setlocale

(PHP 4, PHP 5, PHP 7)

setlocale — 设置地区信息

说明

setlocale ( int $category , string $locale [, string $... ] ) : string

setlocale ( int $category , array $locale ) : string

设置地区信息。

参数

category

category 命名常量指定的受区域设置的功能类别:

LC_ALL 所有的设置
LC_COLLATE 字符串比较, 详见 strcoll()
LC_CTYPE 字符串的分类与转换, 参见例子 strtoupper()
LC_MONETARY 等同 localeconv()
LC_NUMERIC 对于小数点的分隔 (另请参见 localeconv())
LC_TIME 时间与格式 strftime()
LC_MESSAGES 系统响应 (如果PHP使用libintl编译)

locale

If locale is NULL 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.

更新日志

版本	说明
5.3.0	This function now throws an `E_DEPRECATED` notice if a string is passed to the `category` parameter instead of one of the LC_* constants.

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.

tim dot peters at live dot com 01-May-2019 09:18


Maybe obvious, but I would expect that setlocale constantes (LC_*) would be bitwise, but they're not.



In example, doing this:



<?php

    setlocale(LC_TIME + LC_COLLATE, 'nl');



    echo setlocale(LC_ALL, 0);

?>

would cause the following result:



LC_CTYPE=C;LC_NUMERIC=C;LC_TIME=C;LC_COLLATE=C;LC_MONETARY=C;LC_MESSAGES=nl;LC_PAPER=C;

LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=C;LC_IDENTIFICATION=C



Note that LC_MESSAGES has changed, instead of LC_TIME and LC_COLLATE. (Because LC_TIME + LC_COLLATE = LC_MESSAGES).



Instead you would need to specify them individually, if you don't wish to use LC_ALL:



<?php

    setlocale(LC_TIME, 'nl');

    setlocale(LC_COLLATE, 'nl');



    echo setlocale(LC_ALL, 0);

?> LC_CTYPE=C;LC_NUMERIC=C;LC_TIME=nl;LC_COLLATE=nl;LC_MONETARY=C;LC_MESSAGES=C;LC_PAPER=C;

LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=C;LC_IDENTIFICATION=C

If you have Locales installed and things won't work check the spelling: for German all the comments suggested "setlocale(LC_TIME, "de_DE.utf8")", but it has to be "setlocale(LC_TIME, "de_DE.UTF-8")"-> UTF-8 instead of utf8.

The categories are more explained at the manpage of locale(7):

I got return value [ string(1) "C" ] from CentOS6 after 

calling  setlocale(LC_ALL, 0);



I got totally different return value

 [ string(170) "LC_CTYPE=ja_JP.UTF8;

LC_NUMERIC=C;

LC_TIME=C;

LC_COLLATE=C;

LC_MONETARY=C;

LC_MESSAGES=C;

LC_PAPER=C;

LC_NAME=C;

LC_ADDRESS=C;

LC_TELEPHONE=C;

LC_MEASUREMENT=C;

LC_IDENTIFICATION=C"] from another  CentOS6

after calling the same method  setlocale(LC_ALL, 0);



Could someone tell me what makes the result different ?

My script runs a loop that changes the locale (multilingual application). I've noticed that on some random occasion the locale still hasn't changed despite the setlocale() function being executed a step earlier. I had to add wait time for this condition. Interestingly enough, this was the case only with the 'nl_NL.UTF8' locale.



<?php

//some code

$this->counter = 0;

// some code

$this->locale = 'nl_NL.UTF8';

setlocale(LC_ALL, $this->locale);

    $this->counter++;

    if ($this->locale !== setlocale(LC_CTYPE, 0)) { // Locale not changed yet.

      if ($this->counter > 10) {

        return;

      }

      sleep(1);

    }

// some code

?>

For Windows users complaining about setlocale. 



The locale argument to the setlocale function takes the following form:

setlocale( LC_ALL, "<language>_<country>.<code_page>" );



in short, if you  want use for example: es_CO.UTF-8 it must be in Windows: Spanish_Colombia.1252



The code page 1252 is ISO-8859-1 (windows-1252    ANSI Latin 1; Western European (Windows)



Windows use different languages code from Unix, for example, es_CO becomes es-CO or Spanish_Colombia, also it doesn't support UTF-8 charset as is shown in their website: https://msdn.microsoft.com/en-us/library/x99tb11d(v=vs.140).aspx



"The set of available locale names, languages, country/region codes, and code pages includes all those supported by the Windows NLS API except code pages that require more than two bytes per character, such as UTF-7 and UTF-8. If you provide a code page value of UTF-7 or UTF-8, setlocale will fail, returning NULL."



