setlocale

(PHP 4, PHP 5)

setlocale — Set locale information

Popis

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

category je řetězec určující kategorii funkcí ovlivněných nastavením locale:

LC_ALL pro všechny níže uvedené kategorie
LC_COLLATE pro porovnávání řetězců - v PHP v současnosti neimplementováno
LC_CTYPE pro klasifikaci a konverzi znaků, např. strtoupper()
LC_MONETARY pro localeconv() - v PHP v současnosti neimplementováno
LC_NUMERIC pro oddělovač desetinných míst
LC_TIME pro formátování data a času pomocí strftime()

Pokud je locale prázný řetězec (""), názvy locale se nastaví na hodnoty systémových proměnných se stejnými jmény jako mají výše uvedené kategorie, nebo z "LANG".

Pokud je locale nula nebo "0", locale se nezmění, pouze se vrátí současná hodnota.

setlocale() vrací nové aktuální locale nebo FALSE, pokud na dotyčné platformě není funkcionalita locale implementována, zadané locale neexistuje, nebo je název kategorie neplatný. Neplatný název kategorie také vyvolá varování.

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.

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.

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.

If you already have all the locales installed and "locale -a" is only showing a few languages, then edit /etc/locale.gen and add a line, e.g., es_MX ISO-8859-1.  After you add the line, run the command locale-gen for it to generate the locales based on those settings.

Just in case you freshly installed some new locales and they doesn't seem to work with setlocale(), don't forget to restart your webserver. It may save you some time browsing your code trying to fix it there :)

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

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 "März" - 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: "März".

A little function to test available locales on a sytem :



<?php

function list_system_locales(){

    ob_start();

    system('locale -a'); 

    $str = ob_get_contents();

    ob_end_clean();

    return split("\\n", trim($str));

}



$locale = "fr_FR.UTF8";

$locales = list_system_locales();



if(in_array($locale, $locales)){

        echo "yes yes yes....";

}else{

        echo "no no no.......";

}



?>

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 "".

When you use Smarty's html_select_date,

you can use setlocale(LC_TIME, string local) in your script before display the template file

then get the local month name,

also, you can copy the "plugins/function.html_select_date.php" to "plugins/function.html_select_date_local.php",

and modify the function name to smarty_function_html_select_date_local(former is smarty_function_html_select_date)



for more examples about this function, you can visit my php blog( http://php.clickz.cn/ ) to find more.



this resource's link is http://php.clickz.cn/articles/date/setlocale.html



example test:

<?php

setlocale(LC_TIME,"chs");



$smarty->display("setlocale.tpl");



?>



the setlocale.tpl's content

-------------------------

<html>

<head>My PHP Blog</head>

<body>

{ html_select_date_local prefix="" time=$smarty.get.date month_format="%B" all_extra="onChange='theFormSubmit();'" end_year=+1 }

</body>

</html>

!!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

?>

On some systems (at least FreeBSD 4.x) the format for a `locale' is, for example, ro_RO.ISO8859-2. If you use ro_RO instead setlocale will return FALSE. Just browse in /usr/share/locale and see what is the name of the directory holding your `locale' and use that name in your scripts:



<?php

  clearstatcache();

  $pos = strrpos ($_SERVER["PHP_SELF"], "/");

  $fisier = substr ($_SERVER["PHP_SELF"], $pos + 1);

  $result = filemtime ($fisier);

  $local = setlocale (LC_TIME, 'ro_RO.ISO8859-2');

  if ($local == "ro_RO.ISO8859-2") {

    $modtime = strftime '%e&nbsp;%B&nbsp;%Y&nbsp;%H:%M', $result);

  } else {

    $modtime = strftime ('%d.%m.%Y&nbsp;%H:%M', $result);

  }

  printf ("Ultima&nbsp;actualizare: %s\\n", $modtime);

?>

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.

IMPORTANT notice for DEBIAN linux users:



after the upgrade to the new stable (woody), you may have encountered that setlocale is not working at all, even though you have the files in the /usr/share/locale directory and everything was fine before the upgrade. in this case look at the /etc/locale.gen file, which contains the generated locales. if it is empty, you do not have any useful locales. to generate the needed locales run 'dpkg-reconfigure locales' as root and select the locales you need.

I needed to compile and install some extra locales to get this to work on RH7.3. Probably just me not doing a proper installation, but this is what it took to fix it:



localedef -ci no_NO -f ISO_8859-1 no_NO

In FreeBSD I had to use no_NO.ISO8859-1 instead of just no_NO..



<?PHP

    setlocale (LC_ALL, 'no_NO.ISO8859-1');

    echo strftime ("%A %e %B %Y", time());

?>

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>

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 :)

The Open Group has an excellent document available on the setlocale() library function, most of which applies to the PHP function of the same name.





http://www.opengroup.org/onlinepubs/7908799/xbd/locale.html





WARNING: This document might be a little too complex for people who came from HTML to PHP.





If you migrated from the world of C programming you'll be a locale master after reading this document.
