php提示PHP Warning: date(): It is not safe to rely on the......安全错误的解决办法
在使用国外主机或者自己安装的php环境的时候，由于没有配置php时区，经常会出现下面问题：
PHP Warning: date(): 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......
或者
PHP Warning: strtotime(): 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......
等时区安全警告提示问题。
这是因为PHP默认获取的时间是格林威治标准时间，所以这个时间会和标准北京时间相差8个小时，对此我们可以用如下办法解决：
1、在页头使用date_default_timezone_set('PRC')设置时区为北京时间即可。
2、在服务器配置文件 php.ini 中设置date.timezone的值为PRC，设置好以后的为：date.timezone=PRC，同时去掉前面的分号，即取消这一行代码的注释。
提示：date_timezone_set — 别名 DateTime::setTimezone()
