PHP date()函数警告: It is not safe to rely on the system解决方法

近来总是有系统邮件提示，开始没在意，后来不断提示就看了一下。提示以下信息

代码如下：

PHP 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 gett

ing this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Chongqing' for 'CST/8.0/no DST' instead in /data0/htdocs/www.qttc.net/function/function.php on line 542

第一种

在页面头部加入以下语句

代码如下：

date_default_timezone_set("PRC");

第二种

在php.ini里找到date.timezone这行，把值改成PRC，如date.timezone = PRC。如果没有这一行直接加上就好。最后重启WEB服务器与PHP即可。
