如何在PHP中获取15天/ 1个月后的日期？

使用 strtotime。

$newDate = strtotime('+15 days',$date)

$newDate现在是$date后的15天。$date是unix时间。

试试这个

$date = date("Y-m-d");// current date

$date = strtotime(date("Y-m-d", strtotime($date)) . " +1 day");
$date = strtotime(date("Y-m-d", strtotime($date)) . " +1 week");
$date = strtotime(date("Y-m-d", strtotime($date)) . " +2 week");
$date = strtotime(date("Y-m-d", strtotime($date)) . " +1 month");
$date = strtotime(date("Y-m-d", strtotime($date)) . " +30 days");
