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 the timezone 'UTC' for now, but please set date.timezone to select your timezone. PHP 5.3 + 需要在 php.ini 文件中配置 timezone, 或在调用 date() 函数之前使用 date_default_timezone_set() 方法设置 timezone Case A: 在 php.ini 文件中配置 timezone

#grep -B 1 timezone ./php.ini
[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = "Asia/Shanghai"

之后重启你的 web/php 服务 Case B: 在调用 date() 函数之前通过 date_default_timezone_set() 设置 timezone eg:

/* set data timezone */
date_default_timezone_set("PRC");
$years = date('Y');
