HomeBackend DevelopmentPHP Tutorial请教前辈时间戳用php转换成日期和用mysql函数转换成日期不一致的问题

mysql数据库有一表infor,该表下有一字段为time字段,类型为int(10),该字段下有一条数据位:1383346800


问题来了:
我用php函数echo date("Y-m-d H:i:s",1383346800);  运行结果是:2013-11-01 23:00:00

而用mysql函数select from_unixtime(1383346800);   运行结果是:2013-11-02 07:00:00
如图:


为何同一个时间戳php和mysql是两个结果?哪个结果才是对的? 求前辈帮看下,两种方法我都需要,因为我要用这两个方法比较结果,能让两种结果一致吗,还是就是不能? 感谢好心人帮我了!


回复讨论(解决方案)

两个都对,都没有错!
只是参照点不同而已
对于 1383346800 有

格林威治时间 2013-11-01 23:00:00
正好差一个东八区时差 8 小时

时区问题,你的php参照的是格林威治标准时间,与本地时间相差8小时。
date_default_timezone_set('PRC')  设置下时区或者php.ini 中 更改date.timezone=PRC 的值就行了。

1 date_default_timezone_set('Asia/Shanghai');//'Asia/Shanghai'   亚洲/上海

2 date_default_timezone_set('Asia/Chongqing');//其中Asia/Chongqing'为“亚洲/重庆”

3 date_default_timezone_set('PRC');//其中PRC为“中华人民共和国”

获得时间前,设置下时区,就ok了

这里有很好的介绍:日期/时间函数的行为受到 php.ini 中设置的影响。
那么就有如2楼所说的两种方法解决.

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
