Description:
------------
function wordwrap:

----
Example 1:
$text = "The quick brown fox jumped over the lazy dog.";
$newtext = wordwrap( $text, 20 );
echo "$newtext\n";

Example 1 output:
The quick brown fox
jumped over the
lazy dog.

This is rather misleading to new users, they seem to be expecting their output to be shown with carriage returns in html (since php defaults with text/html mime-type.) Perhaps using a <pre> tag around output:

echo "<pre>$newtext</pre>"

Or using the break parameter in the function:

$newtext = wordwrap( $text, 20, '<br>');

This applies to both example 1 and 2.

Thanks.
