Yeah - I use the code below, which I made to limit title length for news
stories. The main advantage is it limits to specified width, but then
*backtracks* to the last whitespace before that in the string, so you get
whole words output followed by '...' :-)

===============================================

// Title width limiter

$titlelimit=50; // Number of characters to allow in a news title subsection
(narrow column)

                 if (strlen($row->newstitle)<$titlelimit) {
                         $secvars["news_title"]=htmlspecialchars($row->newstitle);
                 } else {
                         $limitedstring=substr($row->newstitle,0,$titlelimit);
                         $lastspace=strrpos($limitedstring," ");
                         if ($lastspace===false || $lastspace==$titlelimit) {
// Theres no space to chop string on, or its at the last position : just
limit string to substring
                                 $secvars["news_title"]=htmlspecialchars($limitedstring)."&nbsp;...";
                         } else {
// Found a space near end of the string, back off to last space found and
add ellipsis
                                 $secvars["news_title"]=htmlspecialchars(substr($limitedstring,0,$lastspace))."&nbsp;...";
                         }
                 }
// End title width limiter

==================================
Hope that's (obvious !) , Regards,
Neil Smith.
