获取数字格式信息

说明

返回包含本地化数字和货币格式信息的关联数组。

返回值

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

Thep_sign_posn,andn_sign_posncontain 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 toCHAR_MAX, no further grouping is done. If an array element is equal to 0, the previous element should be used.

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])...
