[RESOLVED] Splitting up text into chunks (no split words)

[hadoob024]

I'm trying to figure out the best way to split up a body of text (say maybe 400-500 characters long) into 130 character-sized chunks with no words being split. I figured how to do this for the first chunk, but am having problems figuring out how to keep repeating it. Been playing around with this for a while, and came up with the following, but can't seem to figure out why it's not working. Any thoughts?

$inc = -1;
$body_length = 0;
$tmp_chunk = 1;
$tmp_body = '';
$body = '';
$tmp_start = 1;
$final_chunk = 0;

$body = 'On the Insert tab, the galleries include items that are designed to coordinate with the overall look of your document. You can use these galleries to insert tables, headers, footers, lists, cover pages, and other document building blocks. When you create pictures, charts, or diagrams, they also coordinate with your current document look.';

$body_length = length($body);

do
  if (($tmp_start + 130) > $body_length) {
    $tmp_body = substr($body, $tmp_start, $body_length - $tmp_start);
    $final_chunk = 1;}
  else {
    $tmp_body = substr($body, $tmp_start, 130);}


  while (substr(tmp_body, inc, 1) != ' ')
      $inc = $inc - 1;
  endwhile;

  $tmp_body = substr($tmp_body, $tmp_start, 130 + $inc);
  $tmp_start = $tmp_start + 130 + $inc;

  echo $tmp_body;

  $tmp_chunk = $tmp_chunk + 1;
  $inc = -1;
  $tmp_body = NULL;


while ($final_chunk = 0);

Have you looked at the [man]wordwrap/man function yet?

Cool. Thanks. Yeah, I just looked at it. Quick follow-up though. Instead of just echo-ing out each chunk, I need to store each chunk into a variable. Wordwrap() doesn't seem to allow this, does it?

[hadoob024]

Just figured it out. The following line:

$tmp_body = substr($tmp_body, $tmp_start, 130 + $inc);

needed to be this instead:

$tmp_body = substr($tmp_body, 1, 130 + $inc);

What you can do with wordwrap() is specify the optional separator parameter, then explode() the result on that separator, e.g.:

<?php
$text = 'abc defgh, ijkl mnop q rstuv wx yz.';
define('SEP', '<{[SEP]}>');
$parts = explode(SEP, wordwrap($text, 10, SEP));

// show reults:
echo "<pre>".print_r($parts,1)."</pre>";
// ouputs:
/*
Array
(
    [0] => abc defgh,
    [1] => ijkl mnop
    [2] => q rstuv wx
    [3] => yz.
)
*/
?>

Sweet! That worked too. Thanks!
