How do I add 24 hours to a unix timestamp in php?
提问by zeckdude
I would like to add 24 hours to the timestamp for now. How do I find the unix timestamp number for 24 hours so I can add it to the timestamp for right now?
我现在想在时间戳中添加 24 小时。如何找到 24 小时的 Unix 时间戳编号，以便我现在可以将其添加到时间戳？
I also would like to know how to add 48 hours or multiple days to the current timestamp.
我还想知道如何将 48 小时或多天添加到当前时间戳。
How can I go best about doing this?
我怎样才能最好地做到这一点？

You probably want to add one day rather than 24 hours. Not all days have 24 hours due to (among other circumstances) daylight saving time:
您可能想要添加一天而不是 24 小时。由于（在其他情况下）夏令时，并非所有日子都有 24 小时：
strtotime('+1 day', $timestamp);

A Unix timestamp is simply the number of seconds since January the first 1970, so to add 24 hours to a Unix timestamp we just add the number of seconds in 24 hours. (24 * 60 *60)
Unix 时间戳只是自 1970 年 1 月以来的秒数，因此要向 Unix 时间戳添加 24 小时，我们只需添加 24 小时内的秒数。(24*60*60)
time() + 24*60*60;

Unix timestamp is in seconds, so simply add the corresponding number of seconds to the timestamp:
Unix 时间戳以秒为单位，因此只需将相应的秒数添加到时间戳中：
$timeInFuture = time() + (60 * 60 * 24);

You could use the DateTimeclass as well:
您也可以使用DateTime类：
$timestamp = mktime(15, 30, 00, 3, 28, 2015);
$d = new DateTime();
$d->setTimestamp($timestamp);
Add a Period of 1Day:
添加P的eriod 1个dAY：
$d->add(new DateInterval('P1D'));
echo $d->format('c');
See DateIntervalfor more details.

As you have said if you want to add 24 hours to the timestamp for right now then simply you can do:
正如您所说，如果您现在想为时间戳添加 24 小时，那么您只需执行以下操作：
<?php echo strtotime('+1 day'); ?>
Above code will add 1 day or 24 hours to your current timestamp.
上面的代码将为您当前的时间戳添加 1 天或 24 小时。
in place of +1 dayyou can take whatever you want, As php manualsays strtotimecan Parse about any English textual datetime description into a Unix timestamp.
代替+1 day你可以随心所欲，正如php 手册所说，strtotime可以将任何英文文本日期时间描述解析为 Unix 时间戳。
examples from the manual are as below:
手册中的示例如下：
<?php
echo strtotime("now"), "\n";
echo strtotime("10 September 2000"), "\n";
echo strtotime("+1 day"), "\n";
echo strtotime("+1 week"), "\n";
echo strtotime("+1 week 2 days 4 hours 2 seconds"), "\n";
echo strtotime("next Thursday"), "\n";
echo strtotime("last Monday"), "\n";
?>

$time = date("H:i", strtotime($today . " +5 hours +30 minutes"));
//+5 hours +30 minutes Time Zone +5:30 (Asia/Kolkata)
