执行phpinfo();时提示：
Warning: phpinfo() [function.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 in /usr/local/apache2/htdocs/www/index.php on line 3
解决办法：
vi /usr/local/php/etc/php.ini
找到date.timezone =
设置为date.timezone = Asia/Chongqing
