PHP: chunk_split

chunk_split

(PHP 3 >= 3.0.6, PHP 4, PHP 5)

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)); ?>

the best way to solve the problem with the last string added by chunk_split() is:





<?php


$string = '1234';


substr(chunk_split($string, 2, ':'), 0, -1);


// will return 12:34


?>

>> chunk_split will also add the break _after_ the last occurence.



this should be not the problem 



substr(chunk_split('FF99FF', 2, ':'),0,8);

will return FF:99:FF

[Editor's note: You can always use wordwrap('FF99FF', 2, ':', 2); to avoid this]





chunk_split will also add the break _after_ the last occurence.  So, attempting to split a color into base components,


chunk_split('FF99FF', 2, ':');


will return FF:99:FF:
