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));
?>
