在PHP中轉換數組類型

Question

請幫助將數組從一種形式轉換為另一種形式

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_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] => 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_pse_boys_36m_72m] => 5020964 
    [total_pse_all_girls_36m_72m] => 5051785 
    [total_pregnanting] => 2815773

    )

我要這個

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

。 。 。 。 。 。 。 。

Answer 1

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（大數組，包含所有其他數組），遍歷每個內部數組並將值存儲在正確的位置。

Answer 2

您可以使用array_column函數。 但是請注意，此功能僅適用於PHP> = 5.5.0。 嘗試這個：

//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);
}

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
        )

)
