在用PHP5.3以上的PHP版本時，只要是涉及時間的會報一個
"PHP Warning: date() [function.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 'UTC' for '8.0/no DST' instead in"
解決方法：
修改php.ini。打開php5.ini查找date.timezone 去掉前面的分號修改成爲：date.timezone =PRC
