setlocale (PHP 3, PHP 4 , PHP 5) setlocale -- Set locale information Descriptionstring setlocale ( mixed category, string locale [, string ...]) string setlocale ( mixed category, array locale)
category is a named constant (or string)
specifying the category of the functions affected by the locale
setting:
LC_ALL for all of the below
LC_COLLATE for string comparison, see
strcoll()
LC_CTYPE for character classification and conversion, for
example strtoupper()
LC_MONETARY for localeconv()
LC_NUMERIC for decimal separator (See also
localeconv())
LC_TIME for date and time formatting with
strftime()
注:
As of PHP 4.2.0, passing category as a string is
deprecated, use the above constants instead. Passing them as a string
(within quotes) will result in a warning message.
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.
注:
Passing multiple locales is not available before PHP 4.3.0
Setlocale 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.
注:
The return value of setlocale() depends
on the system that PHP is running. It returns exactly
what the system setlocale function returns.

It is written nowhere, that setlocale() can be used for simple mathematical
operations like adding, substracting, dividing or multiplying. The code
below gives correct results:
setlocale(LC_ALL,
"pl");
$net = "1234,56";
$gross =
"1,22" * $net;
printf("gross: %s, net: %s", $gross,
$net");
/* Polish VAT tax is 22% */
Result of this code
is:
gross: 1234,56, net: 1506,1632
So, every one can use his own
decimal point for mathematical operations without any error or warning
(PHP3.0.3).
