Worked for me..
为我工作..
$timestamp = strtotime('10:09') + 60*60;
$time = date('H:i', $timestamp);
echo $time;//11:09
Explanation:
解释：
strtotime('10:09')creates a numerical timestamp in seconds, something like 1510450372. Simply add or remove the amount of seconds you need and use date()to convert it back into a human readable format.
strtotime('10:09')创建一个以秒为单位的数字时间戳，类似于1510450372. 只需添加或删除您需要的秒数date()，并将其转换回人类可读的格式。
$timestamp = strtotime('10:09') + 60*60; // 10:09 + 1 hour
$timestamp = strtotime('10:09') + 60*60*2; // 10:09 + 2 hours
$timestamp = strtotime('10:09') - 60*60; // 10:09 - 1 hour
time()also creates a numerical timestamp but for right now. You can use it in the same way.
time()还创建一个数字时间戳，但现在。您可以以相同的方式使用它。
$timestamp = time() + 60*60; // now + 1 hour

You can do like this
你可以这样做
echo date('Y-m-d H:i:s', strtotime('4 minute'));
echo date('Y-m-d H:i:s', strtotime('6 hour'));
echo date('Y-m-d H:i:s', strtotime('2 day'));

$time = '10:09';
$timestamp = strtotime($time);
$timestamp_one_hour_later = $timestamp + 3600; // 3600 sec. = 1 hour
// Formats the timestamp to HH:MM => outputs 11:09.
echo strftime('%H:%M', $timestamp_one_hour_later);
// As crolpa suggested, you can also do
// echo date('H:i', $timestamp_one_hour_later);
Check PHP manual for strtotime(), strftime()and date()for details.
有关详细信息，请查看 PHP 手册中的strtotime()、strftime()和date()。
BTW, in your initial code, you need to add some quotes otherwise you will get PHP syntax errors:
顺便说一句，在您的初始代码中，您需要添加一些引号，否则您将收到 PHP 语法错误：
$time = 10:09; // wrong syntax
$time = '10:09'; // syntax OK
$time = date(H:i, strtotime('+1 hour')); // wrong syntax
$time = date('H:i', strtotime('+1 hour')); // syntax OK

It is weird that no one has suggested the OOP way:
奇怪的是，没有人提出 OOP 方式：
$date = new \DateTime(); //now
$date->add(new \DateInterval('PT3600S'));//add 3600s / 1 hour
OR
或者
$date = new \DateTime(); //now
$date->add(new \DateInterval('PT60M'));//add 60 min / 1 hour
OR
或者
$date = new \DateTime(); //now
$date->add(new \DateInterval('PT1H'));//add 1 hour
Extract it in string with format:
将其提取为字符串格式：
var_dump($date->format('Y-m-d H:i:s'));
I hope it helps
我希望它有帮助

You can use:
您可以使用：
$time = strtotime("10:09") + 3600;
echo date('H:i', $time);
Or date_add: http://www.php.net/manual/en/datetime.add.php

Beware of adding 3600!! may be a problem on day change because of unix timestamp format uses moth before day.
小心加3600！！由于 unix 时间戳格式在一天之前使用蛾，因此可能会在日期更改时出现问题。
e.g. 2012-03-02 23:33:33 would become 2014-01-13 13:00:00 by adding 3600 better use mktime and date functions they can handle this and things like adding 25 hours etc.
例如 2012-03-02 23:33:33 将变成 2014-01-13 13:00:00 通过添加 3600 更好地使用 mktime 和 date 函数，他们可以处理这个问题以及添加 25 小时等。
