Get date in php in 2 weeks
提问by anonymous123
$addhr = time() + (1 * 13 * 60 * 60);
$curDateTimeMil= date("Y-m-d G:i:s",$addhr);
echo $curDateTimeMil;
This will echo 2010-08-27 16:21:31.
这将回声2010-08-27 16:21:31。
How can I get the date after 2 weeks? (sept 10)
我怎样才能在 2 周后获得日期？（9 月 10 日）
回答by jensgram
$dateInTwoWeeks = strtotime('+2 weeks');
See strtotime().
Update #1: Yes, this is the lazy way to do it. However, I do believe that the possiblenegative performance impact is countered by the positive effect on readability / understanding of the code. Should performance be an issue, one could switch to native (integer-based) time manipulation (and add comments).
更新 #1：是的，这是一种懒惰的方法。但是，我确实相信可能的负面性能影响会被对代码可读性/理解的积极影响所抵消。如果性能是一个问题，可以切换到本机（基于整数）时间操作（并添加注释）。
Update #2: The optional second argument is the reference date. E.g.:
更新 #2：可选的第二个参数是参考日期。例如：
strtotime('+2 weeks', mktime(0, 0, 0, 2, 8, 1984)); // 8th Feb. 1984 + 2 weeks

You can specify the starting time (from where to calculate) using mktime().
您可以使用 指定开始时间（从哪里计算）mktime()。
Example: Two week after September 10, 2010 (i.e. +14 days):
示例：2010 年 9 月 10 日之后的两周（即 +14 天）：
$date = date("Y-m-d", mktime(0, 0, 0, 9, 10 + 14, 2010);
To get just the DATE (not time) of two weeks later (+14 days) from today:
从今天起仅获取两周后（+14 天）的 DATE（而非时间）：
$date = date("Y-m-d", mktime(0, 0, 0, date("m"), date("d")+14, date("Y")));
And this gives with TIME of two weeks later (+14 days) from now:
这是从现在起两周后（+14 天）的 TIME：
$date = date("Y-m-d G:i:s", mktime(date("G"), date("i"), date("s"), date("m"), date("d")+14, date("Y")));

You could simply add the number seconds of two weeks:
您可以简单地添加两周的秒数：
2 weeks = 2 · 7 days = 14 days
= 14 · 24 hours = 336 hours
= 336 · 60 minutes = 20160 minutes
= 20160 · 60 seconds = 1209600 seconds
So:
所以：
$curDateTimeMil += 1209600;
// or
$curDateTimeMil += 2 * 7 * 24 * 60 * 60;
