[PHP] Warning: date(): ... date_default_timezone_set() ...

如果在code裡面用到date()或time()相關函式,出現以下warning:

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 'Asia/Chongqing' for 'CST/8.0/no DST' instead in /path/to/code.php on line xx

解決方法就是在php.ini設定timezone

$ vim /path/to/php.ini

date.timezone = "Asia/Taipei"

或是在code裡面date()/time()呼叫前指定timezone

$ vim /path/to/code.php

date_default_timezone_set('Asia/Taipei');
