轉換數組類型在PHP

Question

請在陣列中的轉換幫助從一種形式到另一個我得到這個數組

Array ( 
    [mpr_last_month] => 376431 
    [mpr_month] => 03 
    [total_boys_all_6m_36m] => 5550225 
    [total_girls_all_6m_36m] => 5215529 
    [total_boys_all_36m_72m] => 4209639 
    [total_girls_all_36m_72m] => 4149613 
    [total_pse_boys_36m_72m] => 4442301 
    [total_pse_all_girls_36m_72m] => 4413446 
    [total_pregnanting] => 2209158) 



Array (
    [mpr_last_month] => 448216 
    [mpr_month] => 04 
    [total_boys_all_6m_36m] => 7153209 
    [total_girls_all_6m_36m] => 6798913 
    [total_boys_all_36m_72m] => 5175846 
    [total_girls_all_36m_72m] => 5105460 
    [total_pse_boys_36m_72m] => 5290617 
    [total_pse_all_girls_36m_72m] => 5263340 
    [total_pregnanting] => 2944612 
    ) 

Array ( 
    [mpr_last_month] => 448253 
    [mpr_month] => 05 
    [total_boys_all_6m_36m] => 11742417 
    [total_girls_all_6m_36m] => 6362815 
    [total_boys_all_36m_72m] => 4879252 
    [total_girls_all_36m_72m] => 4756805 
    [total_pse_boys_36m_72m] => 5344042 
    [total_pse_all_girls_36m_72m] => 5095155 
    [total_pregnanting] => 2852864 

    ) 

Array ( 
    [mpr_last_month] => 470848 
    [mpr_month] => 06 
    [total_boys_all_6m_36m] => 6552523 
    [total_girls_all_6m_36m] => 6217771 
    [total_boys_all_36m_72m] => 4613019 
    [total_girls_all_36m_72m] => 4551685 
    [total_pse_boys_36m_72m] => 5182666 
    [total_pse_all_girls_36m_72m] => 5165730 
    [total_pregnanting] => 2746293 
    ) 

Array ( 
    [mpr_last_month] => 465489 
    [mpr_month] => 07 
    [total_boys_all_6m_36m] => 6638749 
    [total_girls_all_6m_36m] => 6310676 
    [total_boys_all_36m_72m] => 4801665 
    [total_girls_all_36m_72m] => 4657764 
    [total_pse_boys_36m_72m] => 5020964 
    [total_pse_all_girls_36m_72m] => 5051785 
    [total_pregnanting] => 2815773 

    ) 

我想這

name: 'mpr_last_month', 
data: [43934, 52503, 57177, 69658, 97031, 119931, 137133, 154175,123,123,123,123]

Answer 1

您可以使用array_column函數。但請注意，該功能僅適用於PHP> = 5.5.0。試試這個：

//example data 
$array = [ 
    ['a' => 2, 'b'=>3, 'c'=>6], 
    ['a' => 12, 'b'=>13, 'c'=>16], 
    ['a' => 22, 'b'=>23, 'c'=>26], 
]; 


$result = []; 

//get indexes from first element of array 
$indexes = array_keys($array[0]); 

foreach($indexes as $index) { 
    $result[$index] = array_column($array, $index); 
} 

而且結果是：

Array 
(
    [a] => Array 
     (
      [0] => 2 
      [1] => 12 
      [2] => 22 
     ) 

    [b] => Array 
     (
      [0] => 3 
      [1] => 13 
      [2] => 23 
     ) 

    [c] => Array 
     (
      [0] => 6 
      [1] => 16 
      [2] => 26 
     ) 

) 

Answer 2

最簡單的方法是foreach循環。

$newData = []; 
foreach ($yourArray as $innerArray) { 
    foreach ($innerArray as $key => $value) { 
     $newData[$key][] = $value; 
    } 
} 

它循環遍歷第一個數組（包含所有其他數組），遍歷每個內部數組並將其存儲在正確位置。
