<parameter>Category</parameter> is a named constant (or string)

If <parameter>locale</parameter> is the empty string
|
|
<literal>""</literal>, the locale names will be set from the
|
|
values of environment variables with the same names as the above
|
|
categories, or from "LANG".
|
|
</para>
|
|
<para>
|
|
If <parameter>locale</parameter> is zero or <literal>"0"</literal>, the locale setting
|
|
is not affected, only the current setting is returned.
|
|
</para>
|
|
<para>
|
|
If <parameter>locale</parameter> 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 usefull if a locale is known under
|
|
different names on different systems or for providing a fallback
|
|
for a possibly not available locale.
|
|
</para>
|
|
<note>
|
|
<simpara>
|
|
Passing multiple locales is not available before PHP 4.3.0

</simpara>
|
|
</note>
|
|
<para>
|
|
Setlocale returns the new current locale, or &false; if the locale
|
|
functionality is not implemented in the 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 <ulink url="&url.rfc;1766">RFC 1766</ulink>
|
|
and <ulink url="&url.iso-639;">ISO 639</ulink>.

</para>

<para>
|
|
The return value of <function>setlocale</function> depends
|
|
on the system that PHP is running. It returns exactly
|
|
what the system setlocale function returns.
