locale
If
locale
isnull
or the empty string""
, the locale names will be set from the values of environment variables with the same names as the above categories, or from "LANG".If
locale
is"0"
, the locale setting is not affected, only the current setting is returned.If
locale
is an array or followed by additional parameters then each array element or parameter is tried to be set as new locale until success. This is useful if a locale is known under different names on different systems or for providing a fallback for a possibly not available locale....
(可使用字符串或数组参数进行尝试直到设置成功。)
Note:
在Windows中,setlocale(LC_ALL, )要从系统中的区域/语言设置(通过控制面板访问) 。
返回值
Returns the new current locale, or false
if the locale functionality is
not implemented on your platform, the specified locale does not exist or
the category name is invalid.
An invalid category name also causes a warning message. Category/locale names can be found in » RFC 1766 and » ISO 639. Different systems have different naming schemes for locales.
Note:
The return value of setlocale() depends on the system that PHP is running. It returns exactly what the system
setlocale
function returns.

范例
Example #1 setlocale() Examples
<?php/* Set locale to Dutch */setlocale(LC_ALL, 'nl_NL');/* Output: vrijdag 22 december 1978 */echo strftime("%A %e %B %Y", mktime(0, 0, 0, 12, 22, 1978));/* try different possible locale names for german as of PHP 4.3.0 */$loc_de = setlocale(LC_ALL, 'de_DE@euro', 'de_DE', 'de', 'ge');echo "Preferred locale for german on this system is '$loc_de'";?>
Example #2 setlocale() Examples for Windows
<?php/* Set locale to Dutch */setlocale(LC_ALL, 'nld_nld');/* Output: vrijdag 22 december 1978 */echo strftime("%A %d %B %Y", mktime(0, 0, 0, 12, 22, 1978));/* try different possible locale names for german as of PHP 4.3.0 */$loc_de = setlocale(LC_ALL, 'de_DE@euro', 'de_DE', 'deu_deu');echo "Preferred locale for german on this system is '$loc_de'";?>
注释
Warning The locale information is maintained per process, not per thread. If you are running PHP on a multithreaded server API like IIS or Apache on Windows, you may experience sudden changes in locale settings while a script is running, though the script itself never called setlocale(). This happens due to other scripts running in different threads of the same process at the same time, changing the process-wide locale using setlocale().
Tip
Windows users will find useful information about
locale
strings at Microsoft's
MSDN website. Supported language strings can be found
in the
» language strings documentation
and supported country/region strings in the
» country/region strings documentation.
