Use strtotime.
使用 strtotime。
$newDate = strtotime('+15 days',$date)
$newDate will now be 15 days after $date. $date is unix time.
$newDate 现在将是 $date 之后的 15 天。$date 是 unix 时间。

try this
尝试这个
$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");

Since PHP 5.2.0 the DateTimebuild in class is available
自 PHP 5.2.0 起，DateTime内置类可用
$date = new DateTime($postedDate);
$date->modify('+1 day');
echo $date->format('Y-m-d');

$date=strtotime(date('Y-m-d')); // if today :2013-05-23
$newDate = date('Y-m-d',strtotime('+15 days',$date));
echo $newDate; //after15 days :2013-06-07
$newDate = date('Y-m-d',strtotime('+1 month',$date));
echo $newDate; // after 1 month :2013-06-23

What's the input format anyway?
无论如何输入格式是什么？
1) If your date is, say, array of year, month and day, then you can mktime (0, 0, 0, $month, $day + 15, $year) or mktime (0, 0, 0, $month + 1, $day, $year). Note that mktime is a smart function, that will handle out-of-bounds values properly, so mktime (0, 0, 0, 13, 33, 2008) (which is month 13, day 33 of 2008) will return timestamp for February, 2, 2009.
1) 如果您的日期是年、月和日的数组，那么您可以 mktime (0, 0, 0, $month, $day + 15, $year) 或 mktime (0, 0, 0, $month + 1, $day, $year)。请注意，mktime 是一个智能函数，它将正确处理越界值，因此 mktime (0, 0, 0, 13, 33, 2008)（即 2008 年的第 13 个月，第 33 天）将返回二月的时间戳, 2, 2009。
2) If your date is a timestamp, then you just add, like, 15*SECONDS_IN_A_DAY, and then output that with date (/* any format */, $postedDate). If you need to add one month 30 days won't of course always work right, so you can first convert timestamp to month, day and year (with date () function) and then use (1).
2) 如果您的日期是时间戳，那么您只需添加 15*SECONDS_IN_A_DAY，然后将其与日期一起输出（/* 任何格式 */，$postedDate）。如果您需要添加一个月 30 天当然不会总是正常工作，因此您可以先将时间戳转换为月、日和年（使用 date() 函数），然后使用（1）。
3) If your date is a string, you first parse it, for example, with strtotime (), then do whatevee you like.
3）如果你的日期是字符串，你先解析它，比如用strtotime()，然后做你喜欢的。
