localeconv — Get numeric formatting information

说明

array localeconv ( void )

Returns an associative array containing localized numeric and monetary formatting information.

返回值

localeconv() returns data based upon the current locale as set by setlocale(). The associative array that is returned contains the following fields:

Array element	Description
decimal_point	Decimal point character
thousands_sep	Thousands separator
grouping	Array containing numeric groupings
int_curr_symbol	International currency symbol (i.e. USD)
currency_symbol	Local currency symbol (i.e. $)
mon_decimal_point	Monetary decimal point character
mon_thousands_sep	Monetary thousands separator
mon_grouping	Array containing monetary groupings
positive_sign	Sign for positive values
negative_sign	Sign for negative values
int_frac_digits	International fractional digits
frac_digits	Local fractional digits
p_cs_precedes	`TRUE` if currency_symbol precedes a positive value, `FALSE` if it succeeds one
p_sep_by_space	`TRUE` if a space separates currency_symbol from a positive value, `FALSE` otherwise
n_cs_precedes	`TRUE` if currency_symbol precedes a negative value, `FALSE` if it succeeds one
n_sep_by_space	`TRUE` if a space separates currency_symbol from a negative value, `FALSE` otherwise
p_sign_posn	0 - Parentheses surround the quantity and currency_symbol 1 - The sign string precedes the quantity and currency_symbol 2 - The sign string succeeds the quantity and currency_symbol 3 - The sign string immediately precedes the currency_symbol 4 - The sign string immediately succeeds the currency_symbol
n_sign_posn	0 - Parentheses surround the quantity and currency_symbol 1 - The sign string precedes the quantity and currency_symbol 2 - The sign string succeeds the quantity and currency_symbol 3 - The sign string immediately precedes the currency_symbol 4 - The sign string immediately succeeds the currency_symbol

The p_sign_posn, and n_sign_posn contain a string of formatting options. Each number representing one of the above listed conditions.

The grouping fields contain arrays that define the way numbers should be grouped. For example, the monetary grouping field for the nl_NL locale (in UTF-8 mode with the euro sign), would contain a 2 item array with the values 3 and 3. The higher the index in the array, the farther left the grouping is. If an array element is equal to CHAR_MAX, no further grouping is done. If an array element is equal to 0, the previous element should be used.

范例

Example #1 localeconv() example


<?php
if (false !== setlocale(LC_ALL, 'nl_NL.UTF-8@euro')) {
    $locale_info = localeconv();
    print_r($locale_info);
}
?>

以上例程会输出：

Array
(
    [decimal_point] => .
    [thousands_sep] =>
    [int_curr_symbol] => EUR
    [currency_symbol] => €
    [mon_decimal_point] => ,
    [mon_thousands_sep] =>
    [positive_sign] =>
    [negative_sign] => -
    [int_frac_digits] => 2
    [frac_digits] => 2
    [p_cs_precedes] => 1
    [p_sep_by_space] => 1
    [n_cs_precedes] => 1
    [n_sep_by_space] => 1
    [p_sign_posn] => 1
    [n_sign_posn] => 2
    [grouping] => Array
        (
        )

    [mon_grouping] => Array
        (
            [0] => 3
            [1] => 3
        )

)

The C99 standard modified slightly the definition of the international currency symbol, which is now 4 characters long instead of 3 in previous definitions. The fourth character will most often be an ASCII space, but its effective value is the locale-specific spacing character used for numeric grouping (i.e. the one refered by [sep_by_space] and [grouping])...
