正确解读PHP获取时间错误原因
当我们在运用
今天用echo date("Y-m-d H:i:s")获取系统时间时,发现获取的时间与系统的时间不符。
PHP是外国人开发的,所以经常有很多东西不太好用。研究了一番发现,PHP默认设置的时间是以格林威治时区为标准的,表现是和北京时间差8个小时,因此我们需要将其+8个小时,原理是我们正好位于时区的东8区,所以我们必须把PHP的时区设定改为北京时间。
PHP获取时间错误的解决方法:
打开PHP.ini文件,一般在PHP的安装根目录下,找到其中的;date.timezone,删掉date.timezone前面的分号,并改成date.timezone = PRC。存盘,并重新启动Apahce服务(有时用Apache的restart功能会有问题,建议先stop然后再start)
重新检验一下echo date("Y-m-d H:i:s")。 是不是时间恢复正常了。
如果无法改动PHP.ini文件,也可以在输出时间之前使用date_default_timezone_set()设置时区
date_default_timezone_set('Asia/Shanghai');
函数
date_default_timezone_set(timezone)与date_default_timezone_get()
PHP获取时间错误的问题看似简单,但是却不容忽视。希望大家能在以后的编程中注意这些小缺憾。
