如何选择特定的JSON值来创建一个字符串？

Question

我有以下JSON输出：

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

我奋力的语法选择一个特定的值，以创建一个字符串。例如，我希望能够输出：

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

到目前为止，我有这样的代码，但不工作。

<?php echo $data->month?>

你必须遍历阵列，并且获取你想要的信息。例如：

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