如何選擇特定的JSON值來創建一個字符串？

Question

我有以下JSON輸出：

"data" => "[ 
       {"month":2,"total_payments":"720.00"}, 
       {"month":3,"total_payments":"500.00"} 
      ]" 

我奮力的語法選擇一個特定的值，以創建一個字符串。例如，我希望能夠輸出：

$month = ["2", "3"] 
$total_payments = ["720", "500"] 

到目前爲止，我有這樣的代碼，但不工作。

<?php echo $data->month?>

你必須遍歷陣列，並且獲取你想要的信息。例如：

$months = array(); 
$total_payments = array(); 
foreach($datas['data'] as $data) { 
    $months[] = $data->month; 
    $total_payments[] = $data->total_payments; 
}
