php - 将天数添加到日期

Question

我想在当前日期加上天数:我正在使用以下代码:

$i=30;
echo $date = strtotime(date("Y-m-d", strtotime($date)) . " +".$i."days");

但我得到的不是正确的日期，而是:2592000

请提出建议。

Answer 1

这应该是

echo date('Y-m-d', strtotime("+30 days"));

strtotime

expects to be given a string containing a US English date format and will try to parse that format into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 UTC), relative to the timestamp given in now, or the current time if now is not supplied.

而日期

Returns a string formatted according to the given format string using the given integer timestamp or the current time if no timestamp is given.
