如何将php关联数组排序为特定顺序? [英] How to sort a php associative array to a specific order?

问题描述

这是我要按特定顺序排序的数组

this is the array i like to sort in a particular order

$aData = Array
  (
    [break] => Array
        (
            [Indoor room] => 42
            [Gym Class] => 19
        )
    [finish] => Array
        (
            [Indoor room] => 42
            [Gym Class] => 19
        )

    [lunch] => Array
        (
            [Indoor room] => 7
        )

    [period1] => Array
        (
            [Indoor room] => 12
            [Gym Class] => 22
        )

    [period2] => Array
        (
            [Gym Class] => 14
            [Indoor room] => 25
        )

    [period3] => Array
        (
            [Gym Class] => 21
            [Indoor room] => 11
        )

    [period4] => Array
        (
            [Gym Class] => 22
            [Indoor room] => 20
        )

    [period5] => Array
        (
            [Gym Class] => 16
            [Indoor room] => 9
        )

)

但是我喜欢这个顺序:

break, period1, period2, lunch, period3, period5, period6, finish

为此，我正在尝试以下php代码

for this I am trying the following php code

$arraySort = [
  "break",  
  "period1", 
  "period2", 
  "period3", 
  "lunch",
  "period4",
  "period5", 
  "period6", 
  "finish" 
];

   foreach($aData as $period => $catsScore){
  echo 'test '.$period.'<br/>';  
  $periodItem = [$period];
  foreach($arraySort as $cat){
      echo 'new: '.$cat.'<br/>';
      $periodItem[] = $catsScore;
  }
  $output[] = $periodItem;
    }


print_r($output);

推荐答案

Easy- 只需使用 arraySort 作为assoc键并获取原始数组中对应的数组/值

Easy- Just use the arraySort as the assoc key and get the corresponding array / value from the original array,

<?php

$arraySort = [
  "break",  
  "period1", 
  "period2", 
  "period3", 
  "lunch",
  "period4",
  "period5", 
  "period6", 
  "finish" 
];

$final_array = [];

foreach($arraySort  as $arraySo){
  $final_array[$arraySo] = $aData[$arraySo];
}

print_r($final_array);