Please check the updated website of language and code pages:

In Windows some times setlocale don't work, it return a empty array, buts the locale is set. I found that apache start before windows "load" locales, you must restart apache to solve this.

RobQuist 28-Nov-2013 02:51


In addition to russ, about getting / backing up the locale:

I'm using this in unit-tests. I wanted to test something based on locale, and reset the locale after the tests were done.



Yet there were some errors;

* setlocale doesn't like strings anymore. You need to use constants.

* Some contants don't exist anymore. 



Here's an updated piece of code:



<?php

$originalLocales = explode(";", setlocale(LC_ALL, 0));

setlocale(LC_ALL, 'nl_NL.UTF-8');



//Do something here



//Recover to the default setting

        $skipConstants = array( //these will be returned by setlocale(LC_ALL, 0), but don't exist anymore.

            'LC_PAPER',

            'LC_NAME',

            'LC_ADDRESS',

            'LC_TELEPHONE',

            'LC_MEASUREMENT',

            'LC_IDENTIFICATION'

        );



        foreach ($originalLocales as $localeSetting) {

            if (strpos($localeSetting, "=") !== false) {

                list ($category, $locale) = explode("=", $localeSetting);

            } else {

                $category = LC_ALL;

                $locale   = $localeSetting;

            }



            if (!in_array($category, $skipConstants)) {

                setlocale(constant($category), $locale); //Using strings is deprecated.

            }

        }

data dot ocean dot italia at gmail dot com 20-Jan-2013 07:42


Instead, using php with IIS, I had to use this line for Italian language...



<?php setlocale(LC_ALL, 'Italian_Italy.1250'); ?>

russ at eatmymonkeydust dot com 08-Dec-2011 03:45


If you are looking for a getlocale() function simply pass 0 (zero) as the second parameter to setlocale().



Beware though if you use the category LC_ALL and some of the locales differ as a string containing all the locales is returned:



<?php

echo setlocale(LC_ALL, 0);



// LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=C;LC_COLLATE=C;LC_MONETARY=C;LC_MESSAGES=C;LC_PAPER=C;LC_NAME=C;

// LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=C;LC_IDENTIFICATION=C



echo setlocale(LC_CTYPE, 0);



// en_US.UTF-8



setlocale(LC_ALL, "en_US.UTF-8");

echo setlocale(LC_ALL, 0);



// en_US.UTF-8



?>



If you are looking to store and reset the locales you could do something like this:



<?php



$originalLocales = explode(";", setlocale(LC_ALL, 0));

setlocale(LC_ALL, "nb_NO.utf8");



// Do something



foreach ($originalLocales as $localeSetting) {

  if (strpos($localeSetting, "=") !== false) {

    list ($category, $locale) = explode("=", $localeSetting);

  }

  else {

    $category = LC_ALL;

    $locale   = $localeSetting;

  }

  setlocale($category, $locale); 

}



?>



The above works here (Ubuntu Linux) but as the setlocale() function is just wrapping the equivalent system calls, your mileage may vary on the result.

phcorp 26-Jul-2011 06:16


To find the locale of a Unix system:

<?php system('locale -a') ?>

flavioacvalverde at gmail dot com 15-Jun-2011 09:28


For Portugal I had to use





<?php setlocale(LC_ALL, 'Portuguese_Portugal.1252'); ?>





using php with IIS on Windows server.

tomas dot hampl at gmail dot com 23-Apr-2011 01:35


On Linux, setlocale() depends on the installed locales. To see which locales are available to PHP, run this from the terminal:



"locale -a"



Provided list are all locales that are available on your server for PHP to use. To add a new one, run



locale-gen <locale name> (this may need sudo / root permissions), for example to add a Czech locale, run something like this:



"sudo locale-gen cs_CZ.utf8"



Then you can use this locale declaration:



setlocale(LC_ALL, 'cs_CZ.utf8');

leif at neland dot dk 16-Aug-2010 04:38


Regarding dash'es in locale, it appears they should be omitted entirely.



In /etc/locale.gen I have



da_DK.ISO-8859-15 ISO-8859-15



but locale -a gives 



da_DK.iso885915



which is the format setlocale()  wants.



