Time calculation in php (add 10 hours)?
提问by myphpsql00
I get the time:
我得到了时间:
$today = time();
$date = date('h:i:s A', strtotime($today));
if the current time is "1:00:00 am", how do i add 10 more hours to become 11:00:00 am??
如果当前时间是“1:00:00 am”,我如何再增加 10 个小时变成 11:00:00 am??

strtotime()gives you a number back that represents a time in seconds. To increment it, add the corresponding number of seconds you want to add. 10 hours = 60*60*10 = 36000, so...
strtotime()给你一个数字,表示以秒为单位的时间。要增加它,请添加您要添加的相应秒数。10 小时 = 60*60*10 = 36000,所以...
$date = date('h:i:s A', strtotime($today)+36000); // $today is today date
Edit: I had assumed you had a string time in $today - if you're just using the current time, even simpler:
编辑:我假设你在 $today 中有一个字符串时间 - 如果你只是使用当前时间,甚至更简单:
$date = date('h:i:s A', time()+36000); // time() returns a time in seconds already

$tz = new DateTimeZone('Europe/London');
$date = new DateTime($today, $tz);
$date->modify('+10 hours');
// use $date->format() to outputs the result.
see DateTime Class(PHP 5 >= 5.2.0)
请参阅DateTime 类(PHP 5 >= 5.2.0)

$date = date('h:i:s A', strtotime($today . ' + 10 hours'));
$date = date('h:i:s A', strtotime($today . ' + 10 hours'));

Full code that shows now and 10 minutes added.....
现在显示的完整代码和 10 分钟添加.....
$nowtime = date("Y-m-d H:i:s");
echo $nowtime;
$date = date('Y-m-d H:i:s', strtotime($nowtime . ' + 10 minute'));
echo "<br>".$date;

In order to increase or decrease time using strtotimeyou could use a Relative formatin the first argument.
为了增加或减少使用时间,strtotime您可以在第一个参数中使用相对格式。
In your case to increase the current timeby 10 hours:
在您的情况下,将当前时间增加 10 小时:
$date = date('h:i:s A', strtotime('+10 hours'));
In case you need to apply the change to another timestamp, the second argument can be specified.
如果您需要将更改应用于另一个时间戳,则可以指定第二个参数。
Note:
笔记:
Using this function for mathematical operations is not advisable. It is better to use
DateTime::add()and DateTime::sub() in PHP 5.3 and later, or DateTime::modify() in PHP 5.2.
不建议将此函数用于数学运算。
DateTime::add()在 PHP 5.3 及更高版本中最好使用和 DateTime::sub(),或者在 PHP 5.2 中使用 DateTime::modify()。
So, the recommended waysince PHP 5.3:
所以,自 PHP 5.3 起推荐的方式:
$dt = new DateTime(); // assuming we need to add to the current time
$dt->add(new DateInterval('PT10H'));
$date = $dt->format('h:i:s A');
or using aliases:
或使用别名:
$dt = date_create(); // assuming we need to add to the current time
date_add($dt, date_interval_create_from_date_string('10 hours'));
$date = date_format($dt, 'h:i:s A');
In all cases the default time zone will be used unless a time zone is specified.
在所有情况下,除非指定时区,否则将使用默认时区。
