在調試PHP源碼時，使用<?php echo date('Ymd',time()).rand(10000000,99999999); ?> 設置訂單隨機數，出現以下錯誤。

PHP message: PHP Warning: phpinfo(): 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

解決方法：

在php.ini里加上

date.timezone = "Asia/Shanghai"(去掉前面的;)
