php date(): It is not safe 警告解決

 升級php版本從PHP5.2.17 到 PHP 5.3.21 後出現如下儲存
 
 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. …

 

解決辦法

 

 在程式中使用

 date_default_timezone_set('PRC');

 

 或者在php.ini裡找到date.timezone這行，把值改成PRC，如date.timezone = PRC。如果沒有這一行直接加上就好

  [Date]; Defines the default timezone used by the date functions; http://php.net/date.timezonedate.timezone = America/New_York
