different names on different systems or for providing a fallback

Returns the new current locale, or &false; if the locale functionality is

An invalid category name also causes a warning message. Category/locale

Different systems have different naming schemes for locales.

The return value of <function>setlocale</function> depends

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
|
|
<function>setlocale</function>. This happens due to other scripts
|
|
running in different threads of the same process at the same time,
|
|
changing the process-wide locale using <function>setlocale</function>.
|
|
</para>
|
|

<para>
|
|
Windows users will find useful information about
|
|
<parameter>locale</parameter> strings at Microsoft's
|
|
<acronym>MSDN</acronym> website. Supported language strings can be found
|
|
in the
|
|
<link xlink:href="&url.setlocale.lang.win32;">language strings documentation</link>
|
|
and supported country/region strings in the
