Example
<pre>
<?php
require_once 'function.str_chop.php';
$longtext = "this is some really long text with long words that should be chopped";
$longlink = "http://thisisareally.longlink/with/lots/of/stupid/paths/";
// Chop at default length
echo str_chop($longtext);
echo "\n";
// Chop in the middle
echo str_chop($longtext, 60, true);
echo "\n";
// Chop a link
echo str_chop($longlink, 40, true);
echo "\n";
// Chop a link whirlpool style
echo "<a href=\"$longlink\">" . str_chop($longlink, 40, true) . '</a>';
?>
</pre>
