之前一直用这个方法获取当前时间:

1
$now = new DateTime();

不过貌似在「PHP 5.3.3」中，会报这样的错误

PHP Fatal error: Uncaught exception 'Exception' with message 'DateTime::__construct(): 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 'Asia/Chongqing' for 'CST/8.0/no DST' instead’ in **

于是按照要求，执行

1
2
date_default_timezone_set('Asia/Chongqing');
$now = new DateTime();

即可。

经过搜索，也可以修改php.ini文件，找到「date.timezone」，修改一下

1
date.timezone = Asia/Chongqing

然后重启apache即可
