PHP date("Y-m-d H:i:s");获取当前时间 差8小时解决办法

(转)http://subin.org.cn/blog/post/430.html

原因:?? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?

??????? 从php5.1.0开始,php.ini里加了date.timezone这个选项,并且默认情况下是关闭的也就是显示的时间(无论用什么php命令)都是格林威治标准时间和我们的时间(北京时间)差了正好8个小时。

??????? 关于timezone 大陆内地可用的值是:Asia/Chongqing ,Asia/Shanghai ,Asia/Urumqi ,PRC(依次为重庆,上海,乌鲁木齐,中华人民共和国)港台地区可用:Asia/Macao ,Asia/Hong_Kong ,Asia/Taipei (依次为澳门,香港,台北)还有新加坡:Asia/Singapore其它:Etc/GMT-8 ,Singapore ,Hongkong

解决方法一:

??????? 再添加时间前 插入:CODE:(好像不用加)?date_default_timezone_set(PRC);

解决方法二:

??????? echo date("Y-m-d H:i:s",?time()+8*60*60);

解决方法三(修改php.ini文件):

??????? 找到php.ini中的“;date.timezone =”这行,将“;”去掉,改成“date.timezone = PRC”(PRC:People's Republic of China 中华人民共和国),重启Apache,问题解决。

附:date时间格式

date("Y-m-d H:i:s"); 显示的格式: 年-月-日 小时:分钟:秒
