chunk_split

Split a string into smaller chunks (PHP 3>= 3.0.6, PHP 4 )
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 910. chunk_split() example

<?php
// format $data using RFC 2045 semantics
$new_string = chunk_split(base64_encode($data));
?>
