php-比给定的日期时间早一小时 [英] php - One Hour Earlier Than Given Datetime

问题描述

我在这里有问题.

假设我有这种日期时间.

Supposed I have this kind of datetime.

$date = strtotime($date);

我需要将其转换为Unix时间戳格式，但是要早一小时..我尝试了

I need this to be converted into the Unix-timestamp format but one hour earlier..I tried

$date = strtotime($date-86400)

，但是在我看来这是错误的.我潜入桌子时返回0.

, but seemed to me it is wrong. It returned 0 when I sneaked into the table.

实现此目标的合适方法是什么?

What is the appropriate way to achieve this?

谢谢.

推荐答案

strtotime将为您提供日期的unix时间戳.然后从该时间戳记中减去小时:

strtotime will give you the unix timestamp of your date. From this timestamp, you then subtract your hour:

$date = strtotime($date) - 3600; // 3600 = 60 * 60

如果您调用strtotime($date - 3600)，这就像获取-3600的时间(例如strtotime(-3600))，这是没有意义的，因为strtotime希望将字符串作为第一个参数.

If you call strtotime($date - 3600), it's like obtaining the time for -3600 (e.g. strtotime(-3600)) which makes no sense because strtotime expects a string as first argument.
