php获取当地时间 time zone

 

PHP5.2.4之前的版本无需设置时区。下面是修改PHP时区的三个办法。

1、修改PHP.ini这个文件
找到date.timezone这行，去掉前面的分号，改成：

Java代码

1. date.timezone = Asia/Shanghai 

2、修改 .htaccess文件
修改.htaccess文件有两种办法，下面的两条语句只要有一条即可

Java代码

1. php_value date.timezone Asia/Shanghai 
2. SetEnv TZ Asia/Shanghai 

3、修改PHP代码
也是下面的两条语句只要其中的一句即可

Php代码

1. date_default_timezone_set('Asia/Shanghai'); 
2. ini_set('date.timezone','Asia/Shanghai'); 

例如： <?php date_default_timezone_set('Asia/Shanghai'); ?>

Php代码

1. <?php 
2. include('tz.php'); 
4. echo get_localtime(time(),'Asia/Hong_Kong'); // local time
6. //get_alltime(time()); // global time
8. ?> 

具体见附件；

例外，也收集了一些有关时区的动动；

1. PHP TimeZone Array

Php代码

1. <?php 
3. $timezoneTable = array(

2. 获取GMT标准时间

Php代码

1. echo 'GMT :'.date("m/d/Y H:i", time() - date("Z"));  

3. GMT to local time

下面的程序结合上面两条，将更加有用。

Java代码

1. <?php 
3. // I am using the convention (assumption) of "07/04/2004 14:45"
4. $processdate = "12/04/2010 14:45"; //  date("m/d/Y H:i", time() - date("Z")) is GMT
7. // gmttolocal is a function
8. // i am passing it 2 parameters:
9. // 1)the date in the above format and
10. // 2)time difference as a number; -5 in our case (GMT to CDT)
11. echo gmttolocal($processdate,-5);  
13. function gmttolocal($mydate,$mydifference)   
14. { 
15. // trying to seperate date and time
16.     $datetime = explode(" ",$mydate); 
18. // trying to seperate different elements in a date
19.     $dateexplode = explode("/",$datetime[0]); 
21. // trying to seperate different elements in time
22.     $timeexplode = explode(":",$datetime[1]); 
25. // getting the unix datetime stamp
26.     $unixdatetime = mktime($timeexplode[0]+$mydifference,$timeexplode[1],0,$dateexplode[0],$dateexplode[1],$dateexplode[2]); 
28. // return the local date
29. return date("m/d/Y H:i",$unixdatetime); 
30. } 

什么是GMT？

格林尼治标准时间（GMT）

由来

由于地球轨道并非圆形，其运行速度又随着地球与太阳的距离改变而出现变化，因此视太阳时欠缺均匀性。视太阳日的长度同时亦受到地球自转轴相对轨道面的倾 斜度所影响。为着要纠正上述的不均匀性，天文学家计算地球非圆形轨迹与极轴倾斜对视太阳时的效应。平太阳时就是指经修订后的视太阳时。在格林尼治子午线上 的平太阳时称为世界时(UT0)，又叫格林尼治平时(GMT)。

北京时间与GMT时间关系

GMT是中央时区,北京在东8区,相差8个小时 所以北京时间=GMT时间+八小时 Greenwich mean time 【天】格林尼治标准时间
