.jpg等其他格式的文件可以下载xlsx格式 每次只是提供错误消息失败时无法下载 下载xslx类型格式。为该错误提供任何解决方案。
这是我的代码
$date1 = new DateTime("2017-05-14");
$date2 = new DateTime("2017-06-14");
$interval = $date1->diff($date2);
$week = floor($date1->diff($date2)->days/7);
echo $week;
if($week > 4)
{
echo $interval->m.' '.($interval->m > 1 ? 'months' : 'month');
}
