 * Converts a string to an array.

 * @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 array						The result array of chunks with the spcified length.
 * Notes:
 * If the optional split_length parameter is specified, the returned array will be broken down into chunks
 * with each being split_length in length, otherwise each chunk will be one character in length.
 * FALSE is returned if split_length is less than 1.
 * If the split_length length exceeds the length of string, the entire string is returned as the first (and only) array element.
 * This function is aimed at replacing the function str_split() for human-language strings.
