chunk_split

Description

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 every chunklen (defaults to 76) chars the string end (defaults to "\r\n"). It returns the new string leaving the original string untouched.

Example 1. Chunk_split() example # format $data using RFC 2045 semantics $new_string = chunk_split (base64_encode($data));

This function is significantly faster than ereg_replace().
