chunk_split
Description
string 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.
See also str_split(), explode(), split(), wordwrap() and RFC 2045.
