php - php计算过去每一天的成本

Question

  $1date =$row['Date1'];
     $2date = $row['Date2'];
       $datediff = $1date - $2date;
echo $datediff;

我想计算之间的天数并将结果放入表格中（过去每天 10 美元）

Answer 1

您可以在 MySQL 中执行此操作，然后将其转换为变量。进行初始呼叫

SELECT TIMESTAMPDIFF('Date1','Date2'); 

Answer 2

// convert to unix timestamp
$1date = strtotime($row['Date1']);
$2date = strtotime($row['Date2']);

// 86400 seconds in a day
// floor to round down, change to ceil to round up
$datediff = floor(($1date - $2date) / 86400);

$cost = $days * 10;

Answer 3

尝试：

$days = date_diff(date_create($row['Date1']), date_create($row['Date2']))->format('%a');
$cost = $days * 10;