(Debian)

garygendron at yahoo dot com 28-Jun-2010 08:04


For a php Mysql query, you could also use, for french canadian, in this example :



$query = 'SET lc_time_names = "fr_CA"';

$result = mysql_query($query) or die("Query failed");



$query = 'SELECT @@lc_time_names';

$result = mysql_query($query) or die("Query failed");



$query = 'SELECT id, created, YEAR(created) as year, MONTH(created) as month,' .

' CONCAT_WS(" ", MONTHNAME(created), YEAR(created)) as archive' .            

' FROM #__TABLE as e' .

' GROUP BY archive' .

' ORDER BY id DESC'; 



Your data will be displayed in any locale setting you want. You may even $_GET[lc_time_name] from your multilanguage website.

Omer Sabic 21-Mar-2010 07:27


On Linux/Apache, when you install and try to use a new locale, the setlocale() function with the new locale will fail sometimes, but not always. To furthermore complicate, setlocale() will always complete with any of the previously installed locales. This would seem a really weird behaviour, which you can fix by restarting Apache, as Kari Sderholm aka Haprog mentioned, but I felt it needed to be properly pointed out.

Kari Sderholm aka Haprog 16-May-2009 04:28


It took me a while to figure out how to get a Finnish locale correctly set on Ubuntu Server with Apache2 and PHP5.



At first the output for "locale -a" was this:

C

en_US.utf8

POSIX



I had to install a finnish language pack with

"sudo apt-get install language-pack-fi-base"



Now the output for "locale -a" is:

C

en_US.utf8

fi_FI.utf8

POSIX



The last thing you need to do after installing the correct language pack is restart Apache with "sudo apache2ctl restart". The locale "fi_FI.utf8" can then be used in PHP5 after restarting Apache.



For setting Finnish timezone and locale in PHP use:

<?php

date_default_timezone_set('Europe/Helsinki');

setlocale(LC_ALL, array('fi_FI.UTF-8','fi_FI@euro','fi_FI','finnish'));

?>

wisborg 27-Apr-2009 05:06


It is correct as stated below that it is common that the UTF-8 should be used without the dash. However on some systems (e.g. MacOS 10.4) the dash is essential.

brice/axice/be 20-Feb-2009 05:19


Pay attention to the syntax.


- UTF8 without dash ('-')


- locale.codeset and not locale-codeset.





Stupid newbie error but worth knowing them when starting with gettext.





<?php


$codeset = "UTF8";  // warning ! not UTF-8 with dash '-'


        


// for windows compatibility (e.g. xampp) : theses 3 lines are useless for linux systems 





putenv('LANG='.$lang.'.'.$codeset);


putenv('LANGUAGE='.$lang.'.'.$codeset);


bind_textdomain_codeset('mydomain', $codeset);





// set locale


bindtextdomain('mydomain', ABSPATH.'/locale/');


setlocale(LC_ALL, $lang.'.'.$codeset);


textdomain('mydomain');


?>





where directory structure of locale is (for example) :


locale/fr_FR/LC_MESSAGES/mydomain.mo


locale/en_US/LC_MESSAGES/mydomain.mo





and ABSPATH is the absolute path to the locale dir





further note, under linux systems, it seems to be necessary to create the locale at os level using 'locale-gen'.

Un_passant 16-Nov-2008 03:56


For debian/ubuntu, don't forget the charset UFT8. 



// Works on Ubuntu 8.04 Server

setlocale(LC_TIME, 'fr_FR.UTF8', 'fr.UTF8', 'fr_FR.UTF-8', 'fr.UTF-8');

Leigh Morresi 01-Oct-2008 11:27


Setting locale that is not supported by your system will result in some string operations returning a question mark "?" in your strings where it needs to perform transliteration.



1) Always check the return of setlocale() to ensure it has set to something supported



2) on Linux you can use the "locale -a" command to find a list of supported locales

Arjon 27-Jul-2008 09:12


Please take heed and read the warning above if you are running on a XAMPP or any other Windows apache server! It just took me far too long to figure this out; and all the while there was a warning right on the page.



If you're experiencing shifting locale settings (check with setlocale(LC_ALL,0), returning the current locale stuff) and you're running a windows server, then it's not just you! Again, I urge everyone to read the red, but oh so easy not to read, warning message on this page.

michal dot kocarek at brainbox dot cz 27-Jul-2008 08:33


Note about using UTF-8 locale charset on Windows systems:





According to MSDN, Windows setlocale()'s implementation does not support UTF-8 encoding.





