如何用年份和自定义字符串对数组进行排序? [英] How to sort an array with an year and custom string?

问题描述

我有一个像这样的数组

Q1 2017
Q3 2017
Q3 2012
Q4 2015
Q4 2017
Q2 2017

Q =一年的一季

我想像下面这样对这个数组进行排序

I want to sort this array like the following

Q2 2012
Q4 2015
Q1 2017
Q2 2017
Q3 2017
Q4 2017

排序按年份进行，但每年按季度进行.是否有可能?如果是，那怎么办?

The sorting is on year but in each year it is on quarter. Is it possible? If yes then how?

 );
$new = array();
foreach($arr as $subarr){
   $new[$subarr[1]][] = $subarr[0];
   sort($new[$subarr[1]]);
}
ksort($new);
$finalarr = array();
foreach($new as $key => $val){

$new = array();
foreach($arr as $key=>$subarr){
   $tempArr =  explode(' ', $key);   
   $new[$tempArr[1]][$tempArr[0]] = $subarr;
   asort($new[$tempArr[1]]);
}

ksort($new);
$secondarr = array();
foreach($new as $k=>$v){
    ksort($v);
    $secondarr[$k] = $v;
}

foreach($secondarr as $key => $val){
    foreach($val as $k=>$v){
        $newkey = $k.' '.$key;
        $finalarr[$newkey] = $v;
    }
}

 echo "<pre>"; print_r($finalarr);
