort($array, "monthCompare");
print_r($array);
?>

输出

Array
(
    [0] => 2010-November_9
    [1] => 2010-December_19
    [2] => 2011-June_4
    [3] => 2011-September_38
    [4] => 2011-November_29
)