Citation from "MSDN setlocale, _wsetlocale" page (http://msdn.microsoft.com/en-us/library/x99tb11d.aspx):


The set of available languages, country/region codes, and code pages includes all those supported by the Win32 NLS API except code pages that require more than two bytes per character, such as UTF-7 and UTF-8. If you provide a code page like UTF-7 or UTF-8, setlocale will fail, returning NULL.





So basically, code like


<?php setlocale(LC_ALL, 'Czech_Czech Republic.65001'); // 65001 is UTF-8 codepage ?>


does not work on Windows at all.





(written in time of PHP 5.2.4)

de ronino at kde (reverse it) 25-Jun-2008 02:43


I experienced the behavior stated in the above Warning box: Running PHP5 on a multithreaded Apache made the current locale change sometimes all of a sudden within a script, so strftime() output wasn't in the required format.



I recompiled Apache with the prefork MPM and now it works like a charm. Took me a long time to find out the reason as I overlooked the warning box searching for either a bug report or a programming error of mine...

jonas at jonashaag dot de 27-May-2008 12:11


On Ubuntu, you have to take p.e. "de_DE.utf8", all available languages you can get with:

    locale -a

bryn AT lunarvis DOT com 21-Jan-2008 05:04


Posting this in the hope it might be useful to others, as I could find very little info anywhere. If you want to use a Welsh locale and have the suitable language support installed, you pass 'cym' (abbreviated form of Cymraeg) to setlocale:



<?php

setlocale(LC_TIME, 'cym');

$welsh= gmstrftime("%A, %B %Y - %H:%M",time());

echo $welsh;

?>



The above certainly applies to Windows systems, but should also apply to Unix if the required support is installed.



Cheers,



Bryn.

ostapk 27-Dec-2007 02:39


There is a new PECL extension under development called intl (it will be available in PHP5.3). Meanwhile all who rely on the setlocale() and friends should be aware about the limitations of them as covered in this post on the onPHP5.com blog: http://www.onphp5.com/article/22

Periklis 13-Sep-2007 02:33


In *some* Windows systems, setting LC_TIME only will not work, you must either set LC_ALL or both LC_CTYPE and LC_TIME. BUT if you have already set LC_TIME using setlocale earlier in the script, dates will not be affected! For example:

<?php

setlocale(LC_TIME, 'greek');

setlocale(LC_CTYPE, 'greek');

?>

will not work, while 

<?php

setlocale(LC_CTYPE, 'greek');

setlocale(LC_TIME, 'greek');

?>

will do the job.

mvanbaak 09-May-2007 05:03


To complement Sven K's tip about debian:



You can also install the package locales-all

That one holds all the locales there are in compiled form.

szepeshazi at gmail dot com 18-Feb-2007 07:11


For those of you who are unfortunate enough (like me) to work in Windows environment, and try to set the locale to a language _and_ to UTF-8 charset, and were unable to do it, here is a workaround.



For example to output the date in hungarian with UTF-8 charset, this will work:



    $dateString = "%B %d., %A";

    setlocale(LC_ALL,'hungarian');

    $res=strftime($dateString);

    echo(iconv('ISO-8859-1', 'UTF-8', $res));



If anybody knows how to set the locale on Windows to the equivalent of "hu_HU.UTF-8" on unix, please do tell me.

lifeless 20-Nov-2006 09:40


if your server is an ubuntu (debian like)

you need to install the locales you want (default is english and your language) go to aptitude and install -language-pack-*-base it will resolve dependencies and will try to install a suggested package, remove it if you don't care and proceed.

Sven K 07-Jun-2006 03:08


If your system doesn't show any installed locales by "locale -a", try installing them by "dpkg-reconfigure locales" (on debian).

08-Mar-2006 12:17


The example from bruno dot cenou at revues dot org below shows the possibility, but I want to spell it out: you can add charset info to setlocale.



Example:



Into my utf-8-encoded page I want to insert the name of the current month, which happens to be March, in German "M?rz" - with umlaut. If you use



   setlocale(LC_TIME, 'de_DE');

   echo strftime("%B");



this will return "M&auml;rz", but that html-entity will look like this on a utf-8 page: "M?rz". Not what I want.



But if you use



   setlocale(LC_TIME, 'de_DE.UTF8');  // note the charset info !

   echo strftime("%B");



this returns "M√§rz", which, on utf-8, looks like it should: "M?rz".

