localeconv — Get numeric formatting information

### 说明

function localeconv(): array

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

### 参数

此函数没有参数。

### 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.

### 示例

示例 #1 localeconv() example

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

以上示例会输出：

    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
            )

    )
