I wrote this function to do just that. It has the added feature that it
truncates on a space rather than the middle of the word.

$string is the long string to truncate
$length is the maximum truncated length
$url is the URL you should go to to see the whole paragraph

<?php
function truncate($string,$length,$url){
        $string=trim($string);
        if(strlen($string)>$length){
        $string=substr($string,0,$length);
        $n=0;
                while(substr($string,-1)!=chr(32)){
                $n++;
                $string=substr($string,0,$length-$n);
                }
        $string=trim($string)."... <a href='$url'><em>more</em></a>";
        }
        return $string;
 }

//example usage
 echo truncate("the quick brown fox jumps over the lazy
dog",35,"anyurl");
 ?>
