array str_split ( string string [, int split_length] )
Converts a string to an array. 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.