Debian users: Addition to Gabor Deri's note: if setlocale doesn't work in your locale and you're on Debian, and Gabor Deri's note doesn't work, you have to install the locales package.



As root, type: "apt-get install locales" and it will be installed.

In most Unix/Linux system, you could use:



locale -a



This will list all available locales on the server.

When i tried to get the current locale (e.g. after i set the lang to german with setlocale(LC_ALL, 'de_DE'); ), the following did not work on my suse linux 9.0-box:

$currentLocale = setlocale(LC_ALL, NULL);

This code did a reset to the server-setting.



$currentLocale = setlocale(LC_ALL, 0); works perfectly for me, but the manual says NULL and 0 are equal in this case, but NULL seems to act like "".

!!WARNING!!



The "locale" always depend on the server configuration.



i.e.:

When trying to use "pt_BR" on some servers you will ALWAYS get false. Even with other languages.



The locale string need to be supported by the server. Sometimes there are diferents charsets for a language, like "pt_BR.utf-8" and "pt_BR.iso-8859-1", but there is no support for a _standard_ "pt_BR".



This problem occours in Windows platform too. Here you need to call "portuguese" or "spanish" or "german" or...



Maybe the only way to try to get success calling the function setlocale() is:

setlocale(LC_ALL, "pt_BR", "pt_BR.iso-8859-1", "pt_BR.utf-8", "portuguese", ...);



But NEVER trust on that when making functions like date conversions or number formating. The best way to make sure you are doing the right thing, is using the default "en_US" or "en_UK", by not calling the setlocale() function. Or, make sure that your server support the lang you want to use, with some tests.



Remember that: Using the default locale setings is the best way to "talk" with other applications, like dbs or rpc servers, too.

On Novell Netware, the language codes require hyphens, not underscores, and using anything other than LC_ALL doesn't work directly.



So... (from their support list)....



You have to set TIME, NUMERIC etc. info in two steps as given below rather than one. This is due to the limitation of setlocale function of LibC.

<?php

   setlocale(LC_ALL, 'es-ES');

   $loc = setlocale(LC_TIME, NULL);

   echo strftime("%A %e %B %Y", mktime(0, 0, 0, 12, 22, 1978));

  // jeuves 22 diciembre 1978

?>

This should work.



or of course, reset LC_ALL...

<?php

setlocale(LC_ALL, 'es-ES');

echo strftime("%A %e %B %Y", mktime(0, 0, 0, 12, 22, 1978));

setlocale(LC_ALL, '');

// jeuves 22 diciembre 1978

?>

Be carefull - setting a locale which uses commas instead of dots in numbers may cause a mysql db not to understand the query:


<?php


setlocale(LC_ALL,"pl");


$price = 1234 / 100; // now the price looks like 12,34


$query = mysql_query("SELECT Id FROM table WHERE price='".$price."'");


?>


Even if there is a price 12.34 - nothing will be found

be careful with the LC_ALL setting, as it may introduce some unwanted conversions. For example, I used 



setlocale (LC_ALL, "Dutch");



to get my weekdays in dutch on the page. From that moment on (as I found out many hours later) my floating point values from MYSQL where interpreted as integers because the Dutch locale wants a comma (,) instead of a point (.) before the decimals. I tried printf, number_format, floatval.... all to no avail. 1.50 was always printed as 1.00 :(



When I set my locale to :



 setlocale (LC_TIME, "Dutch");



my weekdays are good now and my floating point values too. 



I hope I can save some people the trouble of figuring this out by themselves.

Under FreeBSD, locale definitions are stored in the /usr/share/locale/ directory. Danish time formats and weekdays, for instance, are stored in /usr/share/locale/da_DK.ISO_8859-1/LC_TIME.

On windows:


Control Panel->International Settings


You can set your locale and customize it


And locale-related PHP functions work perfectly

Morgan Christiansson <mog at linux dot nu> 29-Mar-2000 12:56


check /usr/share/locale/ if you want more info about the locale available with your *NIX box





there is also a file called /usr/share/locale/locale.alias with a list of aliases


such as swedish for sv_SE





so on all boxes i have accounts on (rh 6.0 and slack 3.4) you can just use setlocale("LC_ALL","swedish"); or other prefered language in plain english.





However, the weekdays were in all lowercase :(





Note: export LC_ALL=swedish made a lot of programs swedish for me, it's also possible to make them russian or japanese :)
