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!

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.
