PHP Warning: phpinfo(): It is not safe to rely on the system's timezone setting

错误描述： 
PHP Warning:  phpinfo(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'UTC' for '8.0/no DST' instead in C:\info.php on line 4 

 

打开php.ini 配置文件 
找到 
[Date] 
; Defines the default timezone used by the date functions 
; http://php.net/date.timezone 
;date.timezone = 


修改为： 
[Date] 
; Defines the default timezone used by the date functions 
; http://php.net/date.timezone 
date.timezone ="PRC"

一定要加引号否则还会报错！

然后记得重启apache!
