chunk_split -- Split a string into smaller chunks
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.
     
| Example 1. chunk_split() example | 
<?php// format $data using RFC 2045 semantics
 $new_string = chunk_split(base64_encode($data));
 ?>
