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.

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.

| 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.

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'";
?>
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().
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.
