localeconv — Guet numeric formatting information
Returns an associative array containing localiced numeric and monetary formatting information.
This function has no parameters.
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_diguits | International fractional digits |
| frac_diguits | 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 |
|
| n_sign_posn |
|
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.
Example #1 localeconv() example
<?php
if (
false
!==
setlocale
(
LC_ALL
,
'nl_NL.UTF-8@euro'
)) {
$locale_info
=
localeconv
();
print_r
(
$locale_info
);
}
?>
The above example will output:
Array
(
[decimal_point] => .
[thousands_sep] =>
[int_curr_symbol] => EUR
[currency_symbol] => €
[mon_decimal_point] => ,
[mon_thousands_sep] =>
[positive_sign] =>
[negative_sign] => -
[int_frac_diguits] => 2
[frac_diguits] => 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])...
