PHP生成的时区列表不完整 [英] Incomplete list of timezones generated by PHP

问题描述

我已经尝试生成完整的时区集，如 http://php.net中指定的那样/manual/en/timezones.php (UTC除外)，方法是使用以下代码:

I've tried generating the complete set of timezones as specified in http://php.net/manual/en/timezones.php (except UTC) by using the following code:

$zones = timezone_identifiers_list();

print_r($zones);

但是此列表似乎跳过了约50个区域，例如:Pacific/Samoa(与 http ://php.net/manual/en/timezones.php )

But this list seems to skip ~ 50 regions, eg: Pacific/Samoa (as compared to http://php.net/manual/en/timezones.php)

我们在做什么错了?

phpinfo()显示:

phpinfo() shows:

PHP Version 5.3.4
Apache Version  Apache/2.2.3 (CentOS) 

$ uname -r
2.6.18-028stab070.14

推荐答案

您的时区数据库可能不是最新的.

Your timezone database might not be up-to-date.

请尝试点击受支持的时区列表页底部的链接:

Try following the link at the bottom of the List of Supported Timezones page :

时区的最新版本 可以通过PECL的数据库安装» timezonedb .

The latest version of the timezone database can be installed via PECL's » timezonedb.

在注释后以更新您的时区数据库，就像在Linux系统上一样，您可以使用pecl命令(我刚刚在我的Ubuntu机器上尝试过此操作) :

Edit after the comments : to update your timezone database, as you are on a Linux system, you can use the pecl command (I just tried this on my Ubuntu machine) :

pecl upgrade timezonedb

这将下载新版本并进行编译.

This will download the new version, and compile it.

然后，如果启用了新的timezonedb扩展名，则您的PHP应该使用一个最新的数据库:

Then, if you enable the new timezonedb extension, your PHP should use an uptodate database :

php -dextension=timezonedb.so -i | grep Timezone
"Olson" Timezone Database Version => 2011.5
Timezone Database => external
Alternative Timezone Database => enabled
Timezone Database Version => 2011.5

如果我尝试不启用该新扩展名，则会得到与以前相同的东西:

If I try without enabling that new extension, I get the same kind of thing you had before :

php -i | grep Timezone
"Olson" Timezone Database Version => 0.system
Timezone Database => internal
