chunk_split -- Split a string into smaller chunksDescriptionstring chunk_split ( string body [, int chunklen [, string end]] )

Can be used to split a string into smaller chunks which is useful for
e.g. converting base64_encode() output to match RFC
2045 semantics. It inserts end (defaults to
"\r\n") every chunklen characters (defaults to
76). It returns the new string leaving the original string untouched.
