在PHP中以MySQL Date格式设置的日期中增加天数

Question

有没有一种方法可以将一定天数添加到格式为2010-10-17的日期中，而无需像在php中使用strtotime函数那样将其转换为unix时间戳？

Answer 1

You can play around with the DateTime library .

So, based on your description, something like the following should do the trick:

$date = new DateTime('2010-10-17');
$date->add(new DateInterval('P10D')); //adding ten days
echo $date->format('Y-m-d') . "\n";

Outputs: 2010-10-27

Although I'm curious as to why you do not want to work with timestamps? As they're the most flexible choice here.
