Another way - without all the math and, in my opinion, reads better.
另一种方式 - 没有所有的数学,在我看来,阅读更好。
$hour_ago = strtotime('-1 hour');

If you're looking for how to display the time in a human readable format, these examples will help:
如果您正在寻找如何以人类可读的格式显示时间,这些示例将有所帮助:
$livetime = date('H:i:s', time() - 3600); // 16:00:00
$livetime = date('g:iA ', time() - 3600); // 4:00PM

convert your date to strtotime and then subtract one hour from it
将您的日期转换为 strtotime,然后从中减去一小时
$now = date('Y-m-d H:i:s');
$time = strtotime($now);
$time = $time - (60*60); //one hour
$beforeOneHour = date("Y-m-d H:i:s", $time);

You could use the date_create function along with the date_sub function like I have shown here below: -
您可以将 date_create 函数与 date_sub 函数一起使用,如下所示:-
$currentTime = date_create(now());
$modifyTime = date_sub($currentTime,date_interval_create_from_date_string("1 hour"));
$liveTime = $modifyTime->format('Y-m-d H:i:s');

Here you go:
干得好:
<?php
$now = time();
echo strftime("%c",$now) . "\n";
$livetime = $now-3600;
echo strftime("%c",$livetime) . "\n";
?>

Current time is equal to time()
(current time given in seconds after Unix epoch).
当前时间等于time()
(Unix 纪元后的当前时间以秒为单位)。
Thus, to calculate what you need, you need to perform calculation: time() - 60*60
(current time in seconds minus 60 minutes times 60 seconds).
因此,要计算您需要的内容,您需要执行计算:(time() - 60*60
以秒为单位的当前时间减去 60 分钟乘以 60 秒)。
$time_you_need = time() - 60*60;

First convert hours into seconds (3600
) then use the following:
首先将小时转换为秒 ( 3600
) 然后使用以下内容:
$your_date = date('F jS, Y',time() - 3600);
