问题
I'm running PHP
on windows vista
. So, I'm trying to get to know how locale functions work. I started with
setlocale(LC_ALL, $locale)
and localeconv()
At first it worked with CLDR locale IDs(I think.., Just started learning PHP locales) like "en_US", "en_UK", etc, resulting as demonstrated in the PHP documentation examples. But now setlocale()
and localeconv()
only works with $locale
values like "English_United Kingdom.1252"
and "English_United States.1252"
which I believe is windows based locale IDs.
So when I do:
var_dump(setlocale(LC_ALL, "en_US"));
var_dump(localeconv());
I get these results:
boolean false
array (size=18)
'decimal_point' => string '.' (length=1)
'thousands_sep' => string '' (length=0)
'int_curr_symbol' => string '' (length=0)
'currency_symbol' => string '' (length=0)
'mon_decimal_point' => string '' (length=0)
'mon_thousands_sep' => string '' (length=0)
'positive_sign' => string '' (length=0)
'negative_sign' => string '' (length=0)
'int_frac_digits' => int 127
'frac_digits' => int 127
'p_cs_precedes' => int 127
'p_sep_by_space' => int 127
'n_cs_precedes' => int 127
'n_sep_by_space' => int 127
'p_sign_posn' => int 127
'n_sign_posn' => int 127
'grouping' =>
array (size=0)
empty
'mon_grouping' =>
array (size=0)
empty
How do I make my scripts respond to CLDR locale IDs?
回答1:
setlocale() returns false in your case. Manual:
Returns the new current locale, or FALSE if the locale functionality is not implemented on your platform
Try to use one of: "usa", "america", "united states", "united-states", or "us"

回答2:
The setlocale
, localeconv
, and related functions do not work with Unicode CLDR locale identifiers or data. Instead, they vary per operating system, with POSIX locale identifiers and data on *nix systems and Microsoft locale strings and data on Windows.
# works only on Linux after running `locale-gen de_DE.UTF-8`
# but Windows requires an entirely different locale identifier
setlocale(LC_ALL, 'de_DE.UTF-8');
$locale = localeconv();
echo number_format(
1234.5,
1, # fraction digits
$locale['decimal_point'],
$locale['thousands_sep']
); # '1.234,5'
If you’d actually like to use Unicode CLDR locale identifiers and data for a unified experience regardless of your operating system, use the International extension instead. It’s available with PHP 5.3 and is a wrapper around the ICU (International Components for Unicode) library, which provides standardized CLDR locale data.
$fmt = new NumberFormatter('de-DE', NumberFormatter::DECIMAL); # or 'de_DE'
echo $fmt->format(1234.5); # '1.234,5'
