HomeBackend DevelopmentPHP TutorialPHP时间戳格式全部汇总 (获取时间、时间戳)_php实例

PHP语言中的函数有许多种,各种应用方式不同,实现的功能也不尽相同。希望对新手的学习有所帮助!

一,PHP时间戳函数获取指定日期的unix时间戳 strtotime(”2009-1-22″) 示例如下:

echo strtotime(”2009-1-22″) 结果:1232553600

说明:返回2009年1月22日0点0分0秒时间戳

二,PHP时间戳函数获取英文文本日期时间 示例如下:

便于比较,使用date将当时间戳与指定时间戳转换成系统时间

(1)打印明天此时的时间戳strtotime(”+1 day”)

当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25

指定时间:echo date(”Y-m-d H:i:s”,strtotime(”+1 day”)) 结果:2009-01-23 09:40:25

(2)打印昨天此时的时间戳strtotime(”-1 day”)

当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25

指定时间:echo date(”Y-m-d H:i:s”,strtotime(”-1 day”)) 结果:2009-01-21 09:40:25

(3)打印下个星期此时的时间戳strtotime(”+1 week”)

当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25

指定时间:echo date(”Y-m-d H:i:s”,strtotime(”+1 week”)) 结果:2009-01-29 09:40:25

(4)打印上个星期此时的时间戳strtotime(”-1 week”)

当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25

指定时间:echo date(”Y-m-d H:i:s”,strtotime(”-1 week”)) 结果:2009-01-15 09:40:25

(5)打印指定下星期几的时间戳strtotime(”next Thursday”)

当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25

指定时间:echo date(”Y-m-d H:i:s”,strtotime(”next Thursday”)) 结果:2009-01-29 00:00:00

(6)打印指定上星期几的时间戳strtotime(”last Thursday”)

当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25

指定时间:echo date(”Y-m-d H:i:s”,strtotime(”last Thursday”)) 结果:2009-01-15 00:00:00

(7)打印前一天零点的时间戳

$ystd = strtotime('-1 day'); // 昨天这个时刻的时间戳
$ystd = date("Y-m-d", $ystd); // 昨天的日期d

$ystd = strtotime($ystd." 00:00:00"); // 昨天凌晨24点整的时间戳

以上PHP时间戳函数示例可知,strtotime能将任何英文文本的日期时间描述解析为Unix时间戳,我们结合mktime()或date()格式化日期时间获取指定的时间戳,实现所需要的日期时间。

以上这篇PHP时间戳格式全部汇总 (获取时间、时间戳)就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持脚本之家。

What is a session in PHP, and why are they used?What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AM

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

What steps would you take if sessions aren't working on your server?What steps would you take if sessions aren't working on your server?May 03, 2025 am 12:19 AM

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
