/**
* Sorts an array with maintaining index association, elements will be arranged from the lowest to the highest.
* @param array $array The input array.
* @param int $sort_flag (optional) Shows how elements of the array to be compared.
* @param string $language (optional) The language in which comparison is to be made. If language is omitted, interface language is assumed then.
* @param string $encoding (optional) The used internally by this function character encoding. If it is omitted, the platform character set will be used by default.
* @return bool Returns TRUE on success, FALSE on error.
* Note: $sort_flag may have the following values:
* SORT_REGULAR - internal PHP-rules for comparison will be applied, without preliminary changing types;
* SORT_NUMERIC - items will be compared as numbers;
* SORT_STRING - items will be compared as strings. If intl extension is enabled, then comparison will be language-sensitive using internally a created ICU locale;
* SORT_LOCALE_STRING - items will be compared as strings depending on the current POSIX locale. If intl extension is enabled, then comparison will be language-sensitive using internally a created ICU locale.
* This function is aimed at replacing the function asort() for sorting human-language strings.
