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.

Hi,

I have done a similar thing that worked reasonably well in Visual Basic 
(however, included is a PHP snippet which might do the trick - I am not a 
PHP pro).

write a small PHP function to select only a part of the string, say the 
first 15 characters, and append "..." to the string, for example,

     thisisoneveryveryveryveryverylongword!!!!

will become:

     thisisoneveryver...

This is standard PHP string manipulation, which might look something like 
this:

    function myTruncate ($verylongstring, $length) {
        if (strlen($verylongstring) > $length) {
            $shorterstring = substr($verylongstring,0,$length-1) . "...";
        }
        else
            $shorterstring = $verylongstring;
        }
        return $shorterstring;
    }
