Question

为什么在php.ini中设置了date.timezone = PRC 后时区仍然出错

Answer 1

PHP环境如果修改了还重新启动APACHE才能生效的哦，所以php.ini中设置了date.timezone = PRC 后你要重新下环境，再测试下是不是生效了。

Answer 2

In order of preference, this function returns the default timezone by:

Reading the timezone set using the date_default_timezone_set() function (if any)

Reading the TZ environment variable (if non empty)

Reading the value of the date.timezone ini option (if set)

Querying the host operating system (if supported and allowed by the OS)

就在date函数中，第一个参数可以设timezone的
date("O +0800", time());
