使用php的朋友会发现如果你刚安装好apache与php环境,会发现你系统的时间与我们中国时间是有区别的,一般情况是相隔8小时哦,下面我来介绍PHP设置时区设置方法总结。
方法一,在php页面设置时区
在页面最前面加上下面应用一种都是可以的
date_default_timezone_set用法如下
date_default_timezone_set
(PHP 5 >= 5.1.0RC1)
date_default_timezone_set -- 设定用于一个脚本中所有日期时间函数的默认时区
说明
bool date_default_timezone_set ( string timezone_identifier )
date_default_timezone_set() 设定用于所有日期时间函数的默认时区。
用法
代码如下 | 复制代码 |
1 date_default_timezone_set('Asia/Shanghai');//'Asia/Shanghai' 亚洲/上海 2 date_default_timezone_set('Asia/Chongqing');//其中Asia/Chongqing'为“亚洲/重庆” 3 date_default_timezone_set('PRC');//其中PRC为“中华人民共和国” 4 ini_set('date.timezone','Etc/GMT-8'); 5 ini_set('date.timezone','PRC'); 6 ini_set('date.timezone','Asia/Shanghai'); 7 ini_set('date.timezone','Asia/Chongqing'); |
Asia/Shanghai – 上海
Asia/Chongqing – 重庆
Asia/Urumqi – 乌鲁木齐
Asia/Hong_Kong – 香港
Asia/Macao – 澳门
Asia/Taipei – 台北
Asia/Singapore – 新加坡
如果你有服务器管理权限,我们可以在在PHP.INI中设置时区
代码如下 | 复制代码 |
date.timezone = PRC |
去掉前面的分号 然后重启apache
可能碰到的一些问题
1.Warning: strftime(): 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.
2.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.
3.Notice: date_default_timezone_set(): Timezone ID 'Asia/Shanghai' is invalid
解决办法
代码如下 | 复制代码 |
date_default_timezone_set('Asia/Shanghai');//'Asia/Shanghai' 亚洲/上海 date_default_timezone_set('Asia/Chongqing');//其中Asia/Chongqing'为“亚洲/重庆” date_default_timezone_set('PRC');//其中PRC为“中华人民共和国” |
