如何將php關聯數組排序爲特定順序？

Question

這是我喜歡在一個特定的順序

$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 
     ) 

) 

排序的數組，但我喜歡它的順序是：

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

這個我想下面的PHP代碼

$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

Easy-只需使用arraySort作爲關鍵字，從原來的陣列得到相應的陣列/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

您可以使用array_combine用於此目的：

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

Answer 3

請正確有序陣列和值填充源陣列

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

Answer 4

另外，您可以使用一個實際排序功能：

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