Question

这是我想按特定顺序排序的数组

$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
        )

)

但我喜欢这个顺序：

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

为此我尝试以下PHP代码

$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);

Answer 1

简单 - 只需使用arraySort作为关键字，并从原始数组中获取相应的数组/值，

<?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);

Answer 2

制作正确排序的数组并按源数组

的值填充它

$final_array = array_replace(array_fill_keys($arraySort, []), $aData);

demo

Answer 3

或者您可以使用实际排序功能：

uksort(
    $aData,
    function($a,$b)use($arraySort){
        return array_search($a, $arraySort) - array_search($b, $arraySort);
    }
);

Answer 4

您可以将array_combine用于此目的：

$arrary_sort = ["break", "period1"];
$final_array = array_combine($array_sort, $your_array_here);

如何将php关联数组排序到特定的顺序？
